IBM’s Strategic Initiatives Gain New All-Flash Storage

May 6, 2016

Flash storage must be the latest rage among enterprise storage vendors.  Last week IBM introduced three new all-flash storage arrays, driving down latency and price/gigabyte to unheard of levels (minimum latency of 250μs, all-flash storage as low as $1.50 per gigabyte). Earlier this week EMC announced new all-flash arrays for its Unity series at prices under $18,000 (under $10,000 for hybrid arrays.) Flash storage has long beaten hard disk in terms of cost per IOPS, but now it is rivaling hard disk in terms of cost/gigabyte.

OK, it looks a little—uh—boxy to say the least. But the new FlashSystem A9000 is packed with storage goodies. It comes fully configured, which helps drive down the cost of implementing an all-flash environment. Its sister, the FlashSystem A9000R, brings a grid architecture that provides for easy scaling up to the petabyte range. Both FlashSystems incorporate data reduction features, including pattern removal, deduplication and real-time compression, as well as IBM FlashCore technology to deliver consistent low latency performance. As noted above, they are priced as low as $1.50 per gigabyte.

Driving IBM’s latest interest in flash storage are its strategic initiatives, start with cloud computing. Consumers today, notes IBM, are demanding cloud-based applications that are fast, easy, and intelligent. That means minimal latency. Cloud users are demanding sub-second response times, especially when accessing critical data. They also are demanding cloud providers deliver a unique, personalized, and positive customer experience.

To deliver this, IBM is turning to hardware innovation, specifically its MicroLatency technology, to transfers data within the flash array instead of adding another layer of software. MicroLatency technology inserts FPGAs (hardware) that connects and communicates directly with the flash and RAID controllers, eliminating the latency of software and even firmware. Instead, the FlashSystems lets hardware talk directly with hardware.

In addition, IBM is packing the new FlashSystem arrays with features designed to solve cloud requirements such as quality-of-service (QoS) to prevent the noisy neighbor problems with application performance. The new arrays also feature secure multi-tenancy, thresholding, and easy-to-deploy grid scale-out capabilities.

The z System platform is not being ignored in all of this. IBM is including a new DS model, the all-flash IBM DS 8888 optimized for enterprise-class servers: With the all-flash IBM DS8888, customer databases and data-intensive applications are accelerated, resulting in improved business performance and customer satisfaction.

Specifically, the DS888 brings faster decision making and improve customer serviceability, with 4x performance over previous generations and accelerated response time for mission critical applications. The flash storage delivers up to 2.5 million IOPS, the result of having been built on the Power8 processor. It also enables organizations to streamline operations through the performance of an all flash architected solution aligned to provide the deepest integration with System z environments. For instance, IBM promises the most robust FICON connectivity through an architecture optimized for mainframe’s 4K cache segments.

In addition, the DS8888 promises 24×7 access to data and applications through superior business continuity on high demand transaction processing workloads while delivering top operations performance through its all flash architecture. It goes beyond the usual high end 5-nines availability to deliver 6-nines availability, which translates into a mere 2.59 seconds of downtime per month.  Other availability features include flexible replication (IBM FlashCopy, Metro Mirror, Global Mirror, Metro/Global Mirror, Global Copy & Multiple Target Peer-to-Peer Remote Copy). In the early years of flash reliability and availability were a concern.  With the DS8888 and 6-nines availability it isn’t any more.

Finally, it comes with a smorgasbord of security and efficiency goodies, including self-encrypted flash drives, key interoperability management protocol, syslog protocol, an intuitive GUI (IBM has learned a few tricks from Apple), innovative storage software licensing, RESTful and OpenStack APIs to connect workloads between private and public clouds, and thin provisioning for maximum utilization and reclamation of capacity from deleted data.

All-flash solutions announced last week complement IBM’s existing all-flash portfolio including FlashSystem 900 and V9000 that also leverage IBM’s FlashCore technology. IBM’s midrange all-flash solutions consist of all-flash versions of IBM’s Storwize family, which offers the performance needed for real-time insights from business data combined with advanced management functions. IBM’s Big Data all-flash solution delivers high-density multi-petabyte scale and a low-cost flash option ideal for industries such as media, genomics, and life sciences.

DancingDinosaur used to be hired to write papers around the enterprise cost-performance tradeoffs between hard disk and SSD/flash. No matter how expensive flash was at whatever point, the cost per IOPS always favored flash and cost per gigabytes always favored hard disk. That’s no longer an analysis worth even making today.

IBM Enhances the DS8000 Storage Family for New Challenges

October 30, 2015

Earlier this month IBM introduced a family of business-critical hybrid data storage systems that span a wide range of price points. The family is powered by the next generation of IBM’s proven DS8000 storage platform and delivers critical application acceleration, 6-nines (99.9999) availability, and industry-leading capabilities, like integrated high performance flash.  And coming along in November and December will be new tape storage products.

The company sees demand for the new storage being driven by cloud, mobile, analytics, and security. As IBM continues to encourage data centers to expand into new workloads, it is introducing a new family of business-critical hybrid flash data systems primarily to support the latest requirements of z System- and Power-based data centers. If your shop hasn’t started to experience a ramp up of new workloads it likely will soon enough.

The new storage family, all based on POWER8 and the DS8000 software stack, currently consists 3 models:

  1. The entry model, the DS8884, delivers fast hybrid flash starting at under $50K. It offers up to 12 cores, 256 GB total system memory, 64 16GB FCP/FICON ports, and 768 HDD/SSD + 120 Flash cards in a 19”, 40u rack.
  2. The DS8886 brings a 2x performance boost, up to 48 cores, 2 TB total system memory, 128 16GB FCP/FICON ports, and 1536 HDD/SSD’s + 240 Flash cards packed into a 19”, 46u rack.
  3. The high end DS8888, according to IBM, is the industry’s fastest T1 Subsystem. It offers all-flash with up to 96 cores, 2 TB total system memory, 128 16GB FCP/FICON ports, and 480 Flash cards packed in the 19”, 40u rack. Won’t be available until spring 2016.

Being built on the DS8000 software stack, the new storage brings unparalleled integration with IBM z System. The systems are especially tuned for insight and cloud environments. They also deliver top efficiency and maximum utilization of resources including staff productivity, space utilization and lower cost through streamlined operations and a 30% reduction in footprint vs. 33″-34” racks.

The DS8888 family comes with two license options: Base function license provides Logical Configuration support for FB, Original Equipment License (OEL), IBM Database Protection, Thin Provisioning, Encryption Authorization, Easy Tier, and I/O Priority Manager. The z Synergy Service  Function license brings PAV, and Hyper-PAV, FICON and High Performance FICON (zHPF), IBM z/OS Distributed Data Backup, and a range of Copy Services Functions including FlashCopy, Metro Mirror, Global MirrorMetro/Global Mirror, z/Global Mirror & z/Global Mirror Resync, and Multi-Target PPRC .

The DS8880 family also provides 99.9999% uptime, an increase over the typical industry uptime benchmark of 99.999% uptime. That extra decimal point translates into 365.243 continuous days of uptime per year. Even the most mission-critical application can probably live with that.

The High-Performance Flash Enclosure for the DS8880 family redefines what IBM considers true enterprise hybrid flash data systems should be, especially in terms of performance for critical applications. Usually, hybrid systems combine flash and traditional spinning drives to be deployed among a variety of mixed workloads of private or public clouds, while reserving more costly all-flash storage for delivering the most extreme performance for only those applications that require it. Now IBM recommends hybrid configurations for consolidation of virtually all workloads since the DS8880 preserves the flexibility to deliver flash performance exactly where and when it is needed automatically through Easy Tier, which optimizes application performance dynamically across any DS8880 configuration without requiring administrators to manually tune and retune applications and storage.

The DS8880 also supports a wide variety of enterprise server and virtual server platforms, but not all are created equal. It includes special integration with z Systems and IBM Power Systems. This is due to the advanced microcode that has been developed and enhanced in lockstep with the mainframe’s I/O architecture over the past several decades. For Power shops the DS8880 copy services are tightly integrated with IBM PowerHA SystemMirror for AIX and IBM i, which add another level of assurance for users who need 24×7 business continuity for their critical Power systems.

For shops dealing with VMware, the DS8880 includes interoperability with VMware vStorage APIs for Array Integration, VMware vCenter Site Recovery Manager, and a VMware vCenter plug-in that allows users to offload storage management operations in VMware environments to the DS8880. Should you prefer to go the other direction, the DS8880 supports IBM Storage Management Console for VMware vCenter to help VMware administrators independently monitor and control their storage resources from the VMware vSphere Client GUI.

If you didn’t notice, there have been a series of interesting announcements coming out of IBM Insight, which wrapped up yesterday in Las Vegas. DancingDinosaur intends to recap some of the most interesting announcements in case you missed them.
