IBM Tech University Dubai - Day 1 Recap
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.
Was Dubai too far away for you to attend? 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 upcoming events in the United States for those who read this blog!
