Greg and 3PAR's Marc Farley did an "ambush" interview with the folks at the IBM booth at SNW, including Paula Koziol about Twitter, and [Rich Swain] about IBM's latest SONAS product. Here is their post [Storage Monkey business with IBM]:
You can learn more about SONAS from my post [More Details about IBM Clustered NAS]. SONAS is based on software that has been available since 1996, on commodity off-the-shelf server and storage systems, but building a complete system was left as an exercise to the end-user, which many of the top 500 Supercomputers have done.
Back in November 2007, IBM announced Scale-Out File Services (SoFS) which was a set of IBM Global Technical Services to build a customized solution from the software and a set of servers, disk and tape storage. Customized configurations were done for a variety of workloads from Digital Media to Scientific Research High Performance Computing (HPC). Last year, SoFS was renamed to IBM Smart Business Storage Cloud (SBSC).
This year, IBM was able to package all of the software and hardware into an easy to order machine-type model that has everything cabled and ready to use. This is what SONAS is today.
Well, it's Tuesday again, and you know what that means? IBM Announcements!
New Nearline expansion enclosures for FlashSystem V9000 and SAN Volume Controller (SVC)
The new 12 Gb SAS expansion enclosure expands total capacity and delivers a tiered data solution. Each LFF expansion enclosure supports twelve 3.5-inch 8 TB NL-SAS drives. Up to two expansion enclosures are supported by a FlashSystem V9000 or SVC controller pair, delivering up to twenty-four drives and 192 TB of raw capacity. The capacity can be compressed up to 5x (80 percent savings) using IBM Real-time Compression.
IBM Spectrum Control and IBM Virtual Storage Center V5.2.10 release
IBM Spectrum Control continues its quarterly continous delivery model with version 5.2.10 release. This is also included in all variants of IBM Virtual Storage Center which bundles IBM Spectrum Control with IBM Spectrum Virtualize products. New features include:
View more details about capacity growth over time for storage systems, pools, volumes, fileset, and file systems. This helps capacity planners to plan for future purchases and procurement.
Aggregate basic information across multiple Spectrum Control servers into a single place, rolling up information was temporally removed in Spectrum Control V5.2.8 and is now available in the web-based GUI for the first time. This is intended for clients to manage multiple data center sites, but can also be used to Cloud Service Providers and Managed Service Providers to generate reporting across a group of clients.
Compare the workload and performance characteristics of IBM SAN Volume Control and IBM Storwize systems against best practice performance guidelines. This is especially useful synergy for the IBM Virtual Storage Center bundles.
Export performance data for storage systems and fabrics using a new Create Performance Support Package wizard. This is helpful in case you observe a performance problem with your IBM storage system, and the IBM support for that device would like to receive the measured performance statistics for further analysis. In the same manner that IBM Spectrum Control drastically reduces troubleshooting time for clients, it is also proven useful for IBM support teams.
Understand how the capacity of storage systems is used when storage virtualization is implemented in the environment, by looking at the information about virtualized and non-virtualized capacity. This allows storage administrators to show upper management how their investment in IBM Spectrum Virtualize (SVC, Storwize, etc.) has returned on investment.
Launch the IBM Spectrum Scale GUI from IBM Spectrum Control to deliver an even better integration of the two products.
It is hard to believe I was the "Technical Evangelist" for SAN Volume Controller when it launched in 2003. That was 13 years ago! Since then, a variety of products using the shared codes base (IBM Spectrum Virtualize) have launched, including IBM Storwize family and IBM FlashSystem V9000 mentioned above. The new IBM Spectrum Virtualize Software V7.7 delivers the following improvements:
Reliability, availability, and serviceablility with NPIV host port fabric virtualization. This is actually pretty cool feature. NPIV stands for "N-port ID Virtualization". Every Spectrum Virtualize port has an N-port ID, and if one node fails, multi-pathing software must scramble to look up its partner node and re-direct traffic to the ports of that other node. With NPIV, the partner node takes on the N-ports of both its own node, as well as the failed node, and handles all the traffic, and then gives back the N-ports back to the other node when it is back up and running.
Distributed RAID (DRAID) support for encryption. IBM added support for distributed RAID-5 and RAID-6 in the previous release, but at the time did not include the built-in encryption feature for these new kind of RAID ranks. Now it supports encryption.
Graphical User Interface (GUI) enhancements to manage your IP-based quorums. Previously, if you had a two-site configuration like Stretched Cluster or HyperSwap, best practices would require a third location as "tie breaker". Thus, people ran fiber optic cables from both sites to a third location, with a small disk system in a closet somewhere. The IP-based quorum is a little Java program you can run on any system, and so long as both sites have LAN or WAN access, serves the same role.
Graphical User Interface (GUI) enhancements to run the "Compresitmator" tool. The Comprestimator tool can run against existing volumes (vDisks) to identify estimated compression savings.
Flexibility Virtualization of iSCSI-attached and Fibre Channel-attached external Storage arrays. Previously, only Fibre Channel (FCP and FCoE) back-end devices could be virtualized. Initially, this will support iSCSI virtualization of IBM Storwize and Dell EqualLogic.
Performance with 64 GB read cache. The software code was enhanced to take advantage of 64-bit memory addressing to support larger read cache.
Software licensing metrics to better align the value of SVC software with Storage use cases through Differential Licensing, based on Storage Capacity Unit (SCU). The licensing for SVC has base and compression license based on the back-end (managed physical usable capacity), and then various features that are based on the subset of front-end capacity (virtual volumes). The new Differential Licensing applies SCU to the back-end (base license and compression). The front-end features continue to be TB-based.
IP Link compression to improve usage of IP networks for remote-copy data transmission
Differential Licensing based on Storage Capacity Unit (SCU)
Differential licensing based on new concept IBM calls Storage Capacity Unit (SCU). Previously, software was licensed per Terabyte (TB), but that treated all TB the same, from Flash to Nearline disks. The new license method takes storage media into three categeories:
1 SCU equals 1.00 TB of Flash and Solid-State Drives (SSDs), and any other storage not listed in the categories below.
1 SCU equals 1.18 TB of 10K and 15K rpm drives, such as Serial Attached SCSI (SAS) Drives and Fiber Channel Drives, as well as systems using "Category 3" (Nearline or SATA drives) with advanced architectures to deliver high-end storage performance, such as IBM XIV Storage System, HP 3PAR or Infinidat .
1 SCU equals 4.00 TB of 7200 rpm Nearline SAS (NL-SAS) and Serial ATA (SATA) Drives
This new licensing is experimental. I would be interested in your feedback.
Yesterday, I asked if you were prepared for the future? The future is now. Today, IBM announced its["New Enterprise Data Center"] vision and strategy which spans software, hardware and services in dealing withthe latest challenges that our clients are faced with today, or will face sooner or later this century.
Here's an excerpt:
Align IT with business goals These changes demand that IT improve cost and service delivery, manage escalating complexity, and better secure the enterprise. And aligning IT more closely with the business becomes a primary goal. The new enterprise data center is an evolutionary new model for efficient IT delivery that helps provide the freedom to drive business innovation. Through a service oriented model, IT will be able to better manage costs, improve operational performance and resiliency, and more quickly respond to business needs. This approach will deliver dynamic and seamless access to IT services and resources, improving both productivity and satisfaction.
IBM's Vision for the New Enterprise Data Center The new enterprise data center can improve the integration of people, process, and technology in your business to help you improve efficiency and effectiveness. As you implement a new enterprise data center strategy, your infrastructure becomes open, efficient, and easy to manage. And your IT staff can move from a focus on fixing IT problems to solving business challenges. Ultimately your processes become standardized and efficient, focused on business needs rather than technology.
A lot was announced today, so I will give a quick recap now, and cover specific areas over the rest of the week.
IBM System z10 Enteprise Class
IBM introduces its most powerful mainframe. Before you think "Wait, that's a mainframe, that doesn't apply to me"stop to consider all that IBM has done to make the mainframe an "open system" without sacrificing security oravailability:
Open standard connectivity, including TCP/IP and now 6Gbps Infiniband and 10GbE Ethernet.
Unix System Services. Yes, z/OS is certified to provide UNIX interfaces for today's applications.
HFS and zFS file systems that can be mounted, shared, and used by traditional z/OS applications and JCL.
Linux and Java. Many of today's largest websites are run on mainframes behind the scenes.
Extreme bandwidth. The z10 EC handles up to 336 FICON channels (4Gbps) for large data processing workloads
The z10 EC is as powerful as 1,500 x86 (such as Intel or AMD) servers, but consumes 85 percent less floorspace and85 percent less energy. (They should put a "green" stripe down the front of this box just to remind everyone how energy efficient this server really is!) For more on the z10 EC, see the[Press Release].
Enhanced IBM System Storage DS8000
With the XIV acquisition taking the role as the best place to put unstructured files for Web 2.0 applications,the IBM DS8000 can focus on its core strength, managing databases and online transactions for the mainframe.There's enough here to justify its own post, so I will cover this later.
IT Service Management Center for z (ITSMCz)
Trust me, I don't make up these acronyms. IT Service Management are the policies and procedures for managingan IT environment, such as following the best practices documented in the IT Infrastructure Library (ITIL).In the past, IBM tools have focused on Linux, UNIX and Windows on distributed servers, but today ITSMCz bringsall of that to the mainframe! (or perhaps more correct to say "brings the mainframe to all that"!)
IT Transformation & Optimization - Infrastructure Strategy and Planning services
I don't make up the names of our service offerings either. However, one thing is clear, it is time for peopleto re-evaluate their current data center, and come up with a new plan. The average data center is 15 years old.According to Gartner Group, more than 70 percent of the world's "Global 1000" organizations will have to make significant modifications to their data centers in the next five years. IBM can help, and is rolling outa new set of services specifically to help clients make this transition, to better align their IT to their business strategies.
Economic Stimulus Package
IBM borrowed this idea from the U.S. government. IBM Global Financing is offering special terms and ratesfor new equipment installed by December 31 this year.

Last year, I took a different approach. I decided to NOT publicize my resolutions to see if that allowed me to stick to them better. Here is what I had resolved for 2010:
The recession took quite a hit on my investments and retirement plans in 2009, so in 2010 I decided to increase my savings rate, and diversify my portfolio. I consider this one a success, with special thanks to the financial planners at Fidelity Investments for their assistance in this area. This was not a matter of sticking to a strict budget as much as not wasting money on so many expensive, frivolous things.
Publish "Inside System Storage: Volume II"
Yes, I finally got my latest book published last October, a follow-on to my 2007 hit "Inside System Storage: Volume I". I have already begun working on Volume III, so I consider this one a success.
Quit Exercising at the Gym
From 2003 to 2009, I had worked out consistently at my gym three times a week for an hour, under the supervision of a personal trainer, with 20 minutes of cardio work-out on a treadmill followed by 40 minutes of weight lifting with kettle-bells, free weights and resistance machines. During that time, I did not gain muscle mass nor lose body fat. Rather than admit their failure, my personal trainers indicated this is merely a "plateau". Armed with the Time article [Why Exercise Won't Make You Thin], I decided to save thousands of dollars in 2010 by discontinuing my gym membership and expire my contract with my personal trainer. End result? I was two pounds lighter after 12 months, so I consider this one a success.
Re-Decorate my Living Room
With all the money I saved, I resolved to re-decorate my living room. I hired a professional interior decorator, bought new furniture, and had the entire room re-painted to new colors. This also means keeping the room uncluttered, which I have managed to do so far. So, this one is also a success.
Learn Cloud Computing
This last one was work-related. Every year, IBM asks its employees to document their "Personal Business Commitments", or PBCs, which then forms the basis of your year-end appraisal. IBM is what the industry calls a "Results-Oriented Work Environment" [ROWE]. These PBCs are an opportunity to identify areas to stretch and grow, broaden your skills and strengthen your expertise. I was able to get access to IBM's cloud computing offerings to get hands-on experience, as well as research this topic on various fronts so that I could provide advice to clients and make presentations at various briefings and events. While there is still much more to learn, I consider this a success.
So, while I seem to have been more successful keeping my resolutions by not making them public up front, I think the more important pattern is that when I made many resolutions, I had only a 60 to 80 percent success rate, but when I had fewer, I was more likely to keep them all and be less stressed about it. This could also be psychological, in that feeling that you have completed 60 to 80 percent allows you to forgive yourself for not keeping some of the more difficult resolutions. Therefore, this year, I have decided to focus on a single resolution, to reduce my body fat percentage.
Rather than make you wait 12 months for my results, I plan to provide periodic updates in this blog on my progress. Over the vacation break, I bought and read Tim Ferriss' book [Four Hour Body]. Mo and I are in this together, and we have started Tim's [Slow-Carb diet] last Sunday. My doctor has advised me on which vitamins and supplements to take. Rather than go back to the gym, I will just focus on walking at least 20,000 steps per week, which works out roughly to 10 kilometers.
Please welcome new IBM blogger Keith Stevenson, his new blog is called [Infovore]. He gives his take on the big October 20 announcement we had this week,
and will continue to cover topics related to storage of information.
Some people find it surprising that it is often more cost-effective, and power-efficient, to run workloads on mainframe logical partitions (LPARs) than a stack of x86 servers running VMware.
Perhaps they won't be surprised any more. Here is an article in eWeek that explains how IBM isreducing energy costs 80% by consolidating 3,900 rack-optimized servers to 33 IBM System z mainframe servers, running Linux, in its own data centers. Since 1997, IBM has consolidated its 155 strategic worldwide data center locations down to just seven.
I am very pleased that IBM has invested heavily into Linux, with support across servers, storage, software andservices. Linux is allowing IBM to deliver clever, innovative solutions that may not be possible with other operating systems. If you are in storage, you should consider becoming more knowledgeable in Linux.
The older systems won't just end up in a landfill somewhere. Instead, the details are spelled out inthe IBM Press Release:
As part of the effort to protect the environment, IBM Global Asset Recovery Services, the refurbishment and recycling unit of IBM, will process and properly dispose of the 3,900 reclaimed systems. Newer units will be refurbished and resold through IBM's sales force and partner network, while older systems will be harvested for parts or sold for scrap. Prior to disposition, the machines will be scrubbed of all sensitive data. Any unusable e-waste will be properly disposed following environmentally compliant processes perfected over 20 years of leading environmental skill and experience in the area of IT asset disposition.
Whereas other vendors might think that some operational improvements will be enough, such as switching to higher-capacity SATA drives, or virtualizing x86 servers, IBM recognizes that sometimes more fundamental changes are required to effect real changes and real results.
In addition to creating the Dilbert cartoon, Scott Adams has a blog, which sometimes is quite serious,and other times quite funny. The anticipated 30x cost of "Flash Drives" for Enterprise disk systems reminded meof one of Scott's articles from November 2007 titled [Urge to Simplify].Here's an excerpt:
Now the casinos have people trained, like chickens hoping for pellets, to take money from one machine (the ATM), carry it across a room and deposit in another machine (the slot machine). I believe B.F. Skinner would agree with me that there is room for even more efficiency: The ATM and the slot machine need to be the same machine.
The casinos lose a lot of money waiting for the portly gamblers with respiratory issues to waddle from the ATM to the slot machines. A better solution would be for the losers, euphemistically called “players,” to stand at the ATM and watch their funds be transferred to the hotel, while hoping to somehow “win.” The ATM could be redesigned to blink and make exciting sounds, so it seems less like robbery.
I’m sure this is in the five-year plan. Longer term, people will be trained to set up automatic transfers from their banks to the casinos. People will just fly to Vegas, wander around on the tarmac while the casino drains their bank accounts, then board the plane and fly home. The airlines are already in on this concept, and stopped feeding you sandwiches a while ago.
Perhaps EMC can redesign its DMX-4 to "blink and make exciting sounds" as well. The Flash Drives were designedfor the financial services industry, so those disk systems could be directly connected to make transfers between the appropriate bank accounts.
It's that time again to think about [New Year's resolutions]! This fine tradition dates back 4000 years
to early Babylonians, with the most popular resolution back then was to return borrowed
Resolutions can be to work toward a specific goal, start doing something, or change your
habits to do something more often, or less often, than last year. Jim Collins from
37Signals suggests a [Stop Doing List]. Colin Beavan (aka [No Impact Man]) took this idea to the
extreme, giving up a year of electricity, coffee and toilet paper, and a bunch of other
things, in an effort to minimize his environmental impact.
This one was easy. Nearly all of my friends and family live in Tucson, so spending more
time merely involves spending less time out of town. With the economic meltdown of
2008, IBM set down strict travel restrictions, so I only traveled 11 weeks in 2009.
Enjoy Life More
I have mixed feelings on this one. The four hardest hit areas of the current economic
recession were southern Florida, southern Michigan, southern California and southern
Arizona. Last year, I had friends that lost their job, their home, their business, or
their battle with cancer. Trying to enjoy life while your friends are walking around
like zombies after nuclear winter just doesn't feel right.
Learn Something New
I was able to keep this one, in an unexpected way. Shortly after making this
resolution, I was asked to teach young kids the "C" programming language so they could
program LEGO Mindstorms robots. While I already know "C" in general, I had to learn to
build the robots and program the interface for the robot "brick" in order to teach
others. Sometimes, the best way to learn something new, is to offer to teach it to
others. This was a deeply rewarding way to give back to the community.
Make Tucson a better place, and enrich the lives of its residents
In addition to helping teach kids to build robots, I spent hundreds of hours and
thousands of dollars to support local Tucson organizations this year. Did it help? It
is hard to say. For example, you can spend an entire day sorting cans for the community
food bank, only to learn that this will all be consumed in a matter of days. At least I
will be paying less taxes!
Get better organized
This has been an ongoing struggle, but I made progress in 2008 and 2009. Last year, I
purchased a T-mobile G1 smart phone with Google and I have been using this as my
organization tool. It syncs up with my Gmail, Google Calendar, Google Contacts,
Remember the Milk, Delicious, and other sites I use. It certainly works better for me
than my past attempt using a [Hipster PDA].
Should people make their resolutions public? Derek Sivers cites research indicating
that [announcing your plans makes you less
motivated] to complete them. Given the long waits we saw between when storage
vendors like EMC announce some new feature to when it is actually delivered, there might
be a lot of truth to that. So, this year, I will do things differently and NOT make
public any New Year's resolutions for 2010.
