neatly, that took fairly a very long time. After what appears like eons of nudging and cajoling and pushing, IBM is making the IBM i operating system and its integrated database management device, as neatly because the application development tools and other systems utility, accessible on its self-branded IBM Cloud public cloud.
large Blue previewed its plans to deliver each IBM i and AIX to the IBM Cloud at its annual feel conference in Las Vegas, on scale out machines aimed toward small and medium organizations in addition to to customers who are looking to run clusters of machines, and on scale up techniques which have NUMA electronics that greater tightly cluster them into shared memory programs.
There are lots of questions about how this could be all be packaged up and bought below the unwieldy name of the IBM vigour techniques digital Server on IBM Cloud. however we will inform you all that we know and fill you in as we gain knowledge of extra.
The power systems slices served up on the IBM Cloud running IBM i and AIX have been first rolled out for early entry to chosen consumers to look at various the APIs for the manage plane, which we presume is in accordance with the PowerVC implementation of OpenStack. The initial valued clientele who're kicking the tires have been alleged to only install development and look at various environments or protype code, by no means the rest running in construction. This changed into totally meant to be a proof of thought setup at this element, as which you can see from the rollout roadmap:
The alpha and beta checking out for the vigour techniques slices on the IBM Cloud is on an exquisite quickly song, running from February into March, as that you could see, and widespread availability is slated for a while in March. probably someplace in opposition t the end, we would wager. IBM is at the beginning making the vigor puffs – what else are you able to name them as shorthand? – accessible within the early access exams in its US East datacenter within the Washington DC metro area; it isn't clear what iron turned into used. The alpha and beta checking out is being finished on a collection of energy S922 scale out machines, which might be in keeping with a pair of Power9 processors and which frankly is a large box for many IBM i shops all through itself, as well as on vigour E880 scale up systems, which might be being scaled up to sixteen sockets and which use the older Power8 processors. all the machines use ten-core processors, which can be the candy spot between performance, chip yield, and price within the vigor programs line. The Power9 chips within the vigour S922 servers run at 2.eight GHz and can turbo up to three.9 GHz if there is satisfactory thermal headroom; these chips seem like they may have 4 threads per core (also called SMT4), which isn't as a whole lot threading as the usual Power8 chip offers in scale out machines with SMT8 threading (eight threads per core) and twice as many cores per die (24 cores versus 12 cores). Anyway, it feels like the vigor S922 is being outfitted with the heavy cores, now not the easy ones. The Power8 chips within the vigour E880 are working at four.19 GHz and additionally assist SMT8 threading (there turned into only a heavy core here); all sixteen cores are populated with ten-core Power8 chips, with a maximum scalability of one hundred sixty cores in a single logical partition on the IBM Cloud.
both of the machines are being configured with 32 GB reminiscence sticks, that are again on the candy spot between ability, bandwidth, and cost per bit, and IBM is enabling customers to configure the machines with any place from 8 GB to sixty four GB of leading reminiscence per core. in case you desire denser reminiscence to bolster the potential, you can double it up using sixty four GB reminiscence sticks, after which double it up once more to 128 GB sticks, however this may be a custom order and it will can charge significantly extra, we think. IBM is offering disk and flash storage as much as 2 TB for local storage on the situations and starting to be at 10 GB increments. exterior storage for applications and databases is on Storwize V7000 disk arrays in the racks close this vigor iron, and are linked to the servers by Fibre Channel switches. valued clientele can share machines or appoint dedicated iron, depending on their proclivities for absolute protection and coping with noisy neighbors on the digital infrastructure.
Steve Sibley vice chairman and offering manager for the Cognitive methods division at IBM, gave me a sneak peek on the future vigour cloud slices on a seek advice from to the Austin, Texas labs final week, ahead of the believe convention. right here is how the points and capabilities of the logical partitions on the IBM Cloud are shaping up:
Sibley instructed us that the pricing changed into no longer yet set in stone for the virtual vigour skill on the IBM Cloud, however when pressed about comparing the can charge between buying gear and renting it on the cloud, Sibley estimated that for a given IBM i or AIX workload working on in a similar way configured hardware and logical partitions, operating the cloud illustration would cost about 30 percent to 40 p.c greater on the example running full out over three years in comparison to purchasing the iron and the usage of it for 3 years. The change, of direction, is that IBM is managing the power programs and paying for the datacenter, the electrical energy, the cooling, the safety, patch updates on firmware, the installation of the PowerVM hypervisor and its update, and the installing of the IBM i or AIX operating equipment. When corporations buy their own vigor techniques machines, except they get augmented features from IBM or a business accomplice, it’s all on them. Pricing for the virtual machines, the memory, the storage, and the operating system and databases are all set per hour.
by the way, it is not clear what IBM i and AIX releases are supported on the machines, however most likely the current IBM i 7.2 and IBM i 7.3 releases are supported on the IBM Cloud as well as AIX 7.1 and AIX 7.2, which might be additionally present. Linux isn't mentioned as a supported platform, but SAP HANA workloads are and that suggests that there is a Linux – and principally red Hat enterprise Linux – beneath it due to the fact that HANA in-reminiscence databases aren't supported on any Unix variant, or IBM i for that rely.
by using March, IBM plans to have the IBM i and AIX instances attainable in construction in its US East (Washington DC) and US South (Dallas) areas, and within the second quarter IBM plans to roll it in its European datacenter in its european principal (Frankfurt) location, with different datacenters popping out as demand pulls and IBM pushes.
we can take a look at the pricing as soon because it turns into accessible and see how it all stacks up, and get the ideas of different IBM i cloud gamers about what large Blue is doing.

IBM tweaked its enterprise storage techniques these days, adding skinny provisioning to its device Storage DS8000, and asynchronous mirroring and twin processors to its XIV Storage device. In each situations, the facets are already included in opponents' systems and fill gaps in IBM's platforms.
IBM left out thin provisioning when it upgraded the DS8000 remaining February with full disk encryption and strong-state force (SSD) help. First made popular by 3PAR Inc., skinny provisioning is fitting a standard function on commercial enterprise methods now that Hitachi statistics techniques (HDS) and EMC Corp. offer it. IBM already helps thin provisioning for its SAN quantity Controller (SVC) storage virtualization container, and on the XIV Storage device.along with skinny provisioning, IBM is making utility improvements for the DS8000 that are supposed to enhance the speed of quantity initiation and supply more advantageous throughput for methods the usage of FICON on IBM mainframes.
XIV remains a work in progress
IBM acquired XIV methods in January 2008, and launched its first IBM-branded XIV system remaining September. Critics claimed the XIV lacked enterprise features equivalent to asynchronous mirroring for distance replication, scalability beyond one hundred eighty TB uncooked, guide for IBM gadget z mainframes and concurrent code load for non-disruptive utility setting up.
state-of-the-art upgrade offers the XIV Storage gadget asynchronous mirroring and concurrent code load, however the other obstacles remain.
"we've been adding capabilities to XIV in a extremely brief period of time since we acquired it," talked about David Vaughn, IBM's suggestions infrastructure platform manager. "Asynchronous mirroring is a huge step to complete the most important necessities for our consumers."
New twin processor modules provide the XIV Storage gadget up to 30% efficiency improvement, Vaughn spoke of. XIV also now has an SMI-S interface for faraway administration of IBM's Tivoli software and an LDAP interface. furthermore, IBM is giving customers a call between a one-yr and three-year base assurance for the XIV Storage system. It up to now provided a one-year base warranty and shoppers might add extra years.
IBM introduced a 27 TB entry-degree XIV Storage device version earlier this yr, however hasn't long past beyond a hundred and eighty TB. Vaughn stated the XIV structure will permit it to head past one hundred eighty TB, "nevertheless it doesn't scale that excessive yet." He additionally said mainframe help for XIV is on the roadmap, but "there's nothing imminent."
As is the case with IBM storage rival EMC, there has been confusion in the industry about the place the strains are drawn with IBM's systems. IBM considers the DS8000 and the XIV Storage equipment business systems however they're distinct architectures. How does an organization understand if it is going to believe a DS8000 or an XIV?
"If we're coping with somebody who's a DS8000 consumer today, we predict them to buy the DS8000 as a result of they've standardized with it and are at ease with it," Vaughn noted. "If we go into a new account, we might delivery the dialog with the DS8000 if or not it's a mainframe account. If the account is completely open programs, we would birth with the XIV."
Analysts noted the newest upgrades are imperative for business-grade storage programs. "if you are going to call it [XIV] an business gadget, the expectation is that every one these items is there," mentioned Arun Taneja, founder and consulting analyst at Hopkinton, Mass.-primarily based Taneja group. "In an incredible condition, a vendor would have all this functionality from day one, however how do you do that? What they introduced out remaining year with XIV turned into a first volley."
"it be now not like they may be the primary with these elements," spoke of Mark Peters, an analyst at Milford, Mass.-primarily based enterprise strategy group. He does not are expecting customers to buy programs in line with which have the superior skinny provisioning, but they do predict commercial enterprise systems to have it.
As for IBM's product positioning, Peters noted it could confuse purchasers, but "it's far enhanced to have an overlap in items than a hole. americans ask the equal query with EMC [with Clariion and Symmetrix platforms] about which equipment to buy, and in each instances the reply that comes lower back is 'mainframe.' Mainframe assist is the main difference, and one equipment is a scintilla more authentic than the other."
IBM's timing with thin provisioning is rarely fantastic. Its announcement comes a day after EMC spoke of it will present thin provisioning for free with its Symmetrix systems. IBM is charging at the least $69,000 to turn on thin provisioning for its DS8000 methods.
still, IBM's Vaughn stated thin provisioning is a money-saver because "you get a whole lot improved utilization of your disks."
skinny provisioning for the DS8000 and dual processors for the XIV Storage system could be available subsequent month, with the XIV's asynchronous mirroring due later within the 12 months.

-- IBM is now providing nine distinctive data administration utility equipment for managing and moving information in tiered storage environments with strong-state disk (SSD) drives.
The business's portfolio contains a collection of application tools that handle the migration, monitoring and dynamic placement of data on SSDs.
The equipment consist of "wise records placement" know-how in the type of IBM's information Facility Storage administration Subsystem (DFSMS) for zSeries and DS8000 environments. For its power techniques servers, IBM now presents SSD information Balancer tools that allow administrators to movement generally accessed information to SSDs, whereas moving occasionally accessed information to normal complicated drives.
On the hardware front, IBM additionally accelerated its use of SSDs to encompass vigour programs, joining gadget x servers and equipment Storage DS8000 gadgets, which already offer SSDs.
SSDs might be supported on all POWER6 programs, from Blades to enterprise servers, in addition to on the system x lineup of diskless pressure options with new SATA-vogue SSDs. A 50GB pressure, designed for larger I/O performance, is obtainable in either a 2.5-inch or 3.5-inch kind ingredient for blades and device x rack and tower servers. The SSDs help windows, Linux, and ESX Server.
IBM additionally invested in integrating DS8000 storage methods with servers and application to maximise the efficiency advantage of SSDs. The integrated solution will enable users to optimize the hybrid ambiance with SSDs and HDDs.
Mike Desens, IBM's vice chairman of equipment design, says the company's strategy to SSDs acknowledges that most clients could have hybrid storage environments that use high-speed SSDs in tandem with HDDs.
"we now have been enabling [the use of SSDs] across all of our hardware, working device and application structures in an effort to assist shoppers utilize SSDs within the right ways and to get facts onto the correct tier of storage," says Desens.
He says flash-primarily based SSD drives have the expertise to revolutionize the industry, however costs still deserve to come down.
"SSDs are going to have a big impact on the industry as fees continue to come back down at a quicker tempo than common HDDs and we see more capacity," says Desens.
IBM is the usage of two different types of single-stage cell (SLC) SSDs, including drives from STEC and Fusion-io. Desens says IBM is engaged on the way to use greater potential multi-degree cell (MLC) know-how.
"SLC technology is legit via put on-leveling, over provisioning and blunder correction technologies, but MLC still needs greater work and innovation to deliver it into enterprise-category purposes," he says.

IBM has launched a new set of solutions designed to tackle the challenges of improving security, managing and analysing vast amounts of data, cloud-computing utility and mainframe technologies billed as a new addition to the enterprise Power Systems family.
Spending over $1.4 billion on research and development per annum, IBM has developed its enterprise Power Systems with new hardware and software innovations designed to help customers gain business insights fast and securely.
The System and Technology Group Manager at IBM Egypt Ahmed Bourham said “this announcement reflects the continued focus of IBM on smarter computing systems, aimed at solving the varied and intensifying challenges organisations are facing.”
Power 770 and Power 780 servers now the feature Power7+ microprocessor, offering a performance boost of 30 to 40 per cent on application workloads compared to previous issues; at the top of the Power line, the Power 795 server has been enhanced to enable customers to run very demanding applications, such as business analytics.
IBM has added several new capabilities to its family of Power Systems servers, dubbed the Elastic Capacity on Demand for Power Systems Pools, in order to enable the sharing of resources across multiple servers.
“When managing a cloud-based infrastructure with IBM PowerVM virtualisation software, customers can now more easily move individual server partitions to quickly balance resources in reaction to changing business needs. Single virtual machines can be moved three times faster and concurrent migrations can occur up to 4.7 times faster than with previous versions,” IBM said in a statement.
The average corporate IT infrastructure is cyber-attacked nearly 60,000 times every day and the average total organisational cost of a data breach is $5.5 million, making security one of the top priorities of enterprise organisations.
On the other hand, IT managers have been facing continuous dynamic challenges because of the massive data volumes, which do not only stress system performance and manageability, but also affects security as well.
The IBM System Storage DS8870 is the newest member of the company’s DS8000 family of “high-density” enterprise class storage systems; it delivers up to three times more performance for transaction processing applications than the current DS8800 model.
IBM also had updated the IBM Virtualisation Engine TS7700 Release 3, which is a system that melds virtualisation with magnetic tape; this system is an update of the TS7700 Enterprise Virtual Tape Library System.
The new solution of Big Data Technical Computing includes IBM’s General Parallel File System (GPFS), an advanced file management platform often used in high performance computing environments for storing and delivering large volumes of data for weather modelling, oil exploration and digital media production.
Moreover, IBM announced software offerings for IBM’s newest mainframe – the “zEnterprise EC12” which helps clients operate their IT more efficiently and make good use of critical information to extract statistical data concerning their activities, and to provide better service to clients.
References to a mysterious IBM storage array are popping up across the web. Is this the hardware refresh of IBM's flagship DS8000 storage array line?
The first reference we spotted was from Freddie Sanchez, a firmware engineering guy at IBM in Arizona. His LinkedIn entry reads: "I develop and maintain embedded software for the enterprise high-performance IBM System Storage DS8700, DS8000 and DS6000 products. This includes system wide level debugging, architectural planning, iterative design, following established documentation procedures, implementation, unit test, and executing successful hardware integration."
Then there was a Bell Micro web page note about an IBM Business Partners' Enablement workshop - "DS8000 Technical update: Last announcements (R4.2) and Roadmap (DS8700)" - held yesterday at IBM Warwick, and given by Dominique Salomon from IBM's Product Solutions and Support Center in Montpellier.
Lastly we found an internal IBM bug report: "DS8700 systems with more than 170 GB memory may experience missing or corrupted memory."
We know IBM has DS8100 and 8300 systems in its flagship DS8000 enterprise storage array product line, but there is no DS8700. We think the DS8700 is a new high-end DS8000, a hardware refresh, and we reckon it will use POWER6 processors.
The 8100 and 8300 both use POWER5+ processors with the 8100 using dual 2-way processors and the 8300 using dual 4-way ones. POWER5+ is old hat in processing engine terms, having been succeeded by POWER6 and POWER 6+. POWER6 added decimal math and vectors and better threads to the microprocessor and POWER6+ added a few more tweaks and higher clock speeds.
Our information is that the p550 with four Power5+ cores running at 2.1 Ghz had a relative performance rating of 24.86. A p550 with four POWER6+ cores running at 4.2 Ghz is rated at 36.28 relative performance, and 52.24 with six cores, 46 per cent more oomph, core for core.
IBM has already starting phasing out the first generation POWER6 processors and is shipping POWER6+ systems. We can be fairly certain that a DS8700 will use at least POWER6 CPUs and possibly POWER6+. It may also increase the core count to get a greater boost in CPU horsepower for the new array and whatever software functions it's going to have. We don't know anything about them or any speeds and feeds data for the new box.
If the channel (Bell Micro) is being briefed now then we can expect a public announcement in the next few weeks. Following on from the introduction of thin provisioning for the DS8000 this should knock any ideas that the DS8000 is a dead array line on the head. Big Blue is most definitely still in the high-end enterprise array line. ®
Next version of z/VSE looks like an operating system reborn
IBM Corp.’s z/VSE operating environment is still going strong. Although z/VSE doesn’t boast much in the way of market share or revenue growth—not, at least, when compared to other, sexier System z workloads, such as Linux or zSeries Integrated Information Processor—Big Blue continues to invest in and improve the z/VSE experience.
If ongoing technology investment and new operating system revisions are positive indications of a platform’s viability, z/VSE looks as viable as ever.
Consider IBM’s upcoming z/VSE 4.2 release, for example. While Big Blue has been slow to introduce support for Linux and other next-gen workloads in previous iterations of z/VSE—at least relative to what it’s done with both z/VM and z/OS—the latest version of that venerable operating environment looks like VSE reborn, with better support for z/Linux, a new Encryption Facility, expanded storage support, and improved performance and scalability.
The rub, of course, is that customers will have to wait until late next year to get their hands on it: z/VSE 4.2 isn’t slated to ship until Q4 of 2008.
By the time it does ship, it could help fuel pent-up demand.
The impetus, IBM officials say, is the ever-increasing uptake of Big Iron Linux: as customers deploy more zLinux workloads on System z mainframes, they’re increasingly running them in conjunction with z/VSE applications.
For one thing, says Jerry Johnston, System z technical sales specialist and Boeblingen Lab senior advisor with IBM, the new release should make it easier for customers to expose their VSE applications to zLinux.
"There are a number of integration possibilities," he says. "Each customer is different. For example, four European customers presented solutions at the recent [Guide Share Europe] conference in Boeblingen. A couple of them have z/VSE applications that access data stored in DB2 UDB on Linux on System z. Another is working on WebSphere applications under Linux on System z that can access data stored in files on z/VSE."
There’s also HiperSockets, z/VM, and Integrated Facility for Linux (IFL) integration, too. "Customers can implement integrated solutions that exploit System z 'HiperSockets' for fast, secure communications between z/VSE and Linux on System z," he continues. "They can take advantage of low-cost IBM System z Integrated Facility for Linux (IFL) specialty engines. Last, but not least, customers can take advantage of IBM's world-class virtualization technology, z/VM, to get the most from their Linux on System z and z/VSE systems."
z/VSE 4.2 also eliminates a long-standing VSE bottleneck: a limit of 255 concurrent processes. In most cases, Johnston says, users have been able to work around this; once z/VSE 4.2 becomes generally available, they won’t have to. "The z/VSE operating system itself uses 32 of those [tasks]. Subsystems like CICS, VTAM, TCP/IP, DB2, [and so on] each use a number of tasks. They reduce the number of tasks available to the user for application programs," he explains. "z/VSE V4.2 users will have more than 255 tasks to work with. That means, for example, they can create more CICS and batch partitions in z/VSE V4.2. More partitions increase the ability of the system to do useful work, [which leads to] better scalability."
The new revision will also explode a traditional storage bottleneck, Johnston continues. True, z/VSE 4.1—which shipped earlier this year—eliminated the long-standing 2 GB central storage restriction (it boasted support for up to 8 GB of real storage), but z/VSE 4.2 will go that several orders of magnitude better.
"Now, z/VSE V4.2 is designed to support up to 32 GB … of real processor storage," he says, which could entail additional scalability benefits. "Larger real memory may lead to a reduction in paging. Paging occurs when a task needs central storage but no free storage is available. At that point, the operating system has to find a page to remove, transfer it to external page storage, and start the new activity. From a system point of view, paging is just wasted activity and to be avoided. z/VSE V4.2's support for up to 32 GB of real storage means that, in many cases, less paging will occur."
Finally, Johnston concludes, z/VSE 4.2 will ship with a new Encryption Facility to better secure business data. This is a more involved proposition than it might seem, he points out. For starters, the function of the new Encryption Facility for z/VSE V1.1 is roughly equivalent to that of the z/OS variant (also at version 1.1). This means both implementations are also interoperable. "Tapes created by one can be read by the other," Johnston says.
At all events, z/VSE’s new Encryption Facility will help protect against the accidental (and frequently quite literal) loss of data.
"You may have seen news stories about tapes that have been 'lost.' There have been articles about tapes that have been misplaced, stolen, dropped off the back of a delivery truck, taken from a truck while the driver was having coffee, etc.," he explains. "One solution to avoid the compromise of business/personal data is to encrypt the tape. … If a tape falls into the wrong hands, the information is safe because it cannot be read without knowing the key."
VSE’s new Encryption Facility will be packaged and licensed as an optional, priced feature of IBM’s VSE Central Functions version 8, according to Johnston. This product includes the basic VSE operating system, along with a passel of other features. As with z/OS, the Encryption Facility for z/VSE also exploits built-in System z features to accelerate encryption and reduce processing costs. "[Encryption Facility] for z/VSE exploits new System z hardware instructions designed to accelerate the encryption process. These instructions are part of a no-charge, optional hardware feature—available on z990/890, z9 EC, and z9 BC models—known as CP Assist for Cryptographic Function," Johnston indicates. "Similarly, when compressing data, [Encryption Facility] for z/VSE uses System z hardware compression instructions."
As an added bonus, it’ll also be eligible for the Midrange Workload License Charges pricing scheme that Big Blue introduced earlier this year.
