Freshly baked storage: Take a pinch of Intel Skylake silicon, some flash powder, sprinkle into IBM's FlashSystem

9100 and 9150 arrays slide out of the oven, added to line up


IBM today added new models to its FlashSystem line to more than double the family's maximum capacity, push performance higher with Intel Skylake processors, and strengthen its NVMe-over-fabrics capabilities.

There are two new systems on offer: the 9100 and the 9150. Both come in 2U enclosures with active:active controllers, and can scale out to eight nodes using four pairs. The 9100 uses eight-core Intel Sklyake CPUs while the 9150 gets 14-core processors. They both have up to 768GB of data cache per node.

The current 900 series, powered by Intel Broadwell CPUs, uses 32-layer 3D TLC NAND. We understand the 9100 line uses 64-layer 3D TLC NAND.

The arrays use two kinds of flash drives: IBM's own-design FlashCore Modules with 4.8TB, 9.6TB, and 19.2TB capacity, and commodity SSDs with 1.92TB, 3.84TB, 7.68TB and 15.36TB capacity levels.

The FlashCore Modules have NVMe interfaces that can be deployed with any combination of industry-standard NVMe flash drives. Both models can have a total of 480TB of raw capacity, and IBM says they feature:

  • NVMe optimization and NVMe-over-fabrics readiness
  • Deduplication
  • Hardware-assisted compression in the Flash modules, as with the current 900 product
  • Data Reduction pools add thin provisioning
  • 2PB effective capacity in 2U base box, scaling to 32PB in a 42U rack
  • RAID levels 1, 5 and 65
  • 16G fiber channel, 10Gbit/s iSCSI, 25GbitE iWARP and RoCE interfaces
  • Cloud tiering

The quoted effective capacity is the typical maximum amount of user data that can be stored after data reduction.

The 9150 runs up to 2.5 million IOPS, and 10 million IOPS in a 4-node cluster. The 900 series was rated at up to 1.2 million IOPS with up to 2.4 million IOPS achievable in the maximum configuration.

These FlashSystems come with a seven-year warranty. The FlashSystem 9100 and 9150 do not replace the existing 900, A9000 and A9000R systems, as these continue to be sold albeit with software different to that in the 9100.

Management is assisted via Storage Insights: IBM’s AI-based predictive analytics, storage resource management, and support platform delivered over the cloud.

The software environment includes Spectrum Virtualise, which virtualizes other IBM and third-party arrays to be managed as storage resources by the 9100s. It can also uses the IBM cloud.

Reference Architectures or blueprints

There are three pre-validated system blueprints:

  • Data Reuse, Protection and Efficiency - uses Spectrum Protect Plus and Spectrum Copy Data Management (CDM) to provide data protection for virtual applications with copy data management and reuse functionality both on premises and in the cloud,
  • Business Continuity and Data Reuse - uses Spectrum Virtualize for Public Cloud to extend data protection and disaster recovery capabilities to the IBM Cloud, and has the copy management and data reuse features of Spectrum CDM,
  • Private Cloud Flexibility and Data Protection - to deploy private clouds, with the technology needed to for container environments, and has Spectrum CDM to manage copy sprawl and provide data protection for containerised applications.

Battle cards

IT analyst house Evaluator Group prepared four battle cards comparing all-flash arrays from Dell EMC, HPE, NetApp, and Pure Storage against the FlashSystem 9100. These were accidentally slipped onto the open internet before IBM's big launch today.

These battle cards identify FlashSysytem 9100 strengths against these competing systems, but also the IBM product's weaknesses – areas in which IBM and its business partner sales people will have to defend the 9100.

After we clocked them in a Google search, the slides were pulled offline by Evaluator Group – however, they might return once the hardware's launch is out of the way on Tuesday.

The bottom line is: IBM is using Intel Skylake-powered controllers, and high-capacity flash drives, with an extended software environment, to provide two new FlashSystems ready for an NVMe-over-fabrics world. ®

    DuckDuckGo promises privacy to users of its Android, iOS browsers, and macOS browsers – yet it allows certain data to flow from third-party websites to Microsoft-owned services.

    Security researcher Zach Edwards recently conducted an audit of DuckDuckGo's mobile browsers and found that, contrary to expectations, they do not block Meta's Workplace domain, for example, from sending information to Microsoft's Bing and LinkedIn domains.

    Specifically, DuckDuckGo's software didn't stop Microsoft's trackers on the Workplace page from blabbing information about the user to Bing and LinkedIn for tailored advertising purposes. Other trackers, such as Google's, are blocked.

  • Despite 'key' partnership with AWS, Meta taps up Microsoft Azure for AI work
    Someone got Zuck'd

    Meta’s AI business unit set up shop in Microsoft Azure this week and announced a strategic partnership it says will advance PyTorch development on the public cloud.

    The deal [PDF] will see Mark Zuckerberg’s umbrella company deploy machine-learning workloads on thousands of Nvidia GPUs running in Azure. While a win for Microsoft, the partnership calls in to question just how strong Meta’s commitment to Amazon Web Services (AWS) really is.

    Back in those long-gone days of December, Meta named AWS as its “key long-term strategic cloud provider." As part of that, Meta promised that if it bought any companies that used AWS, it would continue to support their use of Amazon's cloud, rather than force them off into its own private datacenters. The pact also included a vow to expand Meta’s consumption of Amazon’s cloud-based compute, storage, database, and security services.

    IT services biz Atos has introduced a suite of cloud-based high-performance computing (HPC) services, based around technology gained from its purchase of cloud provider Nimbix last year.

    The Nimbix Supercomputing Suite is described by Atos as a set of flexible and secure HPC solutions available as a service. It includes access to HPC, AI, and quantum computing resources, according to the services company.

    In addition to the existing Nimbix HPC products, the updated portfolio includes a new federated supercomputing-as-a-service platform and a dedicated bare-metal service based on Atos BullSequana supercomputer hardware.
