This week, I am presenting at the IBM Systems Technical University for Storage and POWER Systems. This conference is being held in New Orleans, Louisiana, October 16-20, 2017, at the beautiful Hyatt Regency.
Storage: Opening Keynote Session
Clod Barrera, IBM Distinguished Engineer and Chief Technical Strategist, and Craig Nelson, Brocade, co-presented this session.
Clod Barrera presented the latest in Storage trends. He organized his talk around four layers: Infrastructure, Storage Management, Storage Systems, and Storage Media.
Craig Nelson presented the changes in Storage Networking. With advancements in both server and storage bandwidth, the storage network becomes the bottleneck. Insane flash storage performance requires insanely fast storage networks. IBM offers Brocade-manufactured switches and directors that now support 32Gbps. Combining four paths together, these can offer Interswitch Connection Links (ICL) at 128 Gbps.
The Seven Tiers of Business Continuity and Disaster Recovery
With the recent Hurricans Harvey, Irma, Jose, and Maria, my topic on Business Continuity and Disaster Recovery (BC/DR) was well attended. I have been working in BC/DR for most of my career, including the "High Availability Center of Competency" or HACOC.
Back in 2005, I was here in New Orleans, the week before Hurricane Katrina, for the IBM Storage Symposium, August 22-26, the predecessor of this conference. I left on Friday, August 26, and the storm hit that weekend.
I met with people photographing all the buildings, in hopes to sell "before pictures" to insurance companies and filmmakers after the hurricane hit. Film director Spike Lee bought much of this footage. Smart!
However, natural disasters like hurricanes, tornados and floods represent less than 20 percent of all discasters. The majority of disasters, nearly 75 percent, arise from electrical power outages, human error, system failure and randsomware.
IBM FlashSystem Overview
Andy Walls, IBM Fellow, CTO and Chief Architect,and Brent Yardley, IBM STSM and Master Inventor, co-presented this session. Andy started with FlashSystem 900, V9000 and A9000/R.
The room was packed with standing room only, and Andy was answering so many questions that he never finished his portion, and Brent Yardley never had a chance to cover his portion.
Fortunately, there were "deep dive" sessions on FlashSystem 900, V9000 and A9000/R later in the week, so Andy suggested everyone go to lunch and attend these other more detailed sessions.
The new TS1155 enterprise tape drive can write up to 15 TB uncompressed data to existing JD/JZ/JL media.
It can read/write existing 10TB-formatted JD media, and 7TB-formatted JC media, written by former TS1150 drives. It also can offer read-only support for older 4TB-formatted JC media from TS1140 drives.
These are uncompressed capacities, and some clients achieve 2x or 3x compression on top of these capacities. This depends heavily on the type of data. Your mileage may vary, as they say.
Most of the rest of the features of the TS1150 drives carry forward., The performance 360 MB/sec is similar, encryption via IBM Security Key Lifecycle Manager (SKLM) is similar, and support for IBM Spectrum Archive via Linear Tape File System (LTFS) format is similar.
An interesting development is that the TS1155, in addition to standard 8Gb Fibre Channel attach, is the first IBM enterprise drive to also offer 10Gb Ethernet support. IBM will offer both RDMA over Converged Ethernet (RoCE) as well as iSCSI support.
The newest member of the IBM Spectrum Storage software family, IBM Spectrum Copy Data Management automates the creation of snapshot images (FlashCopy for those familiar with IBM terminology) on IBM, NetApp and EMC storage arrays. These copies can be made for various uses, such as DevOps, Dev/Test, Backup/Restore, and Disaster Recovery.
At some data centers, these copies can consume as much as 60 percent of your total storage space, because often each developer and tester are generating their own copies. Instead, having copies automated, registered, cataloged, and made available to developers and testers eliminates rogue copies.
This release adds support for additional databases, including Microsoft SQL Server on physical machines, SAP HANA in-memory databases, and Epic/Caché from InterSystems used in Electronic Health Records (EHR) management systems.
IBM also adds support for long-distance Vmotion for VMware virtual machine images. The target for this movement is IBM Spectrum Accelerate running on IBM Bluemix Cloud, supporting Hybrid Cloud configurations.
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.
Fellow blogger Chris Mellor from The Register has an interesting post titled [It's a ratchet: Old storage guard face incoming tech squeeze]. Chris opines that the big traditional storage vendors -- which he refers to as the "old guard": Dell EMC, HDS, HPE, IBM and NetApp -- are being squeezed out by startups with new technologies.
Last week, I saw the play [Fiddler on the Roof], a musical production by Arizona Theater Company (ATC), and thought of various parallels with Chris's post.
For those not familiar, the story centers around a father named Tevye and his wife trying to stick to tradition, with five daughters who are open to breaking with tradition to get married. The family lives in a small rural town, back in a time long ago when people were persecuted for their religious and ethnic background. Aren't you glad we live in [more enlightened times]!
Back to Chris Mellor, he writes in his post:
"This old guard has so far failed to squash newcomers in the all-flash array, hyperscale, object and software-defined storage areas. This is despite the established firms adopting these technologies and acquiring some startups."
Should the old guard try to squash newcomers? Often, these startups provide much needed innovations that move the IT industry forward.
In the play, Tevye wants to stick to tradition, whereby the town's matchmaker would find a husband for each daughter, and he, as father of each bride, would then provide his permission and blessing to the match.
Obviously, these startups are neither asking the old guard for their permission nor their blessing. While I can't speak for the rest of the "old guard", IBM is leading in these various spaces. Let's look at each of these new trends.
All-Flash Arrays (AFA)
The category of "All-Flash Arrays" include both purpose-built hardware as well as traditional devices based on solid-state drives (SSD). While the R&D investment needed for purpose-built hardware can limit this to some of the largest vendors, nearly any startup can slap commodity SSD into traditional HDD controllers and call it AFA.
IBM offers the world's fastest AFA, and has been a leader in the AFA category for the past three years, investing over $1 Billion USD on its FlashSystem, DS8000, Elastic Storage Server (ESS), SVC and Storwize product families.
Software-Defined Storage (SDS)
While the definition for SDS is still in a bit of flux, IDC has tried to identify three characteristics:
Storage software stack that can be installed on commodity resources (x86 hardware, hypervisors, or cloud) and/or off-the-shelf computing hardware
SDS should offer a full suite of storage services
Federation between the underlying persistent data placement resources to enable data mobility of its tenants between these resources
IBM has been ranked [Number 1 in Software Defined Storage] for several years now, investing over $1 Billion USD in its IBM Spectrum Storage family. This collection of software is implemented in a variety of offerings, including pre-built systems, software that you can deploy on commodity off-the-shelf servers, and in the Cloud.
Object storage breaks tradition with block and file-based storage solutions. Rather than reading and writing files using POSIX, NFS or SMB protocols, objects are accessed via HTTP GET and PUT requests. The two most common protocols are Amazon S3 and OpenStack Swift.
Object storage is ideal for static and stable data that either never changes, or changes infrequently. A lot of new workloads are based on unstructured data that falls in this category, such as Big Data Analytics, High-performance Computing (HPC), and active archives.
In the latest IDC Marketscape, [IBM is ranked #1 in Object Storage]. IBM has actually three software-defined storage offerings that support Object access methods. IBM Spectrum Scale, IBM Spectrum Archive and IBM Cloud Object storage System. The latter from 2015 acquisition of Cleversafe.
"Hyperscale leverages commodity servers and a software-defined approach, scaling the resources needed for applications and storage separately. As storage needs grow, companies can add servers running software-defined storage (SDS) to the storage tier to expand capacity... Data is automatically distributed across the entire cluster of storage servers as new nodes are added to the system... With hyperscale, .. cluster nodes network together to form a storage resource pool."
This breaks from the tradition of dual-controller high-end arrays, which scale-up, rather than scale-out. IBM offers its IBM Spectrum Accelerate, IBM Spectrum Scale, and IBM Cloud Object Storage System to fill this hyperscale requirement.
In the play, Tevye realizes the world is changing all around him, he can either fight these changes and stick to tradition, or accept that he must change also, and move on. After 105 years, IBM continues to lead the IT industry, primarily by adopting new trends and technologies, moving to new business opportunities as they present themselves.
Want to hear the latest technical information about IBM Storage, but not willing to wait until the big [IBM Edge Conference] this September?
I just completed two "IBM Tech University Comes to You" events. Last week in Atlanta, and this week in Dubai, UAE. In May and June, I will be speaking at the following events:
San Francisco, CA -- May 10-12
Chicago, IL -- May 18-20
Boston, MA -- June 7-9
Standard tuition rate for these 3-day events is $1,495. However, for my blog readers, I have negotiated two special discounts:
Individual: Promo Code TUST8R
The promotion code TUST8R for a $1,250 rate must be entered at enrollment to apply. This promotion code is only valid for the IBM Technical University (IBMTechU) Comes to You events in the United States found at [ibm.com/training/events].
Groups: Three or More
If THREE(3) co-workers attend the same event, each pays only $1,100 on tuition! This offer is only valid for the IBM Technical University (IBMTechU) Comes to You events in the United States found at [ibm.com/training/events]. The three-or-more attend for $1,100 promotion will be applied once validation is completed.
(The fine print: IBMTechU Comes to You events promotions (including currency OR pricing references which exclude applicable taxes) are current as of the initial date of publication of this blog and may be changed by IBM at any time. Discounts cannot be combined with any other programs or discounts, including IBM Business Partner discounts. Attendees will be charged the conference fees less any applicable discount. Any discount will be applied when the credit card is billed. All registrations require that credit card information is entered regardless of the payment type.)
Johann Weiss, Jim Blue and I joined several other local experts to answer questions and respond to comments and suggestions attendees had about IBM System Storage products and solutions. Here is a sample:
I would like to add 1TB of Flash to our FlashSystem 810 and have the system automatically re-stripe across this new capacity non-disruptively?
How can I have XIV systems at two datacenters in an active/active configuration that would allow me to vMotion from one location to the other non-disruptively?
Put them behind the SAN Volume Controller in Stretched Cluster mode.
What about a similar active/active but for NAS?
IBM N series.
I would like HyperSwap on the SVC/Storwize family like the DS8000 offers for AIX?
When will IBM offer a multi-frame XIV?
The "Hyper-Scale" set of features lets you logically connect 144 XIV frames together and treat as a single system. There is no need to physically bolt them together, since the communication is done over standard network switches.
When will IBM devices have native FCoE support?
All IBM System Storage products work within an FCoE framework today, either with native FCoE support, or through Top-of-Rack switches splitting out the traffic between IP and FCP traditional networks. IBM Storwize and N series products support FCoE natively, and any disk behind virtualized by SAN Volume Controller or Storwize can be access via FCoE hosts because of this support.
What is FLAPE?
FLAPE is the combination of Flash and Tape. Both of these technologies are improving over 40 percent year-to-year, but disk is slowing down to 20 percent improvement. It is possible to combine Flash and tape systems, such as IBM LTFS-EE or IBM ProtecTIER TS7600 series.
Only the Storwize V7000 Unified supports file modules to add NAS capabilities, what can IBM offer us that is smaller for NAS deployments, perhaps a Storwize V5000 Unified or Storwize V3700 Unified?
Consider the IBM N3000 series.
Other storage vendors indicate that RAID-5 and RAID-6 are running out of steam, are no longer practical to protect ever growing capacities of disk. What is IBM planning in this area?
IBM XIV Storage System was one of the first to offer a distributed RAID that addresses many of the RAID-5/RAID-6 drive rebuild concerns. IBM DCS3700 and DCS3860 also have Dynamic Disk Pooling to reduce drive rebuild impact. Lastly, IBM GPFS now offers Native RAID support, used in the IBM GPFS Storage Server.
Is it true that GPFS is NFS only?
Do not confuse GPFS the file system with the various storage offerings that are based on GPFS. IBM SONAS and Storwize V7000 Unified, both based on GPFS, support CIFS, NFS, HTTPS, SCP and FTP. IBM GPFS Storage Server can be configured to access GPFS natively, or you can run NFS v3/v4 server to make those protocols available. With Microsoft [Windows Storage Server], you can provide CIFS access to any GPFS-based storage solution.
LTFS-EE sounds like an exciting alternative to IBM Tivoli Storage Manager HSM space management for moving data from disk to tape. Do you agree?
Yes, we agree. However, TSM HSM space management supports a broader set of file systems. LTFS-EE only provides disk-to-tape movement for IBM GPFS.
Why does the DS8000 implementation of Easy Tier sub-LUN automated tiering support three tiers, but SVC/Storwize only support two tiers?
The same software engineering team works on both, but develop new features for the DS8000 first, get it working, then port it over to the Storwize family. At times, there might be gaps between what is supported on the latest DS8000 version and what is available on Storwize family products.
In an SVC Stretched Cluster, I would like to have the third quorum disk connected over the IP network, rather than FCP.
Personally, I enjoy these interchanges. They are sometimes called "Birds-of-a-Feather" or BOF at some conferences, "Free-for-All" at others. At IBM conferences, they are often titled "Meet the Experts". Whatever you call it, the questions and feedback on what clients are thinking are quite useful for product planning and prioritization of future planned features.
Last week, I was in Atlanta for the "IBM TechU Comes to You" event at the beautiful Marriott Marquis hotel. This was a three-day event, so here is my recap of Day 3.
Troubleshooting SAN Performance Issues
Jim Blue (IBM SAN Central) did a great job presenting best practices for resolving performance issues in your Storage Area Network (SAN). This was an advanced technical session intended for SAN administrators, with more level of detail than I am used to.
IBM's Cloud Storage Options
What do all IBM Storage products have in common? They can all be used in Cloud deployments. All of them. Really! No exceptions. I did a short 20-minute version of this in Las Vegas last February for InterConnect conference. Here in Atlanta, I expanded this to a full hour version.
(Whenever IBM Storage is sold into a Cloud deployment, IBM counts this as "IBM Cloud revenue" instead of "IBM Systems Storage revenue". Total IBM Cloud revenues (public,private and hybrid) for the first quarter of 2016 increased 34 percent--up 36 percent adjusting for currency--thanks to this clever way of counting money. See the [IBM 1Q 2016 Results] for more details.)
When I was first asked to cover "Cloud Storage", I asked "What do YOU mean by Cloud Storage?" as different people have different notions of what that is. Their response "You tell US what Cloud Storage is!" So, I came up with a four category taxonomy, and for each category, I explain which protocols of block, file or object provide the best fit, and which IBM Storage products we lead with in each area.
Optimizing Performance with IBM Spectrum Virtualize
IBM Spectrum Virtualize is the software that runs on IBM SAN Volume Controllers, Storwize, FlashSystem V9000, and all of these can be part of a VersaStack solution from IBM and Cisco. John Wilkinson from the IBM Hursley Lab that develops the IBM Spectrum Virtualize software gave a great presentation on how to optimize performance with these offerings.
A good part of his session was discussing the new "Distributed RAID" feature. Rather than having a dedicated SPARE drive that becomes a bottleneck during a RAID rebuild, the spare drive space is interspersed and rotated among all the drives, so that rebuilds can occur in parallel, much like the distributed RAID-10 in the IBM XIV storage system.
Using IBM Spectrum Control to manage IBM Spectrum Scale
Brian Sherman presented the latest synergy between Spectrum Control and Spectrum Scale, two products in our IBM Spectrum Storage family. In past releases, Spectrum Control was focused almost exclusively on SAN-based storage, with some support for IBM N series and NetApp filers. Now, IBM Spectrum Control provides a range of features to help manage IBM Spectrum Scale deployments, both at the file and object level.
At the end of the last day of this conference, people left early. Atlanta traffic is worse than Los Angeles or Boston. Rather than fly back home to Tucson, only to fly out again to Dubai, I stayed in Atlanta to fly directly to Dubai for my next speaking gig.
Did you miss Atlanta? Want to hear the latest technical information about IBM Storage, but not willing to wait until the big [IBM Edge Conference] this September? We will have several more "IBM TechU Comes to You" events in May and June. To learn more, or to register for one of these, check out the [IBM Technical Events in 2016] landing page. I have negotiated [special discounts] for those who read this blog!
Continuing coverage of the [Systems Technical University 2014] conference, we had an early morning awards ceremony to celebrate top sellers that led big wins in Europe for FlashSystems, XIV, Power Systems, and PureSystems.
Afterwards, there were several breakout sessions on day 2.
Storage Technology Futures -- fresh from IBM research labs, tomorrow in your datacenter
Axel Koester presented several projects from IBM Research labs that have contributed to actual products, including the incredible scalability of [PERCS] that was incorporated into IBM General Parallel File System (GPFS).
Cloud Storage and Active Cloud Engine
My presentation started off explaining the taxonomy of cloud storage. There are basically four kinds of cloud storage: persistent storage, ephemeral storage, hosted storage, and reference storage. Each of these has unique access patterns and service level requirements.
IBM has three distinct cloud storage offerings, so I covered IBM XIV Storage Systems, SONAS and Storwize V7000 Unified with Active Cloud Engine, and Linear Tape File System (LTFS) Enterprise Edition (LTFS-EE).
FlashSystem competitive overview
Henrik Wilken provided an excellent presentation comparing IBM FlashSystems to the dozen or more competitors that offer all-flash or hybrid flash-and-disk combinations.
IBM Tivoli Storage Productivity Center
From 2001 to 2003, I was the chief architect for what is now called Tivoli Storage Productivity Center. It continues to be the top most requested topic for briefings at the IBM Tucson Executive Briefing Center.
I presented an overview of Tivoli Storage Productivity Center, with a brief update on what's new in TPC 5.2.1 and the SmartCloud Virtual Storage Center v5.2.1 releases.
IBM Archive Storage Solutions - Data Retention for Government Compliance and Industry Regulations
I can't believe it has been nine years since I was on the Product Development Team for the IBM DR550 Data Retention storage solution!
In this session, I explained the lessons we learned from the DR550, its successor the Information Archive, and how we now position System Storage Archive Manager (SSAM) software as their replacement. SSAM was recently certified by KPMG to meet a variety of US, European and International laws.
Well it's Tuesday again, and you know what that means? IBM announcements!
(For those wondering where I went in July, then perhaps the better question should be "where didn't I go?". I started in Boston, MA, then Iceland, England, Hungary, Romania, Qatar, Kenya, Dubai UAE, and finally Seattle, WA. Whew! This week, I am visiting clients in Tennessee.)
Today, IBM launches a whole set of updated offerings based on the IBM Spectrum Virtualize software code base.
IBM Spectrum Virtualize v7.7.1 software-only offering
Like the rest of the IBM Spectrum Storage family of products, IBM Spectrum Virtualize can now be purchased as software only, allowing you to install it on your own x86 servers, rather than purchasing pre-built systems from IBM.
The software license comes in two flavors. The traditional "perpetual license" allows you to move the software from one x86 server to another. Say after 4 years, you have depreciated the server, or the hardware components fail, and you want to get a newer server. This is the same perpetual license that clients with IBM SAN Volume Controller and Storwize family have enjoyed since 2003.
The other is a "monthly license", which allows you to stand up your own "SVC" using your own x86 servers, for a period of months needed for a development/test project, disaster recovery, or some other purpose. After the project is over, you can discontinue the license, and re-purpose the x86 servers for something else. This is especially handy for Managed Service Providers (MSP) and Cloud Service Providers (CSP), but certainly can prove useful in traditional datacenters as well. The "monthly licensing" option is also available for IBM SAN Volume Controller (SVC) as well.
The software license is based on Tebibyte [TiB]. For those not familiar with international standards, here is a comparison table:
The v7.7.1 also provides new features for existing SVC, Storwize and FlashSystem V9000 products. Here are a few:
Manageability with CLI support for host groups
Scalability with support for up to 10,000 virtual disks, depending on the model; and up to 20 Expansion Enclosures on SVC 2145-DH8, Storwize 5639-SV1, FlashSystem V9000 models
RAS and performance enhancements for distributed RAID (DRAID)
Flexibility with iSCSI virtualization support for XIV® Gen 3, Spectrum Accelerate, FlashSystem A9000 and FlashSystem A9000R arrays.
The IBM SAN Volume Controller now offers "Enterprise Class Support" as an option. In the past, the SVC was a "customer setup" box, similar to midrange and entry-level products. Now, you can upgrade your support to match that of IBM DS8000 and XIV enterprise class offerings. This means that IBM experts will maintain your microcode levels for you.
The new 624 model is based on the 10-core [Intel Broadwell] processor, which IBM has clocked at up to 45 percent performance improvement. It also offers up to 128GB of cache memory per system, 64GB per node, double what came standard on the 524 model!
Why "Gen2+"? Moving from an 8-core Haswell to a 10-core Broadwell CPU, and doubling the cache memory didn't seem to be enough "architectural change" to justify calling in a "Gen3", so marketing decided on Gen2+ instead.
I refer to the IBM FlashSystem V9000 as my "Superman" product. When Superman dons on his glasses he becomes "Clark Kent", mild-mannered newspaper reporter. But behind the glasses, he is always Superman! Likewise, the FlashSystem V9000 is an all-flash array with an impressive set of features, but take off the fancy bezel, and you find that it is a pair of fully-loaded SAN Volume Controllers (which we call "Control Enclosures AC3") and a FlashSystem 900 drawer of the world's fastest flash storage.
The FlashSystem V9000 can attach up to 20 expansion enclosures over 12Gb SAS connections. Each expansion enclosure can hold either 24 of the smaller 2.5-inch drives, or 12 of the larger 3.5-inch drives. Of course, the FlashSystem V9000 can also virtualize any of almost 400 other storage arrays, similar to SAN Volume Controller. This provides tiering options that match well with the FlashSystem 900 inside using IBM's Easy Tier auto-tiering capability.
IBM Storwize V7000F and V5030F all-flash array models
The FlashSystem V9000 was originally going to be called the Storwize V9000, but the FlashSystem folks wanted to keep all of the "FlashCore" technology under one name. In perhaps a bit retaliation, or maybe sibling rivalry, the Storwize team added the letter "F" to refer to the All-flash models of the Storwize V7000F and V5030F.
The "flash" in the V7000F and V5030F are just Solid-state drives, not nearly as fast as the cards in the FlashSystem models. The drives come in 1.92TB and 3.84TB capacities. You might see these rounded up to 2TB and 4TB on some presentations, but IBM officially never likes to exaggerate.
This week, I presented at the "IBM TechU Comes to You" event in the beautiful [Kempinski hotel], part of the [Mall of the Emirates] on the famous Sheikh Zayed Road in Dubai, United Arab Emirates. This was a three-day event, so here is my recap of Day 1.
Marlin Maddy (IBM Systems Lab Services) acted as emcee to kick off this event. We had about 150 attendees. Louise Hemond-Wilson (IBM Distinguished Engineer) and Glenn Anderson (IBM Systems Lab services) presented similar to last week in Atlanta. See my blog post [Atlanta Day 1 Recap] for an overview.
Software Defined Storage - What is it, How can it help?
Mike Griese (IBM WW Spectrum Storage Software Evangelist) presented his viewpoint on Software Defined Storage. His focus was on what we call "software-based" or "software-deployed" storage solutions. These are solutions that are basically software deployed on industry-standard servers, such as x86 or OpenPower, that provide a choice of server vendor.
(In Atlanta, Clod Barrera, Jeff Barnett, and I presented back-to-back sessions on Software Defined Storage (SDS). See my blog post [Atlanta Day 1 Recap] for an overview of those three sessions.)
The key difference between "Software-Deployed" storage and "Software-Controlled" storage is that the former is ideal to reduce costs by using commodity, off-the-shelf servers, but may not have all of the OpenStack, VMware or Microsoft APIs needed to effectively manage the solution as part of a large data center or Cloud facility.
If, however, you are deploying Software-deployed storage in Remote Office/Branch Office locations, Test/Dev departments, or similar small deployments, that may not be an issue.
All Flash is not Equal -- Contrasting difference between IBM FlashSystem and SSD
This was a special request by the local UAE team, because many FlashSystem presentations focus on the product, but don't explain the underlying technology, specifically what differentiates IBM FlashSystem from substantially slower competitive alternatives like EMC XtremIO and PureStorage that are based instead on fallible commodity Solid State Drives (SSD).
By working closely with our chip vendor, Micron, IBM was able to improve the write endurance of these Multi-level cell (MLC) chips by 9.4x, and reduce write amplification by 45 percent.
I explained IBM's clever asymmetrical wear-level balancing, heat segregation, read disturb mitigation, voltage level shifting, and health binning, all of which contribute to the performance and reliability of this solution. IBM's innovative Error Correcting Code provides LDPC-like correction strength but at much faster BCH-like latency speed.
This was such a popular session that I have been asked to present again at the upcoming IBM TechU events in San Francisco, Chicago and Boston.
How to combine advantage of storage virtualization & Flash performance (Turbocompression effect)
Dominique Salomon (IBM Certified IT Specialist Storage from Montpelier, France) presented Turbocompression, the benefits of combining IBM Real-time Compression (RtC) with Easy Tier sub-volume automated tiering.
Sometimes two things just go well together. Chocolate and Peanut Butter, Bacon and Maple Syrup, Peaches and Cream, are just a few pairings that come to mind.
Initially, when IBM introduced RtC, it did not allow Easy Tier on the same compressed volumes, in an effort to avoid conflicts. Then in a later release, IBM lifted the restriction, allowing them to apply to the same volumes. The results were surprising, both benefit each other. IBM has taken this further, using Easy Tier information to enhance compression algorithms on an extent by extent basis.
The combination improves performance while reducing total cost of ownership, and is available on all of the latest Spectrum Virtualize products: SAN Volume Controller, Storwize V7000, Storwize V7000 Unified, Storwize V5000, FlashSystem V9000, as well as any of these in the VersaStack converged system from IBM and Cisco.
DS8880 IBM Newest Disk Storage System
Maurice "Mo" McCullough (IBM Lab Services and Training) presented the latest DS8000 models, the DS8884 and DS8886. IBM is number #1 in storage attached to the mainframe, with 42 percent marketshare, and this is because IBM's investment in this platform, beating out HDS, EMC and HPE.
Each country and culture is different, but in many of the Islamic countries, it is considered inappropriate to serve alcoholic drinks at the after-hours reception. Instead, we had our sponsors serve juice and coffee. IBM does business in over 170 countries, and I have been to nearly half of them, so we know how to adjust and adapt to each and every unique situation.
