Well, it's Tuesday again, and you know what that means? IBM Announcements!
It has been 71 days since my last post, and people were beginning to worry. Did Tony with the lottery? Was Tony hit by a bus? Did Tony get abducted by aliens from another planet? No, none of these things happened.
I got a new job! I am still working with IBM Systems, but now am one of the Event Content Managers for the [IBM Systems Technical University] events, or TechU for short. For those who have attended these events, I have taken over for Glenn Anderson, who retired December 31, 2018.
Last year, the IBM TechU team asked me to present eight topics at an event in Johannesburg, South Africa, as a last-minute replacement for other speakers. While there, Glenn Anderson mentioned to me that he was planning to retire. "Do you know anyone interested in taking over for me?" he asked.
I jumped at the chance to apply for the job! There was stiff competition, but after three rounds of interviews and background checks, I was offered the position! This all happened after the zTechU event in Hollywood, Florida last October, so if this is the first you have heard of it, you are not alone.
For those wondering "What about the IBM Tucson Client Experience Center?" you have good reason to ask. I had worked at the center for the past 12 years, the last six as the chief subject matter expert (SME) for all things IBM System Storage. Who is going to replace me? The job posting is still open, and the new manager, John Zupetz, has been reviewing resumes.
As time permits, I will continue to do storage briefings to help out during this transition, both here in Tucson, Arizona, as well as outbound to various client and IBM locations. I have also offered to help train whomever gets hired for the job.
In my new role, I will be managing TechU events, selecting topics, accepting speakers, scheduling sessions, and even presenting sessions at the events themselves. I will be focused on IBM Z and LinuxONE mainframe servers and related Storage solutions, but will also manage sessions on soft skills for IT Leadership and Professional Development.
We plan to have about 18 events this year, spanning countries across six continents! I just finished smaller 3-day events in Istanbul, Turkey and Cairo, Egypt, and am now working on larger events to be held in Dubai, Atlanta, and Berlin!
Shameless plug! Registration is open for these TechU events. I plan to be at all three, if you want to meet me in person!
In the meantime, I have decided to take on two extra co-authors for this blog. Let me introduce them to you:
I have spent the last 10 weeks working with the IBM developerWorks team converting from a single-author blog to a multi-author blog. I had no idea it would be so complicated to re-work the HTML templates, acquire all the legal and managerial approvals, and then authorize additional contributors!
I look forward to working with my new co-authors!

Well, it's Tuesday again, and you know what that means? IBM Announcements! This week IBM announced new and refreshed storage products.
On Feb 20, there will be a [Live Stream event] to watch the announcements online. The event is at Half Moon Bay in California, starting at 9:30am Pacific Standard Time (PST).
IBM decided to do things a bit differently for this launch. Instead of dozens of stodgy press releases, IBM has opted to complement with a series of blog posts, with [Storage innovation drives 21st century business] providing an overall recap.
(FTC Disclosure: I work for IBM. This blog post can be considered a "paid celebrity endorsement")
Yes, this was a big launch! Send me your thoughts in the comments section below.

Well, it's Tuesday again, and you know what that means? IBM Announcements!
Today, IBM announces a complete refresh of its IBM FlashSystem® all-flash array product line.
(FCC Disclosure: I work for IBM. Compression, data footprint reduction, and performance results, based here on internal IBM tests, vary widely by data and workload type. Your mileage may vary. This blog post can be considered a "paid celebrity endorsement".)
I realize this is a lot to absorb, feel free to read this blog post over and over until it sinks in!

Tomorrow, I will be presenting at the STU Orlando for Storage and Cognitive Systems (formerly POWER servers). This conference will be held in New Orleans, Louisiana, October 16-20, 2017.
Here is my speaking schedule:
If these topics seem familiar, I have presented them at prior events earlier this year, including the STU Orlando in Orlando Florida, and the one in Melbourne Australia. However, I have made updates! New products have been announced!
If you are planning to attend, here are some of my past blog posts to help you get up to speed:
The STU at New Orleans will be a 5-day event. Instead of a "Meet the Experts" session, they are having a "Poster Session" in its place. Many of the posters will have QR codes, so make sure you have a "QR Scanner" application installed on your smartphone so you can scan them quickly!
Everyone, speakers and attendees alike, should consider making a QR code for themselves for this event. Go to [any number of websites] that generate a QR code. This could a VCF file with all of your contact information, a link to your blog or website, or point to your presentations on Slideshare or IBM@Box.
The next time someone at the event asks for this information, display the QR code on your smartphone, and let them scan it. Alternatively, you can send the image via MMS text message.
(My QR Code is fully functional, go ahead and practice scanning it with your smartphone for practice!)
I arrive in to New Orleans Sunday afternoon, so if you are in town, give me a shout! Or tweet me at @az990tony

I have been blogging for more than 10 years now, so I am no stranger to commenting on competitive comparisons. In some cases, I am setting the record straight, and other times, poking fun at competitor results, claims or conclusions. This comparison from Brian Carmody was too juicy to ignore.
(FCC Disclosure: I work for IBM. I have no financial interest in Infinidat, Dell EMC, nor Pure Storage, mentioned in this post. I do have friends and former co-workers who now work for Infinidat. This blog post can be considered a "paid celebrity endorsement" for IBM FlashSystem products.)
Fellow blogger Brian Carmody, formerly with IBM but now Chief Technology Officer at a startup called Infinidat, wrote [Flash is not Fast, and the Sky is Falling].
Here is an excerpt, I have added (Infinidat) wherever Brian says "we" just so there is no confusion:
"... So last week we (Infinidat) finally got around to running the same profiles against an INFINIDAT F6230 in our Waltham Solution Center, configured with 1.1TB of DDR-4 DRAM, 200TB TLC NAND, and 480 3TB Nearline HDDs.
In summary, we (Infinidat) wrecked the Pure and EMC systems. Here are the results side by side with EMC's data:<<
By the way, we (Infinidat) took the liberty of running the test with a 200TB data set instead of Pure and EMC's 50TB because modern workloads require performance at scale, and we ran it with in-line compression enabled because our compression algorithm doesn't hurt performance.
This was an interesting test to run, and we (Infinidat) hope it helps the storage industry move away from media type wars and benchmarks (you will lose every time on performance if INFINIDAT is in the mix) ..."
Notice anything wrong here? anything missing?
The Tortoise beat "Hare 1" and "Hare 2", but did not invite the Cheetah to the race?
Brian was smart enough not to compare their product to anything from IBM. IBM has a wide variety of All-Flash Arrays, including the DS8880F models, the Storwize V7000F and V5030F models, and Elastic Storage Server models. However, for this workload, IBM would probably recommend the FlashSystem V9000, A9000 or A9000R.
Any All-Flash Array with a steady-state latency of 2 milliseconds or greater is embarassing, but then Infinibox is not really an All-Flash Array.
The architecture of their Infinibox appears much like the original XIV. It has a mix of DRAM memory and SSD cache, combined with spinning drives. It offers only compression, not data deduplication. Unlike the IBM XIV powered by six to 15 servers, the Infinibox appears under-powered with just three servers.
The Infinibox uses software-based in-line compression, which must put a huge tax on the few CPUs they have in those three servers. Infinidat chose not to compress the data in their cache, probably to reduce the additional overhead on their over-taxed CPUs.
The IBM FlashSystem V9000 has an innovative design, based on IBM Spectrum Virtualize, the mature software that you also find in the IBM SAN Volume Controller and Storwize family of products.
The FlashSystem V9000 offers hard
IBM compresses its cache, using a two-tier approach. The "upper cache" receives the data uncompressed, so that it can then tell the application to continue, for fastest turn-around time. Then the data is compressed, and stored in the "lower cache", optimizing the value and benefits of DRAM memory. Many databases get up to 80 percent savings, resulting in a 5-to-1 benefit in DRAM cache memory.
The IBM FlashSystem A9000 and A9000R also have an innovative, based on IBM Spectrum Accelerate, the code originally developed for IBM XIV storage system.
(Fun fact: Infinidat's founder, [Moshe Yanai], was formerly the founder and designer of XIV, and it appears that Infinidat is just a re-design of old XIV technology architecture, re-packaged with a few differences. Since Moshe left, IBM has drastically enhanced the IBM XIV.)
Like the IBM Spectrum Virtualize family, the IBM FlashSystem A9000 and A9000R have hard
The IBM FlashSystem A9000 and A9000R also offer in-line data deduplication. Modern workloads are virtualized, and Virtual Machine (VM) and Virtual Desktop Infrastructure (VDI) get significant benefits from data deduplication. Infinidat does not play here. For the FlashSystem A9000, most of the metadata related to data deduplication is in cache, minimizing the overhead.
IBM FlashSystem A9000 and A9000R have full performance that blows these published Infinibox results away WITH compression and deduplication turned on.
Brian ran a workload that used the DRAM and SSD cache exclusively, eliminating the reality that any REAL WORLD workload would have to tap into those much slower spinning drives. This is not really a side-to-side benchmark. He is comparing his live run on Infinibox to published numbers from a previous comparison run on a completely different set of data.
This raises the question, why pay for all those spinning drives at all, if you plan to only use the DRAM and Flash storage for your workloads?
A week later, Brian followed up with another post [The INFINIDAT Challenge], acknowledging his comparison was bogus. Here's an excerpt. Again, I have added (Infinidat) wherever Brian is referring to his employer just so there is no confusion:
"... It's not likely that a room full of storage engineers will ever agree on parameters for a synthetic benchmark since storage evaluations are competitive and control of test parameters will invariably predetermine the 'winner'. However, I hope we can all agree that synthetic benchmarks are a waste of time, and that real world performance is what matters in the data center.
So, what can we (Infinidat) do about it?
We (Infinidat) cordially invite every enterprise storage customer who wants lower latency and lower storage cost to visit [Fas
Thanks again to all who participated in the dialog over the past week. I know the post generated some controversy. Traditional storage companies are fighting for their lives trying to keep enterprise storage expensive; indeed their business models are predicated upon maintaining price levels from a bygone era...."
As consolidation play doing full range of data services, I do not see this Infinibox working out. Talking to clients who have the Infinibox, the performance deteriorates in REAL WORLD workloads as you add more data to the unit.
The Infinibox seems fine for workloads that do not demand high performance, so I was surprised Brian compared it to All-Flash arrays. The Infinibox is out of its league!
(To be fair, Pure Storage and EMC XtremeIO aren't really in the same league as IBM FlashSystem, either, given that both of those products are based on commodity SSD. IBM FlashSystem models are consistently 4 to 10 times lower latency than these Commodity-SSD based competitors.)
The Infinibox also lacks features many people expect in an Enterprise-class storage array, like Call-Home capability to identify problems quickly, and Synchronous remote mirroring for disaster recovery. It is often common for startups like Infinidat to deliver a [Minimum Viable Product] as their first offering.
To paraphrase Brian himself, your applications will lose every time on performance if INFINIDAT is in your datacenter.
