Some job titles can be vague. Have you ever given your title to a person at a cocktail party, only to have to explain exactly what you do? With a title like "IBM Master Inventor and Senior Managing Consultant", this happens to me all the time. To help explain what we do at the Tucson Executive Briefing Center (EBC), I use the following analogy.
People who want to see or interact with animals have several options. One option is to go visit the animals in their natural habitat. A more convenient option, however, is to visit the animals in a zoo. Zoos bring together a wide variety of animals, making it convenient to visit all of them at one time.
I did not fully appreciate the advantage of zoos until I took a safari in Kenya, Africa a few years ago. The word safari means "long journey" in Swahili. For two weeks, we drove around in a Land Rover on bumpy roads across the country. The best time to see the animals was early in the morning and late in the afternoon. We would drive around for hours looking for a type animal we had not seen already. Most came to see the so-called "Big Five": Buffalo, Elephant, Leopard, Lion and Rhinoceros. After two weeks and hundreds of miles, we had seen the "Big Nine" which extends the Big Five to include the Cheetah, Zebra, Giraffe and Hippo, as well as seeing a variety of other, lesser known animals.
When it comes to zoos, there are two kinds.
Self-guided -- offering the basic zoo experience where you are handed a map to visit the animals on your own.
Docent-guided -- offering a richer zoo experience where the docent provides added value, leading visitors around the zoo, answering questions, providing education, and comparing the differences between the animals.
Over the past 15 years, IBM has been consolidating storage development in Tucson, Arizona moving storage-related projects from San Jose, CA, from Rochester, MN, and from Raleigh, NC. Tucson has the largest collection of IBM storage hardware and software development in North America. I am one of the three local "docents", guiding the clients that come to Tucson to visit the developers.
Here are some of the types of developers that our clients ask to interact with:
A was hired into IBM back in 1986 as a Research Scientist. When clients want to hear about IBM's future direction over the next 10-15 years, we bring in someone from IBM Research.
While disk systems may seem no more complicated as arranging books on a shelf, clients often want to talk to hardware engineers related to IBM's tape libraries, especially the IBM System Storage TS3500 library and the High-Density frame that can store multiple cartridges per slot in a spring-loaded manner.
I have a Bachelor's degree in Computer Engineering and Master's degree in Electrical Engineering, so I am able to speak both sides of the hardware/software divide. Software engineers here in Tucson develop the microcode that runs on disk and tape hardware, the various GUI, CLI and SMI-S API interfaces, as well as Tivoli Storage software, especially Tivoli Storage Manager (TSM) and Tivoli Storage Productivity Center.
IBM Tucson has a huge test lab, and our testers are very familiar with all of the subtle nuances of interoperability between servers, HBAs, switches and storage devices. We have system and function testers for the individual products, ISV testers to validate software compatability, performance testers, and environment testers to verify the storage devices can handle extremes in temperature, humidity, vibration and noise.
IBM has architects for each product line to help decide which features and functions are developed for each product release. While many software engineers have expertise narrowly focused on an individual component, the system architects need to have a broad awareness of the entire environment. Earlier in my career, I was the chief architect for DFSMS, the storage management element of the z/OS mainframe operating sytsem, and chief architect for what we now call Tivoli Storage Productivity Center.
Product and Portfolio Managers
Product and Portfolio managers are helpful to explain to clients why IBM invested more in some products than others. I had served as the Portfolio Manager for IBM tape systems. When clients want to talk about the business side of our products, such as pricing, licensing and leasing issues, we bring the product and portfolio managers in.
For some clients, high level executives want to speak to their counterparts at IBM, vice president to vice president, executive to executive. Our local IBM executives often help kick off the briefing in the morning, or provide the executive summary and discuss next steps at the end of the day. Golfing, dinners and drinks, of course, are always a popular scheduing option.
On behalf of the rest of the Tucson EBC, I would like to thank all the developers who have helped us last year with client briefings. There are too many to mention, and most are too humble to let me put their names in this blog. Team, your assistance is very appreciated!
Many IBMers consider Tucson to be the headquarters for storage, and I have heard IBM executives refer to Tucson as the center of the universe for storage products. However, IBM is a global company. Just as zoos do not pretend to be complete collections of animals, IBM storage development is not entirely contained in Tucson. IBM Research for storage is also done in Almaden CA, Yorktown Heights NY, and Haifa, Israel. Hardware development is also done in Japan, Europe and Israel. Tivoli Storage has locations in Beaverton, Oregon, and Austin, Texas, to name a few. IBM is a big company, so if I left your favorite location off the list, let me know in the comments below.
Some clients, sales reps and business partners have complained that Tucson is not the most convenient location to get to. I get that. One rep asked why we don't have briefing centers somewhere more accessible, such as Chicago or Atlanta, both cities offer a major airline hub. As much as I personally enjoy cities like Chicago or Atlanta, people don't visit zoos just to see the docents, they come to see the animals. Having docents located in Chicago or Atlanta, standing sadly in front of empty cages with no animals to interact with, makes no sense at all.
With over 350 days of sunshine per year, Tucson is actually a well-kept secret. Clients who have never been to Tucson discover the wonders of the Sonoran desert. Coyotes chase roadrunners across our parking lot. Several clients who have come to visit us have ended up buying retirement homes here. If you haven't been to Tucson, or it has been a while since your last trip, I encourage you to [schedule a briefing]. The weather right now is ideal!
Did IBM XIV force EMC's hand to announce VMAXe? Let's take a stroll down memory lane.
In 2008, IBM XIV showed the world that it could ship a Tier-1, high-end, enterprise-class system using commodity parts. Technically, prior to its acquisition by IBM, the XIV team had boxes out in production since 2005. EMC incorrectly argued this announcement meant the death of the IBM DS8000. Just because EMC was unable to figure out how to have more than one high-end disk product, doesn't mean IBM or other storage vendors were equally challenged. Both IBM XIV and DS8000 are Tier-1, high-end, enterprise-class storage systems, as are the IBM N series N7900 and the IBM Scale-Out Network Attached Storage (SONAS).
In April 2009, EMC followed IBM's lead with their own V-Max system, based on Symmetrix Engenuity code, but on commodity x86 processors. Nobody at EMC suggested that the V-Max meant the death of their other Symmetrix box, the DMX-4, which means that EMC proved to themselves that a storage vendor could offer multiple high-end disk systems. Hitachi Data Systems (HDS) would later offer the VSP, which also includes some commodity hardware as well.
In July 2009, analysts at International Technology Group published their TCO findings that IBM XIV was 63 percent less expensive than EMC V-Max, in a whitepaper titled [COST/BENEFIT CASE
FOR IBM XIV STORAGE SYSTEM Comparing Costs for IBM XIV and EMC V-Max Systems]. Not surprisingly, EMC cried foul, feeling that EMC V-Max had not yet been successful in the field, it was too soon to compare newly minted EMC gear with a mature product like XIV that had been in production accounts for several years. Big companies like to wait for "Generation 1" of any new product to mature a bit before they purchase.
To compete against IBM XIV's very low TCO, EMC was forced to either deeply discount their Symmetrix, or counter-offer with lower-cost CLARiiON, their midrange disk offering. An ex-EMCer that now works for IBM on the XIV sales team put it in EMC terms -- "the IBM XIV provides a Symmetrix-like product at CLARiiON-like prices."
(Note: Somewhere in 2010, EMC dropped the hyphen, changing the name from V-Max to VMAX. I didn't see this formally announced anywhere, but it seems that the new spelling is the officially correct usage. A common marketing rule is that you should only rename failed products, so perhaps dropping the hyphen was EMC's way of preventing people from searching older reviews of the V-Max product.)
This month, IBM introduced the IBM XIV Gen3 model 114. The analysts at ITG updated their analysis, as there are now more customers that have either or both products, to provide a more thorough comparison. Their latest whitepaper, titled [Cost/Benefit Case for IBM XIV Systems: Comparing Cost
Structures for IBM XIV and EMC VMAX Systems], shows that IBM maintains its substantial cost savings advantage, representing 69 percent less Total Cost of Ownership (TCO) than EMC, on average, over the course of three years.
In response, EMC announced its new VMAXe, following the naming convention EMC established for VNX and VNXe. Customers cannot upgrade VNXe to VNX, nor VMAXe to VMAX, so at least EMC was consistent in that regard. Like the IBM XIV and XIV Gen3, the new EMC VMAXe eliminated "unnecessary distractions" like CKD volumes and FICON attachment needed for the IBM z/OS operating system on IBM System z mainframes. Fellow blogger Barry Burke from EMC explains everything about the VMAXe in his blog post [a big thing in a small package].
So, you have to wonder, did IBM XIV force EMC's hand into offering this new VMAXe storage unit? Surely, EMC sales reps will continue to lead with the more profitable DMX-4 or VMAX, and then only offer the VMAXe when the prospective customer mentions that the IBM XIV Gen3 is 69 percent less expensive. I haven't seen any list or street prices for the VMAXe yet, but I suspect it is less expensive than VMAX, on a dollar-per-GB basis, so that EMC will not have to discount it as much to compete against IBM.
In his last post in this series, he mentions that the amazingly successful IBM SAN Volume Controller was part of a set of projects:
"IBM was looking for "new horizon" projects to fund at the time, and three such projects were proposed and created the "Storage Software Group". Those three projects became know externally as TPC, (TotalStorage Productivity Center), SanFS (SAN File System - oh how this was just 5 years too early) and SVC (SAN Volume Controller). The fact that two out of the three of them still exist today is actually pretty good. All of these products came out of research, and its a sad state of affairs when research teams are measured against the percentage of the projects they work on, versus those that turn into revenue generating streams."
But this raises the question: Was SAN File System just five years too early?
IBM classifies products into three "horizons"; Horizon-1 for well-established mature products, Horizon-2 was for recently launched products, and Horizon-3 was for emerging business opportunities (EBO). Since I had some involvement with these other projects, I thought I would help fill out some of this history from my perspective.
Back in 2000, IBM executive [Linda Sanford] was in charge of IBM storage business and presented that IBM Research was working on the concept of "Storage Tank" which would hold Petabytes of data accessible to mainframes and distributed servers.
In 2001, I was the lead architect of DFSMS for the IBM z/OS operating system for mainframes, and was asked to be lead architect for the new "Horizon 3" project to be called IBM TotalStorage Productivity Center (TPC), which has since been renamed to IBM Tivoli Storage Productivity Center.
In 2002, I was asked to lead a team to port the "SANfs client" for SAN File System from Linux-x86 over to Linux on System z. How easy or difficult to port any code depends on how well it was written with the intent to be ported, and porting the "proof-of-concept" level code proved a bit too challenging for my team of relative new-hires. Once code written by research scientists is sufficiently complete to demonstrate proof of concept, it should be entirely discarded and written from scratch by professional software engineers that follow proper development and documentation procedures. We reminded management of this, and they decided not to make the necessary investment to add Linux on System z as a supported operating system for SAN file system.
In 2003, IBM launched Productivity Center, SAN File System and SAN Volume Controller. These would be lumped together with Horizon-1 product IBM Tivoli Storage Manager and the four products were promoted together as the inappropriately-named [TotalStorage Open Software Family]. We actually had long meetings debating whether SAN Volume Controller was hardware or software. While it is true that most of the features and functions of SAN Volume Controller is driven by its software, it was never packaged as a software-only offering.
The SAN File System was the productized version of the "Storage Tank" research project. While the SAN Volume Controller used industry standard Fibre Channel Protocol (FCP) to allow support of a variety of operating system clients, the SAN File System required an installed "client" that was only available initially on AIX and Linux-x86. In keeping with the "open" concept, an "open source reference client" was made available so that the folks at Hewlett-Packard, Sun Microsystems and Microsoft could port this over to their respective HP-UX, Solaris and Windows operating systems. Not surprisingly, none were willing to voluntarily add yet another file system to their testing efforts.
Barry argues that SANfs was five years ahead of its time. SAN File System tried to bring policy-based management for information, which has been part of DFSMS for z/OS since the 1980s, over to distributed operating systems. The problem is that mainframe people who understand and appreciate the benefits of policy-based management already had it, and non-mainframe couldn't understand the benefits of something they have managed to survive without.
(Every time I see VMware presented as a new or clever idea, I have to remind people that this x86-based hypervisor basically implements the mainframe concept of server virtualization introduced by IBM in the 1970s. IBM is the leading reseller of VMware, and supports other server virtualization solutions including Linux KVM, Xen, Hyper-V and PowerVM.)
To address the various concerns about SAN File System, the proof-of-concept code from IBM Research was withdrawn from marketing, and new fresh code implementing these concepts were integrated into IBM's existing General Parallel File System (GPFS). This software would then be packaged with a server hardware cluster, exporting global file spaces with broad operating system reach. Initially offered as IBM Scale-out File Services (SoFS) service offering, this was later re-packaged as an appliance, the IBM Scale-Out Network Attached Storage (SONAS) product, and as IBM Smart Business Storage Cloud (SBSC) cloud storage offering. These now offer clustered NAS storage using the industry standard NFS and CIFS clients that nearly all operating systems already have.
Today, these former Horizon-1 products are now Horizon-2 and Horizon-3. They have evolved. Tivoli Storage Productivity Center, GPFS and SAN Volume Controller are all market leaders in their respective areas.
“In times of universal deceit, telling the truth will be a revolutionary act.”
-- George Orwell
Well, it has been over two years since I first covered IBM's acquisition of the XIV company. Amazingly, I still see a lot of misperceptions out in the blogosphere, especially those regarding double drive failures for the XIV storage system. Despite various attempts to [explain XIV resiliency] and to [dispel the rumors], there are still competitors making stuff up, putting fear, uncertainty and doubt into the minds of prospective XIV clients.
Clients love the IBM XIV storage system! In this economy, companies are not stupid. Before buying any enterprise-class disk system, they ask the tough questions, run evaluation tests, and all the other due diligence often referred to as "kicking the tires". Here is what some IBM clients have said about their XIV systems:
“3-5 minutes vs. 8-10 hours rebuild time...”
-- satisfied XIV client
“...we tested an entire module failure - all data is re-distributed in under 6 hours...only 3-5% performance degradation during rebuild...”
-- excited XIV client
“Not only did XIV meet our expectations, it greatly exceeded them...”
In this blog post, I hope to set the record straight. It is not my intent to embarrass anyone in particular, so instead will focus on a fact-based approach.
Fact: IBM has sold THOUSANDS of XIV systems
XIV is "proven" technology with thousands of XIV systems in company data centers. And by systems, I mean full disk systems with 6 to 15 modules in a single rack, twelve drives per module. That equates to hundreds of thousands of disk drives in production TODAY, comparable to the number of disk drives studied by [Google], and [Carnegie Mellon University] that I discussed in my blog post [Fleet Cars and Skin Cells].
Fact: To date, no customer has lost data as a result of a Double Drive Failure on XIV storage system
This has always been true, both when XIV was a stand-alone company and since the IBM acquisition two years ago. When examining the resilience of an array to any single or multiple component failures, it's important to understand the architecture and the design of the system and not assume all systems are alike. At it's core, XIV is a grid-based storage system. IBM XIV does not use traditional RAID-5 or RAID-10 method, but instead data is distributed across loosely connected data modules which act as independent building blocks. XIV divides each LUN into 1MB "chunks", and stores two copies of each chunk on separate drives in separate modules. We call this "RAID-X".
Spreading all the data across many drives is not unique to XIV. Many disk systems, including EMC CLARiiON-based V-Max, HP EVA, and Hitachi Data Systems (HDS) USP-V, allow customers to get XIV-like performance by spreading LUNs across multiple RAID ranks. This is known in the industry as "wide-striping". Some vendors use the terms "metavolumes" or "extent pools" to refer to their implementations of wide-striping. Clients have coined their own phrases, such as "stripes across stripes", "plaid stripes", or "RAID 500". It is highly unlikely that an XIV will experience a double drive failure that ultimately requires recovery of files or LUNs, and is substantially less vulnerable to data loss than an EVA, USP-V or V-Max configured in RAID-5. Fellow blogger Keith Stevenson (IBM) compared XIV's RAID-X design to other forms of RAID in his post [RAID in the 21st Centure].
Fact: IBM XIV is designed to minimize the likelihood and impact of a double drive failure
The independent failure of two drives is a rare occurrence. More data has been lost from hash collisions on EMC Centera than from double drive failures on XIV, and hash collisions are also very rare. While the published worst-case time to re-protect from a 1TB drive failure for a fully-configured XIV is 30 minutes, field experience shows XIV regaining full redundancy on average in 12 minutes. That is 40 times less likely than a typical 8-10 hour window for a RAID-5 configuration.
A lot of bad things can happen in those 8-10 hours of traditional RAID rebuild. Performance can be seriously degraded. Other components may be affected, as they share cache, connected to the same backplane or bus, or co-dependent in some other manner. An engineer supporting the customer onsite during a RAID-5 rebuild might pull the wrong drive, thereby causing a double drive failure they were hoping to avoid. Having IBM XIV rebuild in only a few minutes addresses this "human factor".
In his post [XIV drive management], fellow blogger Jim Kelly (IBM) covers a variety of reasons why storage admins feel double drive failures are more than just random chance. XIV avoids load stress normally associated with traditional RAID rebuild by evenly spreading out the workload across all drives. This is known in the industry as "wear-leveling". When the first drive fails, the recovery is spread across the remaining 179 drives, so that each drive only processes about 1 percent of the data. The [Ultrastar A7K1000] 1TB SATA disk drives that IBM uses from HGST have specified 1.2 million hours mean-time-between-failures [MTBF] would average about one drive failing every nine months in a 180-drive XIV system. However, field experience shows that an XIV system will experience, on average, one drive failure per 13 months, comparable to what companies experience with more robust Fibre Channel drives. That's innovative XIV wear-leveling at work!
Fact: In the highly unlikely event that a DDF were to occur, you will have full read/write access to nearly all of your data on the XIV, all but a few GB.
Even though it has NEVER happened in the field, some clients and prospects are curious what a double drive failure on an XIV would look like. First, a critical alert message would be sent to both the client and IBM, and a "union list" is generated, identifying all the chunks in common. The worst case on a 15-module XIV fully loaded with 79TB data is approximately 9000 chunks, or 9GB of data. The remaining 78.991 TB of unaffected data are fully accessible for read or write. Any I/O requests for the chunks in the "union list" will have no response yet, so there is no way for host applications to access outdated information or cause any corruption.
(One blogger compared losing data on the XIV to drilling a hole through the phone book. Mathematically, the drill bit would be only 1/16th of an inch, or 1.60 millimeters for you folks outside the USA. Enough to knock out perhaps one character from a name or phone number on each page. If you have ever seen an actor in the movies look up a phone number in a telephone booth then yank out a page from the phone book, the XIV equivalent would be cutting out 1/8th of a page from an 1100 page phone book. In both cases, all of the rest of the unaffected information is full accessible, and it is easy to identify which information is missing.)
If the second drive failed several minutes after the first drive, the process for full redundancy is already well under way. This means the union list is considerably shorter or completely empty, and substantially fewer chunks are impacted. Contrast this with RAID-5, where being 99 percent complete on the rebuild when the second drive fails is just as catastrophic as having both drives fail simultaneously.
Fact: After a DDF event, the files on these few GB can be identified for recovery.
Once IBM receives notification of a critical event, an IBM engineer immediately connects to the XIV using remote service support method. There is no need to send someone physically onsite, the repair actions can be done remotely. The IBM engineer has tools from HGST to recover, in most cases, all of the data.
Any "union" chunk that the HGST tools are unable to recover will be set to "media error" mode. The IBM engineer can provide the client a list of the XIV LUNs and LBAs that are on the "media error" list. From this list, the client can determine which hosts these LUNs are attached to, and run file scan utility to the file systems that these LUNs represent. Files that get a media error during this scan will be listed as needing recovery. A chunk could contain several small files, or the chunk could be just part of a large file. To minimize time, the scans and recoveries can all be prioritized and performed in parallel across host systems zoned to these LUNs.
As with any file or volume recovery, keep in mind that these might be part of a larger consistency group, and that your recovery procedures should make sense for the applications involved. In any case, you are probably going to be up-and-running in less time with XIV than recovery from a RAID-5 double failure would take, and certainly nowhere near "beyond repair" that other vendors might have you believe.
Fact: This does not mean you can eliminate all Disaster Recovery planning!
To put this in perspective, you are more likely to lose XIV data from an earthquake, hurricane, fire or flood than from a double drive failure. As with any unlikely disaster, it is best to have a disaster recovery plan than to hope it never happens. All disk systems that sit on a single datacenter floor are vulnerable to such disasters.
For mission-critical applications, IBM recommends using disk mirroring capability. IBM XIV storage system offers synchronous and asynchronous mirroring natively, both included at no additional charge.
Well, I am back safely from my trip last week to Chicago, and now I am writing this in Madrid, Spain, on my way to Brussels, Belgium for the IT Storage Expo.
For those who have asked how the construction on the new Tucson EBC is going, here are a few pictures I took on Friday. As you can see, it is coming along nicely. The official grand opening will be April 2.
Here are some upcoming events related to IBM Storage!
If you sell IBM and/or Oracle solutions, please join me for IBM Oracle Virtual University 2013!
A few weeks ago, I recorded a session on IBM Storage: Overview, Positioning and How to Sell that will be available on demand starting tomorrow, February 26th, at the IBM Oracle Virtual University 2013.
It's one of 65 new sessions that will help IBM to surround Oracle applications with IBM infrastructure, services and industry solutions. Oracle software, after all, runs best on IBM hardware. Other highlights of Oracle Virtual University include a live executive State of the Alliance session with Q&A, Oracle keynote, updates by Oracle product managers, sessions on PureSystems, Selling IBM into an Oracle environment, Cloud, and much more.
There will be live technical teams on hand throughout launch day to answer your questions in real time, so I hope you can carve out 30 minutes or more on February 26th to take advantage of these available resources.
After helping launch the first Pulse back in 2008, I have sadly not been back since. Last year, I was invited to attend as a last-minute replacement for another speaker, but I was busy [having emergency surgery].
This year's [Pulse 2013] conference looks amazing. It will be held in Las Vegas, Nevada. Guest Speaker Payton Manning, NFL 4-time MVP football player, and Carrie Underwood, 6-time Grammy award winner, join IBM's Software Group executives and experts on how IBM Tivoli can help optimize your IT infrastructure.
Sadly, once again, I will not be there at Pulse. This time, I will be on the East Coast visiting clients instead, but my on-premise correspondent, Tom Rauchut, has informed me that he will be there. Hopefully, he will provide me something to write about.
Later in March, I will be in Brussels, Belgium for the Storage Expo. This is held March 20-21, at the Brussels-Expo venue. I will be presenting several topics each day, as well as visit clients in the area. This event comes on behalf of IBM Belgium in association with IBM Business Partner IRIS-ICT.
If you plan to participate in any of these events, let me know!
Recently, I spoke with Jarrett Potts, my long-time friend and former IBM colleague, who now works as Director of Strategic Marketing over at STORServer. If you have never heard of STORServer, it is a company that makes purpose-built backup appliances.
What is a Backup Appliance? It is an integrated solution of hardware and software that serves a single purpose: backup and recovery. STORServer Enterprise Backup Appliance (EBA) combines IBM's high-end x86 M4 server, IBM disk and tape storage, and IBM Tivoli Storage Manager (TSM) backup software.
(Fun Fact: The 2012 IBM year-end financial results were announced last month. IBM not only continues its #1 lead in servers overall, but has the #1 marketshare for high-end x86 servers, market-leading disk and tape storage hardware, and market leading backup software.)
To determine the appropriate size of your backup appliance, the folks at STORServer help you every step of the way. They figure out the number of TB you will backup every day, and even help configure all of the TSM server parameters to achieve the policies that make the most sense for your organization.
The appliance can backup every type of data, from databases and Virtual Machines (VMs) to documents, spreadsheets, and other unstructured data.
Are you then left with a solution too complicated to run yourself? No. The STORServer Console is an easy-to-use GUI for ongoing monitoring and maintenance. Plus, your friends at STORServer are only a phone call away in case you have any questions.
(FTC Disclosure: I work for IBM, and STORSever is an approved IBM Business Partner that uses IBM hardware and software to build their solution. I have no financial interest in STORServer, and was not paid by STORServer to mention their company or products on my blog. This post may be considered a celebrity endorsement of STORServer and its Enterprise Backup Appliances.)
Perhaps my readers feel that I am a bit biased in describing a TSM-based solution, and you want a second opinion. No worries, I understand. In the latest 165-page [2012 DCIG Backup Appliance Buyer's Guide], the STORServer models ranked very high. Here is an excerpt:
"Nowhere is this demand for purpose built appliances more evident than in the rise of purpose
built backup appliances (PBBAs) over the last few years and their anticipated growth rate
going forward. A recent market analysis performed by IDC found that worldwide PBBA revenue totaled $2.4 billion in 2011 which was a 42.4 percent increase over the prior year.
This scoring came into play in preparing this Buyer's Guide
as the STORServer EBA 3100 model scored so highly
overall that it fell outside of the two (2) standard deviations
that DCIG generally uses as a guideline for inclusion and
exclusion of products.
The reason DCIG included this model in this Buyer's Guide
whereas in other situations it might not is that DCIG is
unaware of any other backup appliance(s) from any other
providers that come close to matching the EBA 3100's
software and hardware attributes. As such, DCIG felt it
would be doing STORServer specifically and the market
generally a disservice by not highlighting in this Buyer's
Guide that such a backup appliance existed and was
generally available for purchase."
Backup Appliance Models
STORServer EBA 3100
Symantec NetBackup 5220 Backup Appliance
STORServer EBA 2100
STORServer EBA 1100
STORServer EBA 800
Symantec Backup Exec 3600 Appliance
The STORServer is ideal for small and medium-sized business (SMB), but can scale quite large to handle business growth. If you are currently unhappy with your current backup environment, and feel now is the time to look around for a better way of taking backups, you won't go wrong choosing a solution based on IBM's market-leading server and storage hardware with Tivoli Storage Manager software.
I've gotten suggestions to upgrade the memory and disk storage, and how to fine-tune the Microsoft Windows XP operating system. Others suggested replacing the OS with Linux, and to use the Cloud to avoid some of the storage space limitations.
But first, I have to mention the latest in our series of "Enterprise Systems" videos. The first was being [Data Ready]. The second was being [Security Ready]. The now the third in the series: the 3-minute
[Cloud Ready] video.
So I decided to try different Cloud-oriented Operating Systems, to see if any would be a good fit. Here is what I found:
(FTC Disclosure: I work for IBM and own IBM stock. This blog post is not meant to endorse one OS over another. I have financial interests in, and/or have friends and family who work at some of the various companies mentioned in this post. Some of these companies also have business relationships with IBM.)
Jolicloud and Joli OS 1.2
I gave this OS a try. This is based on Linux, but with an interesting approach. First, you have to be on-line all the time, and this OS is designed for 15-25 year-olds who are on social media websites like Facebook. By having a Jolicloud account, you can access this from any browser on any system, or run the Joli OS operating system, or buy the already pre-installed Jolibook netbook computer.
The Joli OS 1.2 LiveCD ran fine on my T410 with 4GB or RAM, giving me a chance to check it out, but sadly did not run on grandma's Thinkpad R31 with 384MB of RAM. According to the [Jolicloud specifications], Joli OS should run in as little as 384MB of RAM and 2GB of disk storage space, but it didn't for me.
Google Chrome and Chromium OS Vanilla
Like the Jolibook, Google has come out with a $249 Chromebook laptop that runs their "Chrome OS". This is only available via OEM install on desginated hardware, but the open source version is available called Chromium OS. These are also based on Linux.
Rather than compiling from source, Hexxeh has made nightly builds available. You can download [Chromium OS Vanilla] zip file, unzip the image file, and copy it to a 4GB USB memory stick. The compressed image is about 300MB, but uncompressed about 2.5GB, so too big to fit on a CD. The image on the USB stick is actually two partitions, and cannot be run from DVD either.
If you don't have a 4GB USB stick handy, and want to see what all the fuss is about, just install the Google Chrome browser on your Windows or Linux system, and then maximize the browser window. That's it. That is basically what Chromium OS is all about.
Files can be stored locally, or out on your Google Drive. Documents can be edited using "Google Docs" in the Cloud. You can run in "off-line" mode, for example, read your Gmail notes when not connected to the Internet. Music and video files can be played using the "Files" app.
If you really need to get out of the browser, you can hit the right combination of keys to get to the "crosh" command line shell.
Like Joli OS, I was able to run this from my Thinkpad T410 with 4GB of RAM, but not on grandma's Thinkpad R31. It appears that Chromium requires at least 1GB of RAM to run properly.
Android for x86
While researching the Chromium OS, I found that there is an open source community porting [Android to the x86] platform. Android is based on Linux, and would allow your laptop or netbook to run very much like a smartphone or tablet. Most of the apps available to Android should work here as well.
Unfortunately, the project has focused only on selected hardware:
ASUS Eee PCs/Laptops
Viewsonic Viewpad 10
Dell Inspiron Mini Duo
Lenovo ThinkPad x61 Tablet
I tried running the Thinkpad x61 version on both my Thinkpad T410 and grandma's Thinkpad R31, but with no success.
Peppermint OS Three
Next up was Peppermint OS, which claims to be a blend of Linux Mint, Lubuntu, and Xfce, but with a "twist" of aspiring to be a Cloud-oriented OS.
Rather than traditional apps to write documents or maintain a calendar, this OS offers a "Single-Site Browser" (SSB) experience, where you can configure "apps" by pointing to their respective URL. For documents, launch GWoffice, the client for Google Docs. For calendar, launch Google Calendar.
Most Linux distros have both a number and a project name associated with them. For example, Ubuntu 10.04 LTS is known as "Lucid Lynx". The Peppermint OS team avoided this by just calling their latest version "Three" which serves as both its number and its name.
The browser is Chromium, similar to Google Chrome OS above, and uses the "DuckDuckGo" search engine. This is how the Peppermint OS folks make their money to defray the costs of this effort.
Peppermint OS claims to run in systems as little as 192MB or RAM, and only 4GB of disk space. The LiveCD ran well on both my Thinkpad T410, as well as grandma's Thinkpad R31. More importantly, when I installed on the hard drive, it ran well.
The music app "Guayadeque" that came pre-installed was awful. It couldn't play MP3 music out-of-the-box. I had to install the Codec plugins from various "ubuntu-restricted-extras" libraries. I also installed the music app "Rhythmbox", and that worked great. Time from power-on to first-note was less than 2 minutes! However, the problems with the Guayadeque gave me the impression this OS might not be ready for primetime.
I contacted grandma to ask if she has Wi-Fi in her home, and sure enough, she doesn't. Her PC upstairs is direct attached to the cable modem. So, while the Cloud suggestion was worthy of investigation, I will continue to pursue other options that do not require being connected. I certainly do not want to spend any time and effort getting Wi-Fi installed there.
Well it's Wednesday, and you know what that means... IBM Announcements.
(Normally, announcements are on Tuesdays, but we moved this one over to Wednesday to line up with our big launch event in Pinehurst, NC. )
A lot was announced today, so I decided to break it up into several separate posts. I will start with our Enterprise Systems: DS8870, TS7700 Release 3, and XIV Gen3.
Enterprise systems are the servers, storage and software at the core of an enterprise IT infrastructure. Enterprise systems enable a private cloud infrastructure at enterprise scale, with flexible service delivery models that provide dynamic efficiency for resource and workload management. They make sure critical data is always available across the enterprise, making it accessible in new ways so that actionable insights can be derived from advanced and operational analytics. They also provide ultimate security, ensuring the integrity of critical data while mitigating risk and providing assured compliance.
IBM System Storage DS8870® disk system
This new storage system is the next generation in IBM's DS8000 series, based on IBM's POWER7 chipset. Each CEC can have 2, 4, 8 or 16 cores. Like the DS8800, you can have a mix of 2.5-inch and 3.5-inch disk drives of different speeds and capacities, up to 1,536 drives in a four-frame configuration. The maximum cache is now 1TB usable. The combination of faster chipset and more cache can triple performance for some workloads!
All DS8870s ship standard with all Full Disk Encryption (FDE-capable) drives. The problem in the past was that people would buy DS8000 with non-FDE drives, and then later want to activate encryption, and discovered that they have to swap out their drives with those with the encryption chip built in. Now, all drives on the DS8870 will have the encryption chip. This also allows Easy Tier sub-volume automated tiering to move encrypted data between all media types.
Flash optimization with DS8000 Easy Tier can improve performance up to 3 times with 3% of data on solid-state storage. Easy Tier is easy to deploy and runs automatically.
Support of the American National Standards Institute's (ANSI) T10 Data Integrity Field (DIF) standard. This is a feature that the mainframe has had for years, and is now being extended to distributed operating systems. The concept is simple. When sending data between server and storage, generate a checksum at the source, and then validate the checksum at the target. When you write a block of data, the server generates the checksum, and the DS8870 validates the checksum on arrival. When you read the data back, the DS8870 generates the checksum, and the server validates it on arrival. This ensures that data was not corrupted in between. There is a great write-up on IBM developerWorks: [End-to-end data protection using T10 standard data integrity field].
Energy Efficient. The DS8870 consumes less energy than its predecessor, the DS8800. For example, a fully-configured four-frame DS8870 with 1,536 disk drives consumes only 23.2kW, compared to the same number of drives in a DS8800 consumed 26.3 kW. By comparison, the DS8700 with five frames and 1,024 drives consumed 29.2kW.
Support for new System z load balancing algorithm. System z Workload Manager now interacts with the DS8870 I/O Priority Manager to optimize designated Quality of Service (QoS) levels. We have also the fastest operational analytics solution with DB2 list Prefetch cache optimization with DS8870 High Performance FICON (zHPF) integration. This solution increases DB2 query performance up to 11 times with disk, and up to 60 times with solid-state drives (SSD). File scans are up to 30 percent faster using DS8870 zHPF support for sequential access methods (QSAM, BPAM, and BSAM).
VMware vStorage APIs for Array Integration (VAAI) support. Why should the IBM DS8800 series support VMware when IBM already offers great VMware support with SAN Volume Controller (SVC), Storwize V7000 and XIV storage sytsems? Good question. This was hotly debated between development and marketing. Several DS8000 customers have already added SVC to provide full VMware VAAI support. As a consultant, I am neither development nor marketing, but felt it necessary to weigh in on my opinion on this. The DS8000 is a consolidation platform. According to one analyst survey, 22 percent of companies run on a single disk platform, so for DS8000 to be the one, it needs to support VMware and exploit these special APIs.
Six Nines Availability. Critical enterprise systems need to deliver continuous data availability, or very close to it. IBM solutions can help deliver up to six “nines” of availability, or 99.9999 percent when combining DS8000 Metro Mirror and GDPS Hyperswap. That's less than 30 seconds of downtime per year.
The TS7700 Release 3 represents a refresh to our existing virtual tape libraries. These are mainframe-only, offered in two models: TS7720 is a disk-only device, and the TS7740 is a blended disk-and-tape solution.
Industry standard hardware encryption. This applies to user data stored on the TS7700 system cache (disk), and for data transferred between TS7700 systems. This is especially important for regulations, like Payment Card Industry Data Security Standard (PCI-DSS). In previous models, the data would not be encrypted until it was moved off disk and written to tape. Now, it is encrypted the minute in lands on the disk cache, and stays encrypted as it is replicated from one TS7700 to another in the grid.
Up to 4 Million logical volume capacity. This is twice the previous support.
More physical capacity for TS7720 systems. The maximum capacity for the disk-only model is raised from 440TB to 620TB, representing a 40 percent increase.
My latest book "Inside System Storage: Volume V" is now available!
I have published my fifth volume in my "Inside System Storage" series! Currently, it is only available in Paperback. My editor, Susan Pollard, is hoping to have the eBook and Hardcover versions ready for Cyber Monday. The foreword was written by my Dr. Sondra Ashmore.
You can order this, and all my other books, in all formats, directly from my [Author Spotlight] page. The paperback will also be available soon from other online booksellers, search for ISBN 978-1-300-26223-7.
Improved Scalability. A new Multi-system Manager (MSM) server reduces the operational complexity for large and multi-site XIV deployments. Previously, admins connected directly to XIV boxes. If you had 10 admins logged in, then every XIV box was managing 10 admin conversations. The new MSM acts as a go-between. The admins connect to the MSM, and the MSM connects to the XIV boxes. The MSM polls and caches the status of each XIV, greatly increasing the number of XIV boxes that an admin can manage.
Enhanced User Interface. A new Multi-system Manager server reduces the operational complexity for large and multi-site XIV deployments. We also added support for IPsec and US. Government (USGv6) certification for admistering the XIV over IPv6 networks. The XIV Mobile Dashboard app for iPhone and iPad is spiffed up. Finally, the GUI has been internationalized and translated to the Japanese language.
Enhanced Integration for Cloud. For OpenStack, XIV now offers a Nova-volume driver which provides persistent storage to OpenStack compute nodes. The Nova task force is now looking to move storage into its own project called Cinder. For VMware, XIV has full support for Site Recovery Manager (SRM) v4.1 and v5.0 releases. XIV now also supports the Microsoft System Center Virtual Machine Manager, which can manage Hyper-V, VMware and Citrix XenServer hypervisors.
Smaller entry point. The original XIV supported 1TB and 2TB drives, with the smallest offering being 27TB usable. When IBM introduced the XIV Gen3, the two choices were 2TB and 3TB disk drives. Unfortunately, this meant that the initial entry model was now 55TB in size, and each additional module would be more expensive as well. IBM is now going to offer 1TB support for XIV Gen3 for a lower price point, these are actually 2TB drives with half the capacity turned off.
Well it's Tuesday again, and you know what that means... IBM announcements! Yesterday, at the IBM Edge conference here in Orlando, Florida, IBM announced its new apporach to storage, and a whole bunch of storage products, enhancements, and services. I will focus on some key ones here, and save the rest for next week.
IBM SAN Volume Controller (SVC) v6.4
The SVC is IBM's enterprise-class storage hypervisor. The latest software release, v6.4, can be installed on any SVC hardware, from the 2145-8F2 introduced back in 2005, to newer models like the 2145-CG8. Here are the key features:
Fibre Channel over Ethernet (FCoE) -- This is complete end-to-end support. For SVC units with 10GbE ports, these ports can be now be used for FCoE. This allows hosts to attach to SVC via FCoE, allows SVC node-to-node communication for clustering, and allows SVC to communicate to back-end devices via FCoE.
Real-Time Compression -- IBM ported over the patent Random Access Compression Engine (RACE) from the Real-Time Compression Appliances to SVC v6.4. This allows primary data, accessed via block-based protocols, to be compressed up to 80 percent. This feature is an extra priced feature by TB.
Non-Disruptive Volume move between I/O Groups -- If you don't already have SVC, you don't need to worry about this. For existing SVC customers, this allows volumes to be associated with two or more I/O groups, and that you can add or remove I/O groups non-disruptively. For example, if you want to move a volume from IOG1 to IOG2, then you add IOG2 to the list of I/O groups for the volume, let the multi-pathing software discover the additional paths, the remove IOG1, which then marks the previous IOG1 paths inactive. All this can be done while applications read and write data.
Dedicate FCP ports for Replication -- If you activate the two 10GbE Ethernet ports for FCoE, you can free up two FCP ports that you can dedicate for long-distance Metro Mirror or Global Mirror.
If you have SVC today, but are running an old release like v4.3 or v5.1, I recommennd you upgrade up to at least v6.2.05 release now. This release has been out for a year and is very stable, and serves as a great platform for a later upgrade to SVC v6.4.
IBM Storwize V7000 v6.4
The Storwize V7000 is IBM's midrange storage hypervisor. The latest software release, v6.4, can be installed on existing block-only Storwize V7000 units in the field. The Storwize V7000 v6.4 gets all the features listed above, as well as the following:
Four-way clustering -- Previously, you could cluster two Storwize V7000 controller enclosures together (4 canisters total). To cluster three or four controllers required an RPQ. Now, IBM supports up to four Storwize V7000 controller enclosures (8 canisters) without an RPQ.
Direct Fibre Channel attach -- A lot of people are using Storwize V7000 inside single-rack configurations, so it makes sense not to require a SAN switch for just a few Windows, Linux or VMware servers. An RPQ is now available to allow this to happen.
IBM Tivoli Storage Productivity Center (TPC) v5.1
TPC is already ranked one of the best Storage Infrastructure Management software in the market, and this release will just solidify its lead. Key features include:
Upward integration to higher level management systems
A new, intuitive, easy-to-use web-based GUI inspired by the XIV GUI
Integration of COGNOS to be able to generate and customize reports
Support for SONAS systems
There are several presentations on TPC this week that will go into more detail. Check out the [TPC Facebook page].
My latest book Inside System Storage: Volume IV is now available!
Yes, can you believe it? I have published my fourth volume in my "Inside System Storage" series! It is available in three formats:
Hardcover with dust jacket
eBook (Adobe Acrobat PDF)
You can order this, and all my other books, in all formats, directly from my [Author Spotlight] page. The paperback will also be available soon from other online booksellers, search for ISBN 978-1-105-72213-4.
IBM DS3500 Express
The DS3500 is our entry-level block-based device, designed specifically for random I/O workloads. This includes databases, email repositories, traditional business applications, and on-line transactional workloads. Here are the new features:
Dynamic Disk Pooling, similar to what XIV does to reduce disk rebuild times, but using a RAID-6 like approach per chunk of data.
Thin Provisioning using Dynamic Disk Pooling
Asynchronous Logical Unit Access (ALUA) failover
Enhanced FlashCopy, improved scalability, consistency groups and rollback support
VMware API for Array Integration (VAAI) support. This includes Write Same, Extended Copy, and Atomic Test & Set.
The DS3500 replaces the previous models of DS3200, DS3300 and DS3400 models.
The DCS3700 is our entry-level/midrange block-based device, replacing the DCS9900 model, designed specifically for sequential I/O workloads. This includes Big Data analytics, Hadoop, High Performance Computing (HPC), video surveillance, and television broadcasting. It holds 60 drives in a 4U controller enclosure.
Did you miss IBM's Pulse 2012 conference? So did I. Last month, I told you all to [mark your calendars], but wasn't sure if I would be there myself or not.
I was invited to attend Pulse this year, but had to instead go to the Hospital for surgery and spend the week recovering. I thought I made that clear on my last post that I would be spending [the week on my back, with a tube in my arm], but apparently, people missed that subtlety.
The tube was actually connected to the back of my left hand, and I was tempted to take pictures of the entire process, but decided not to, since my gown had no pockets to hold my camera. Perhaps it is better it went undocumented. The less you see of the inner workings of a hospital, as a patient, the better. The whole things was quite a blur.
Despite a few mishaps, I managed to survive the week. Many thanks to Hilda, Dina, Crystal, Marcie, Mike, Joe, Ryan, Sue, Debra, Donna, Modrechai, and the rest of the fine medical staff at St. Joseph's for their hospitality! And of course, many thanks to Mo, my parents and sisters for helping me through the recovery!
Fortunately, for those like me who were unable to go to Las Vegas last week, there is the [IBM Pulse2012 Video Library] with highlights of the keynotes and other sessions during the week.
The keynote was led by Phil Tasker, IBM Business Unit Executive (BUE) for STG Education Programs in Growth Markets, then Joe Screnci, head of IBM Storage Sales for Australia. IBM is in the Top 10 Training Hall of Fame, and conducts over 40,000 classes worldwide, resulting in over 1.3 million student days of instructions. IBM Systems Lab and Training technical hosts over three dozen conferences like this one every year.
Next was Clod Barrera, Distinguished Engineer and Chief Technical Strategist for the IBM System Storage product line. He covered future trends in storage as they relate to IBM's Smarter COmputing initiative.
Storage for the Clouds
Clod Barrera presented this break-out session on Cloud Storage. He covered why clouds matter, the various types and purposes of cloud, technology and architectures, and where IBM is headed to support this trend.
Storage for Cloud computing was $1 Billion USD business in 2010, and is expected to grow 32 percent CAGR through, compared to 3.8 percent for non-cloud storage. Clod estimates that 10 to 15 percent of all storage will be in cloud deployments by 2015. Of this storage, analysts expect 50 percent in private clouds, and the other 50 percent in public clouds. For private clouds, clients are looking to "Cloudify" their existing IT infrastructures. For public clouds, the projects are mostly green field.
IBM is also looking to the "arms dealer" of choice for Telcos and other companies looking to launch their own Cloud Services. IBM has a Cloud Services Provider Platform (CSP2) specifically to provide all the tools and technologies needed to make this possible.
Last month, IBM launched several new solutions for Cloud. The IBM Starter Kit for Cloud will help existing IT environments adopt cloud technologies. The IBM Service Agility Accelerator for Cloud is available for more advanced deployments. IBM Service Delivery Manager (ISDM) integrates a collection of software to provide complete integrated service management. IBM CloudBurst provides an integrated hardware-and-software stack for both x86 and POWER chipsets.
Multi-tenancy is also a big issue, and this varies depending on deployment model: IaaS, PaaS, or SaaS. Multi-tenancy is needed to help divide up management tasks, and to ensure that shared resources are paid for and meet SLA requirements accordingly.
Clod feels there are good reasons to use high performance, transactional SAN storage for VMware environments, versus NAS which many people consider simpler to deploy. IBM is also active in open standards, including SNIA's Cloud Data Management Interface [CDMI].
Journey to the Private Cloud
Gary Luke from Brocade provided this session on IBM's SAN384B-2 and SAN768B-2 SAN directors. Brocade is one of IBM's suppliers for SAN switches, and thanks to TRILL being adopted last August by IETF, supports multi-hop FCoE configurations! However, Gary did not talk about FCoE, but rather native FCP and FICON support in these new directors.
According to VMware, only 30 percent of x86 workloads are virtualized by any hypervisor. Gary feels that server virtualization and the use of Solid-State Drives (SSD) in disk arrays are driving existing 8 Gbps SAN to upgrade to 16 Gbps. Gary feels that Fibre-Channel based SANs are best positioned to handle unpredictable peaks in a 24-by-7 world.
The SAN384B-2 can house up to 256 ports (8 Gbps) or 192 ports (16 Gbps) in four slots, 9U chassis. The SAN768B-2 can handle twice these, in a 12U chassis. The nice thing about the 16Gbps ports is that they can auto-negotiate down to 10, 8, 4 and 2 Gbps. This is far better than typical N-2 support, often referred to as the speeds supported, such as 4/2/1 and 8/4/2. An upcoming FOS release will allow people with previous generation SAN384B-1/SAN768B-1 directors to move their 8Gbps blades over to the new SAN384B-2/SAN768B-2 generation models.
Since most CWDM and DWDM only support maximum 10 Gbps FC and 10GbE, Brocade's 16Gbps can automatically drop down to 10 Gbps for direct attachment to CWDM/DWDM, rather than having a step-down box normally required.
A major advancement is the change from copper to optical "Inter-Chassis Links" (ICL). Unlike Inter-switch links (ISL) that use up SAN ports on each box, the ICL is faster, more efficient and does not consume ports. Normally, clients would connect two directors together, but now you can connect up to six chassis together! For example, you can have four SAN368B-2 connected to your host servers, ICL attached to two SAN768B-2, that are then connected to your disk and tape storage devices. The fiber optic ICL allow for up to 50 meters distance. Combining six chassis together would allow the complex to support over 3,000 ports (8 Gbps) or 2,300 ports (16 Gbps).
The SAN384B-2 and SAN768B-2 supports "virtual SAN" logical switches, traffic isoliation (TI) zones, fabric-assigned WWNNs, and fabric-based QoS.
Lastly, Brocade offers a free utility called [SANhealth] that will gather data from your b-type, m-type and even Cisco MDS-based SAN. The data can then be sent to Brocade for analysis, and Brocade will then email back some nice Visio graphs, spreadsheets and other analysis results on the health of your SAN.
IBM wins lots of awards, but this time is unique: [IBM and Fox Networks Group have jointly won an Engineering Emmy® Award] for Innovation from the Academy of Television Arts & Sciences. According to the Academy, by improving the ability of media companies to capture, manage and exploit content in digital form, IBM and Fox have fundamentally changed the way that audio and video content is managed and stored. Here's an excerpt from the IBM Press Release:
"By standardizing technologies in this way, Fox can now use open-standard, file-based tape in all aspects of production, post-production and distribution functions – displacing costly proprietary tape formats and/or disk subsystems. This provides media companies with the consumer equivalent of having their entire library of DVDs online and available at any time, and the ability to go to a specific scene, in any one of the movies, in an instant.
In the early stage of the technology initiative, the IBM/Fox team applied IBM-patented technologies invented by IBM Research for high-speed data movement. They also integrated traditional broadcast transport and encoding standards with IT industry open standards. This allowed either Standard Definition (SD) or HD programming to be available in real time for digital recording and repurposing -- with improved economics."
Unfortunately, people didn't like the name, but they loved the acronym, so it was renamed to Linear Tape File System. IBM offers LTFS single-drive edition on its LTO-5 and TS1140 tape drives, and LTFS library-edition across all of its tape libraries. Since everyone hates proprietary vendor lock-in, IBM has graciously shared LTFS as an open source standard with the rest of the Linear Tape Open consortium.
(Note: I was not there at the awards ceremony. The pictures were taken by Ed Childers, David Pease and Rainer Richter of each other. Additional photos are available on this [Flicr photo album].)
(1) Rainer Richter, Media Technology Market Partners LLC [MTMP], presenting the Emmy to Steve Canepa, IBM General Manager for Media and Entertainment industry. MTMP is an IBM Business Partner that offers integrated solutions for LTO and LTFS, consulting, services, and technology to the media and entertainment industry…
(2) Ed Childers, IBM manager of the Tape Drive Development team, holding the Emmy. Fellow IBM blogger Steve Hamm credits Ed on coming up with the idea for LTFS seven years ago, in his blog post [Coding and Loading in Las Vegas: How a Team of IBM Researchers Helped Transform the Way Video is Stored]. Ed wanted to make tape storage easier to use and to integrate it into the workflow of networks and studios, and suggested using an indexing system that would allow people to write software that would make video more accessible.
(3) David Pease, IBM Senior Technical Staff Member from the IBM Almaden Research Center, holding the Emmy. Along with Lucas Villa Real (IBM Brazil) and Michael Richmond (IBM Almaden), David and his team were able to come up with a working prototype in just four months. Michael discusses this in his posts [Tape? Does anyone care about Tape anymore?"] and [the Emmy goes to... LTFS].
Of course, Technology is only worthwhile if you put it to use. Our friends at FOX initially partnered with IBM to develop this video archive solution for the National Football League (NFL). If there is one place that "re-purposes" a lot of video footage, it is sports television. The technology proved so useful that FOX has since expanded it to other types of programming.
I have arrived safely to San Francisco, and was able to check-in at the hotel, pick up my registration badge for Oracle OpenWorld 2011, and attend the first keynote session. This is the largest Oracle OpenWorld event to-date, with over 45,000 attendees from 117 different countries. There are 520,000 square feet of exhibition floor, and over 2,400 educational sessions. The conference is spread across the different buildings of the Moscone center, as well as nearby hotels. On average, attendees will walk seven miles during the week.
Larry Ellison was the keynote speaker for this first kick-off session. He focused almost exclusively on server and storage hardware. He feels that business is all about moving data, not doing integer math.
At the beginning of 2011, Oracle had only sold about 1,000 Exadata, but they have a sales target to sell an additional 3,000 Exadata boxes by year end.
The Exadata offers up to 10x columnar compression, and has 10x faster bandwidth (40Gbps Infiniband versus 4Gbps FCP). If you have a 100TB database, it would take up only 10TB of disk with this approach. He claims that the 90TB of disk you don't have to buy can then be used to buy more DRAM and/or Flash SSD.
(Realistically, since SSD is 15x more expensive than spinning disk, you can only purchase about 6TB of Flash for the 90TB you save on disk!)
Larry claims the design point for Exadata and Exalogic was to offer a system that was more powerful than IBM's fastest P795 computer, but cheaper than commodity x86 hardware. His secret is to "Parallel everything" for faster performance, and no single points of failure (SPOF). Exadata offers up to 10-50x faster query, and 4-10x faster OLTP. To keep costs low, Exadata uses all commodity hardware except the Infiniband. He cited various customer examples:
A company replaced 36 Teradata with 3 Exadata and result was application was 8x faster.
Banco Chile 9x faster than previous system
Deutsche Post 60x faster
Sogetti gets 60x faster backups.
French bank BNP Paribas 17x faster and no change to applications.
Proctor & Gamble 18x faster
Merck 5x faster
Turkcell 250TB compressed to 25TB, 10x faster
The problem was that in each example, he said what it was compared against was the old previous system, which varies and could have been an older Sun system, or an old system from HP, IBM or Dell. Perhaps it was a freudian slip, but Larry mistakenly said "Paralyze" your applications, when he probably meant to "Parallelize".
Of all their 380,000 Oracle customers, 70 percent have SPARC/Solaris and/or Linux. Last week, Oracle announced the new SPARC-T4, which Larry claimed was 5x faster than the previous SPARC-T3. Larry feels that for the first time ever, a non-IBM CPU can challenge the long-standing rein of the IBM POWER series processor. Larry admitted that the IBM POWER7 chip actually did some tasks faster than the SPARC-T4, so his work is not yet done, but they plan to offer a new SPARC-T5 next year that will be 2x better than the SPARC-T4.
Larry compared the I/O bandwidth of serv ers based on SPARC-T4, compared to POWER7, and found that the SPARC-T4 has double the I/O bandwidth, for a cost that was only about 1/4 the cost of a mainframe. IBM offers both. POWER7-based servers for CPU-intensive workloads, and System z (S/390)-based systems for I/O-intensive workloads. Larry feels that even though POWER7 is superior than SPARC-T4 for mathematical calculations, all business applications are focused on I/O-bandwidth to move data, not computations.
Larry claims the new SPARC-T4 can do 1.2 million IOPS. He uses 40 Gbps Infiniband instead of traditional SAN-attached FCP solutions.
A new "box" called Exalytics, combines their commodity hardware platform with a hueristic adaptive in-memory cache, their latest "me-too" solution that compares with what IBM already offers in [IBM SolidDB]. In fact, their me-too is not even internally developed, but rather the result of an acquisition of a company called "Times Ten". I thought it was interesting that the only piece of Oracle software mentioned during Larry's 90-minute speach, was this piece of acquired technology. The new Exalytics product run on a small rack and grow, analyzing relational data, non-relational OLAP, as well as unstructured documents. The result is what Larry called "the Speed of Light".
He also mentioned that Bob Shimp would kick-off the Cloud later in the week. Given that Larry himself thought that Cloud was a stupid, over-marketed term that nobody has deployed over the past few years, to a complete believer, claiming that over 20 live demos will be given this year on Cloud.
Perhaps the funniest quote was his motivation to use Infiniband as the interconnect
"Ethernet was invented by Xerox when I was a child."
-- Larry Ellison
Here are some sessions that IBM is featuring on Monday. Note the first two are Solution Spotlight sessions at the IBM Booth #1111 where I will be most of the time.
IBM Cloud Computing Solutions for Oracle
10/03/11, 10:30 a.m. – 11:00 a.m., Solution Spotlight, Booth #1111 Moscone South
Presenter: Chuck Calio,Technical Strategist, IBM Systems & Technology Group
