For those who want to meet me in person, there are two opportunities coming up in December.
Data Center Conference, December 1-4
Once again, I will be blogging from Ceasar's Palace Las Vegas at this year's [Data Center Conference 2009]! Last year's conference was a blast, and this one looks to be quite exciting. IBM is again a premier sponsor. Scheduled to speak are the following IBM executives:
Helene Armitage, the new General Manager of System Software, on "IT-Wide Virtualization, A Prerequisite for a Truly Dynamic Infrastructure"
Steve Sams, the VP of Sites and Facilities, on "Data Center Actions Your CFO Will Love"
Barry Rudolph, the VP of System Storage, on "Meeting the Information Infrastructure Challenge"
We will also have an IBM booth at the Solutions Showcase, showing off the latest in Cloud Computing,
Service Management, Information Infrastructure, and Workload-optimized systems. You will be able to schedule one-on-one sessions with IBM executives and subject matter experts. Best of all, we will have on display a Portable Modular Data Center [PMDC] that can hold a fully operational data center in a standard [20 foot shipping container].
IBM Virtualization and Consolidation Briefing, December 15
This is being done "open house" style. If you can get yourself to the IBM Tucson Executive Briefing Center, IBM will provide you breakfast, a series of presentations, lunch, and then even more presentations. Your stomach and brain will be full by the end of the day. Here is a list of the presentations:
Well, it's Tuesday again, and we have more IBM announcements.
XIV asynchronous mirror
For those not using XIV behind SAN Volume Controller, [XIV now offers native asynchronous mirroring] support to another XIV far, far away. Unlike other disk systems that are limited to two or three sites, an XIV can mirror to up to 15 other sites. The mirroring can be at the individual volume, or a consistency group of multiple volumes. Each mirror pair can have its own recovery point objective (RPO). For example, a consistency group of mission critical application data might be given an RPO of 30 seconds, but less important data might be given an RPO of 20 minutes. This allows the XIV to prioritize packets it sends across the network.
As with XIV synchronous mirror, this new asynchronous mirror feature can send the data over either its
Fibre Channel ports (via FCIP) or its Ethernet ports.
The IBM System Storage SAN384B and SAN768B directors now offer [two new blades!]
A 24-port FCoCEE blade where each port can handle 10Gb convergence enhanced Ethernet (CEE). CEE can be used to transmit Fibre Channel, TCP/IP, iSCSI and other Ethernet protocols. This connect directly to server's converged network adapter (CNA) cards.
A 24-port mixed blade, with 12 FC ports (1Gbps, 2Ggbs, 4Gbps, 8Gbps), 10 Ethernet ports (1GbE) and 2 Ethernet ports (10GbE). This would connect to traditional server NIC, TOE and HBA cards as well as traditional NAS, iSCSI and FC based storage devices.
IBM also announced the IBM System Storage [SAN06B-R Fibre Channel router]. This has 16 FC ports (1Gbps up to 8Gbps) and six Ethernet ports (1GbE), with support for both FC routing as well as FCIP extended distance support.
With the holiday season coming up at the end of the year, now is a great time to ask Santa for a new shiny pair of XIV systems, and some extra networking gear to connect them.
Well, I had a pleasant vacation. I took a trip up to beautiful Lake Powell in Northern Arizona as part of a "Murder Mystery Dinner" weekend. This trip was organized by AAA and Lake Powell in association with the professionals at [Murder Ink Productions] out of Phoenix.
The trip involved two busloads of people from Tucson and Phoenix driving up to Lake Powell, with a series of meals that introduced all the characters and gave out clues to solve a murder. At the end of the dinner on the last evening, we had to guess who dunnit, how, and why. I solved it, and got this lovely tee-shirt.
More importantly, the trip gave me a chance to read
[The Numerati] by Stephen Baker. The author explains all the different ways that "analysts" are able to crunch through the large volumes of data to gain insight. He has chapters on how this is done for shoppers in retail sales, voters for upcoming elections, patients for medical care, and even matchmaking services like chemistry.com. Like the Murder Mystery Dinner, there are too many suspects and too many clues, but these number-crunchers, which Mr. Baker calls The Numerati, are able to figure out through advanced business analytics.
FTC Notice: I recommend this book. I did not receive any compensation to mention this book on this blog, I did not receive a copy of the book free for this review, and I do not know the author. Everyone in my staff is reading this book, and I borrowed a copy from a co-worker.
If you don't understand how this all works, here is a quick 6-minute [video] on YouTube.
In his Backup Blog, fellow blogger Scott Waterhouse from EMC has yet another post about Tivoli Storage Manager (TSM) titled [TSM and the Elephant]. He argues that only the cost of new TSM servers should be considered in any comparison, on the assumption that if you have to deploy another server, you have to attach to it fresh new disk storage, a brand new tape library, and hire an independent group of backup administrators to manage. Of course, that is bull, people use much of existing infrastructure and existing skilled labor pool every time new servers are added, as I tried to point out in my post [TSM Economies of Scale].
However, Scott does suggest that we should look at all the costs, not just the cost of a new server, which we in the industry call Total Cost of Ownership (TCO). Here is an excerpt:
Final point: there is actually a really important secondary point here--what is the TCO of your backup infrastructure. In some ways, TSM is one of the most expensive (number of servers and tape drives, for example), relative to other backup applications. However, I think it would be a really interesting exercise to critically examine the TCO of the various backup applications at different scales to evaluate if there is any genuine cost differentiation between them.
Fortunately, I have a recent TCO/ROI analysis for a large customer in the Eastern United States that compares their existing EMC Legato deployment to a new proposed TSM deployment. The assessment was performed by our IBM Tivoli ROI Analyst team, using a tool developed by Alinean. The process compares the TCO of the currently deployed solution (in this case EMC Legato) with the TCO of the proposed replacement solution (in this case IBM TSM) for 55,000 client nodes at expected growth rates over a three year period, and determines the amount of investment, cost savings and other benefits, and return on investment (ROI).
Here are the results:
"A risk adjusted analysis of the proposed solution's impact was conducted and it was projected that implementing the proposed solutions resulted in $16,174,919 of 3 year cumulative benefits. Of these projected benefits, $8,015,692 are direct benefits and $8,159,227 are indirect benefits.
Top cumulative benefits for the project include:
Backup Coverage Risk Avoidance - $6,749,796
Reduction in Maintenance of Competitive Products - $1,576,000
Reduction in Existing Tivoli Maintenance (Storage and Monitoring) - $1,490,000
IT Operations Labor Savings - Storage Management - $982,919
Network Bandwidth Savings - $575,196
Standardization - $366,667
Future cost avoidance of addtional competitive licenses - $350,000
These benefits can be grouped regarding business impact as:
$6,456,025 in IT cost reductions
$1,559,667 in business operating efficiency improvements
$8,159,227 in business strategic advantage benefits
The proposed project is expected to help the company meet the following goals and drive the following benefits:
Reduce Business Risks $6,749,796
Consolidate and Standardize IT Infrastructure $4,975,667
Reduce IT Infrastructure Costs $2,057,107
Improve IT System Availability / Service Levels $1,409,431
Improve IT Staff Efficiency / Productivity $982,919
To implement the proposed project will require a 3 year cumulative investment of $5,760,094 including:
$0 in initial expenses
$4,650,000 in capital expenditures
$1,110,094 in operating expenditures
Comparing the costs and benefits of the proposed project using discounted cash flow analysis and factoring in a risk-adjusted discount rate of 9.5%, the proposed business case predicts:
Risk Adjusted Return on Investment (RA ROI) of 172%
Return on Investment (ROI) of 181%
Net Present Value (NPV) savings of $8,425,014
Payback period of 9.0 month(s)
Note: The project has been risk-adjusted for an overall deployment schedule of 5 months."
IBM Tivoli Storage Manager uses less bandwidth, fewer disk and tape storage resources than EMC Legato. For even a large deployment of this kind, payback period is only NINE MONTHS. Generally, if you can get a new proposed investment to have less than 24 month payback period you have enough to get both CFO and CIO excited, so this one is a no-brainer.
Perhaps this helps explain why TSM enjoys such a larger marketshare than EMC Legato in the backup software marketplace. No doubt Scott might be able to come up with a counter-example, a very small business with fewer than 10 employees where an EMC Legato deployment might be less expensive than a comparable TSM deployment. However, when it comes to scalability, TSM is king. The majority of the Fortune 1000 companies use Tivoli Storage Manager, and IBM uses TSM internally for its own IT, managed storage services, and cloud computing facilities.
