When IBM designed the DS8870, it changed the bulk power supplies and batteries used in the previous DS8800 model to highly energy-efficient [DC-UPS]. In addition to reducing the overall energy consumption of the DS8870, it also gave the engineers space above the units to put 4U of standard 19-inch rack equipment.
The High Performance Flash Enclosure provides an ultra-dense and ultra-high-performance option. Each HPFE can delivers up to 250,000 IOPS and up to 3.4 GB/s bandwidth.
Up to thirty 387 GB Enterprise Multi-Level Cell (eMLC) flash cards provide up to 11.6 TB of raw capacity, about 9.2 TB usable, in only 1U of 19-inch rack space. A pair of very powerful integrated SAS RAID engines manage RAID-5 across the flash cards. The HPFE attaches directly to GX++ slots in the two DS8870 POWER7+ controllers, rather than using the Device Adapter (DA) loops.
You can have up to four of these HPFE in the "A" frame of your DS8870. Each HPFE can have either 16 or 30 flash cards. For 16 cards, you would have two spare plus two 6+P RAID-5 ranks. For 30 cards, you would add another two 6+P RAID-5 ranks.
Easy Tier Enhancements
Easy Tier is IBM's market-leading sub-volume automated tiering inside the DS8870 disk system. There were several enhancements in this announcement.
The first enhancement is to "Easy Tier Server", a feature that coordinates caching of active blocks of data inside the server's own internal Flash. This had supported Power Systems with EXP30 Ultra drawers, and now expanded to support IBM [Flash Adapter 90].
The second enhancement is to the three-level (Flash,Enterprise,Nearline) tiering algorithm. Inside the DS8870, the new HPFE flash cards will be part of the "Flash Tier" along with solid state drives (SSD) attached to the DA loops. Internal inter-tier load-balancing will take into account the faster nature of the flash cards in the HPFE, and move the busiest blocks accordingly. We we refer to this as "micro-tiering" within the Flash Tier.
Broader Solid State Drive options
Not everybody likes the 400GB solid state drives IBM offered for the DA loops, so IBM is now offering a smaller 200GB and a larger 800GB options as well.
Enhanced Concurrent Code Load
The new DS8870 R7.3 firmware release drastically cuts the activation time of concurrent code load in half.
Nobody likes warmstarts either. These are a necessary evil for some error conditions, but the clever engineers upstairs have figured out ways to reduce the number of warmstarts and eliminate the need to perform a warmstart after certain events to prevent any application impact to the attached host.
Multi-Target Remote Mirror
By now you know that IBM has the market-leading remote mirroring services for high-end disk systems, using less bandwidth and maintaining better concurrency than high-end systems from other vendors.
The DS8870 R7.2.7 firmware release can now support multi-target remote mirror. In previous releases, if you wanted three-site disaster recovery, you relied on Metro/Global Mirror, where site "A" had a Metro Mirror to a bunker site "B", and then site "B" had a Global Mirror to site "C". Not everybody liked this.
Some clients have asked for a "star" configuration, where "A"-to-"B" and "A"-to-"C" are independent of each other. A SCORE request is available for the following configurations:
Two Metro Mirror
One Metro Mirror and one Global Copy
Two Global Copy
While Metro Mirror can support up to 300km distance, and Global Copy can go any distance around the planet, there is no reason why you can't have one or both copies in the same building, or on campus nearby, for use with HyperSwap.
OpenStack Cinder interface support
Last but not least, the DS8870 now offers full support for OpenStack Havana and Icehouse releases. Support is provided through the OpenStack Cinder driver currently available for download. IBM is a platinum sponsor of the OpenStack foundation.
International Technology Group [ITG] has just published a series of papers about IBM SmartCloud Virtual Storage Center (VSC) and SAN Volume Controller/Storwize storage hypervisor virtualization technology detailing the cost benefit advantages over EMC and VMware.
IBM delivers up to 72% lower storage TCO than EMC storage virtualization and management solutions in large enterprises ... and up to 35% lower storage TCO than VMware tools in mid-sized environments
Also, you can watch an interview with the study's author, International Technology Group Managing Director, Brian Jeffery, live from next week's IBM Edge Conference in Las Vegas. Brian will be interviewed on [TheCUBE by Wikibon] on Monday afternoon. Watch it live on May 19!
I will be at Edge next week. If you plan to be there, I would be glad to discuss these ITG findings with you and your clients in person.
Jamie Thomas, IBM General Manager of Storage and Software Defined Environments
Jamie announced [IBM Elastic Storage], a new offering that is available as a software defined storage solution, based on IBM's General Parallel File System (GPFS) technology already deployed at 45,000 installations.
IBM Elastic Storage provides a global name view across data center locations. It can manage up to a Yotabyte of information, combining Flash, disk and tape resources. It supports OpenStack interfaces, Hadoop and standard POSIX file system conventions.
IBM Elastic Storage provides automated tiering to move data from different storage media types. Infrequently accessed files can be migrated to tape and automatically recalled back to disk when required. Unlike traditional storage, it allows you to smoothly grow or shrink your storage infrastructure without application disruption or outages.
IBM Elastic Storage software can run on a cluster of x86 and/or POWER-based servers, and can be used with internal disk, commodity storage, or advanced storage systems from IBM or other vendors.
IBM partnered with various clients in different industries in a special beta program. Jamie led a client panel to discuss their experiences with IBM Elastic Storage:
Alan Malek, Director of IT, Cypress Semiconductor.
"Total cycle time is key". Over the past 31 years, they bought whatever file storage was available. Now, with IBM Elastic Storage, the performance was very consistent for their engineering workloads with full load balancing.
Russell Schneider, Principal Storage Consultant, Jeskell.
Russell's company works with a lot of federal agencies, "Big Data has become Bigger Data". For example, research on Global Warming and Climate Change requires a large amount of storage across agencies.
In another example, when the tsunami hit Japan a few years ago, an agency here in the USA realized they had 14PB of data stored as a single copy in a data center at sea level less than a mile from the coast. They realized they needed to have a secondary copy, and an option to cache to a third location depending on regional disasters.
Matthew Richards, Products, OwnCloud.
For those not familiar with OwnCloud, it provides a Dropbox-like file sharing service, but in the Enterprise, with on-premise storage. It has been fully tested and certified with IBM Elastic Storage to provide a secure file sharing platform.
With IBM Elastic Storage, they were able to scale linearly up to 20,000 users, and are now testing 100,000 users. The need to have intelligent access to files at scale is what Matthew likes about IBM Elastic Storage.
Dr. Michael Factor, IBM Distinguished Engineer at IBM Research
Michael started out explaining there are three areas for storage: block, file and object. The fastest growing type of data is unstructured fixed content with associated metadata. This is ideal for object storage. Michael has been working with OpenStack Swift, an open source interface defined for object storage. He defined "storlets" as follows:
Storlets extend an object store by moving computation to the data -- filtering, transforming, analyzing -- instead of bringing data to the computation.
Storlets have been deployed on a variety of European Union research projects. For example, in partnership with Phillips, a pathology storlet can count the number of cancer cells in an image. By bringing the computation to the data, it eliminates having to transfer large amounts of data over the network.
Storlets can run on-premise and on IBM's SoftLayer IaaS cloud offering.
Bruce Hillsberg, IBM Director of Storage Systems at IBM Research
Bruce led another panel discussion, this time of IBM storage experts:
Vincent Hsu, IBM Fellow and CTO of Storage.
The problem is the isolation of data into "storage silos". Isolation causes problems in managing large amounts of data at scale, and costs more as storage is not fully utilized. IBM Elastic Storage brings everything together, eliminating storage silos.
Michael explained how IBM works with clients all over the world to ensure that storage solutions meet client requirements. For example, storlets can be used to use rich metadata to manage photographs, and display them based on GPS satellite location, or other content that makes it easier to manage these images.
IBM Elastic Storage will support OpenStack Cinder and Swift interfaces. IBM is a platinum sponsor of OpenStack foundation, and is now its second most prolific contributor, with hundreds of full-time employees working on this.
Tom Clark, IBM Distinguished Engineer, Chief Architect, Storage Software, Cloud & Smarter Infrastructure.
Storage Management is a critical piece of Software Defined Storage. This is done in three ways:
The use of analytics to optimize the deployment of storage, based on workload requirements. Storage admins set policies, and then IBM Elastic Storage analytics gather metrics and then optimize data placement and movement based on these policies. IBM Elastic Storage has 70 percent lower TCO that competitive offerings.
The focus on backup services. Backups are not just for data protection, but rather can be used to duplicate or replicate data for testing, for training, and for other purposes. IBM Elastic Storage is fully supported by IBM Tivoli Storage Manager.
Being able to support Hybrid Cloud environments, where some data can be on-premise, and other data off-premise. Storage Management challenges will need to deal with this possibility. IBM Elastic Storage is well positioned for this.
Carl Kraenzel, IBM Distinguished Engineer, Director of Watson Cloud Technology and Support.
Watson is ground-breaking technology, and IBM Elastic Storage technology was at the heart of the Watson that was first introduced in 2011.
To consider IBM Elastic Storage based on lower-cost and higher-scalability is not the full picture. Rather, this is an important platform for Cognitive Computing, which we are just at the tip of the iceberg in exploring. IT systems need to be aware of the context of what we are doing.
While the Grand Challenge demonstration on Jeopardy! was exciting, it is time we stop playing games and apply IBM Elastic Storage to business, to help with health care and medical research, and other problems in society. IBM has already deployed this at Anderson Cancer Center and Memorial Sloan Kettering Cancer Center, for example.
Tom Rosamilia provided closing remarks. IBM Elastic Storage is not just for new workloads in Cloud, Analytics, Mobile and Social (CAMS) but also traditional workloads as well. IBM Elastic Storage provides "data democracy" and allows for "better rested storage administrators" that make fewer mistakes.
Tom opened the floor for questions from the audience:
Q1. Data integrity, not just security but also quality? IBM Elastic Storage has end-to-end data integrity checking built-in.
Q2. How does IT transition from full control to auto-pilot? IBM allows you to tap into existing storage. This is not rip-and-replace. With storage virtualization, IBM hides the complexity that normally requires full control over specific assets.
Q3. Storage admins would rather have a root canal without Novocaine than move their data. What is IBM doing to offer automation to help storage admins move to this new infrastructure? IBM storage virtualization breaks that hard link between applications and specific storage devices. IBM Elastic Storage eliminates application downtime previously associated with data movement.
Tom Rosamilia assured the audience that IBM is fully committed to its storage portfolio. IBM Elastic Storage is not just about the profoundness of what IBM announced today, but also where IBM is investing in the future of storage.
Marking the occasion, here is an important letter from our Vice President, Laura Guio:
May 6, 2014
To Whom it may concern
Subject: ProtecTIER Development Update:
This year marks the sixth anniversary of IBM's acquisition of Diligent Technology. Over the past six years IBM has emerged as a leader in enterprise class data deduplication. Our highly scalable, dual node hardware redundancy and gateway design are unique characteristics in the industry. IBM fundamentally believes in the importance of cost saving data deduplication technology and continues to enhance our solution, improve value and increase investment protection for our installed base.
First, it is important to note what IBM has done most recently. IBM is among the first to integrate flash technology along with deduplication to boost performance and lower cost. Integration of the IBM FlashSystem 840 for metadata was completed the day the system was publically announced. The speed of technology integration is a result of our flexible gateway design which simplifies technology adoption. It also is enabled by our global development team providing a 24x7 system design, product test and integration environment.
Secondly, IBM has recently released ProtecTIER Mainframe Edition which enables the same enterprise class deduplication capability now for IBM System z. Another distinctive feature of ProtecTIER is its ability to sustain high throughput for both read and write operations. Most deduplication methodologies have an inherent read performance penalty. Since mainframe tape operations are much more read intensive than distributed systems, we were one of the first to market with a practical deduplication offering for all mainframe tape applications.
That's just what we've done getting out of the starting blocks in 2014. Our development team continues to enhance ProtecTIER. We're also working on refreshing the entire ProtecTIER product line with new model enhancements. A new gateway design is underway which will improve performance of the existing DD5. We expect this to be available as an upgrade, providing investment protection for existing ProtecTIER clients. The SM2 product family is also being redesigned to extend its capacity range. Along with hardware changes, we will widen the disk support matrix offering enhanced flexibility and new levels of price performance.*1*
We expect 2014 to be a busy year for IBM deduplication. We have development facilities around the world in Europe, North America, Central America and Asia, working on ProtecTIER. IBM continues to market, sell, and support ProtecTIER as our strategic offering for cost-reducing deduplication technology. Any suggestion that ProtecTIER is fading away is wishful thinking by our competitors. We are working to expand our markets as we have demonstrated by our recent introduction of ProtecTIER into the mainframe. Furthermore, we are looking to expand the use cases for ProtecTIER, which can now be attached as a NAS file system, to other areas besides pure backup. We're excited about what we are delivering today and where we can provide leadership by leveraging deduplication for customer storage environments.
