In the future, we are going to manage minutiae to smithereens

The Environmental Protection Agency (EPA) wants to get in front of the energy consumption estimates for data centers in the next several years and find a way to rate technology products and data centers for their energy efficiency.

I attended a meeting today about the future of energy standards for storage products. This is fairly serious work and it involves the DMTF, Green Grid and SNIA - three groups that are working to identify the measurements and methods that will eventually lead up to an EPA Energy Star label for storage products.

It's a messy process to be sure, but there are a lot of smart people working on this. The challenge is coming up with measurements that can be applied across a large set of products and configurations and representing an amazingly diverse set of workloads. A zillion decisions need to be made about what gets measured, how it gets measured, how that data is stored and and compiled and eventually interpreted. The three industry groups involved are now trying to figure out how to divide the work so they can be as efficient as possible.

From an operating perspective, it looks like there will be a lot more monitoring of system operations and health in the future. It sort of reminds me of the transformation we've seen in cars and trucks over the last 50 years. You can look under the hood of a 1965 pickup truck and see all the belts, hoses, sparkplugs, wires and everything else you might want to inspect and change. If you look under the hood in a new car today, its hard to see what's what with all the hoses and things that manage the efficiency and output of the engines.

Tomorrow's servers and storage won't have hoses, belts and tubes shoved in their cases, but they will use a fair amount of processing power to monitor and manage their environmentals. Processing power not used for data processing, but for running as efficiently as possible.

Dell OpenManage SUU now works with ESX

This post first appeared on the Inside IT blog (at Dell).

One of my favorite bloggers in Bob Plankers, the Lone Sysadmin. With all the excitement of getting this blog launched on Friday, I missed his post on the OpenManage Server Update Utility (version 5.4.0), which now works on ESX Server 3.5. Bob is always churning up interesting info that I think people that come to this blog would appreciate.

Thanks for passing this along, Bob. (and u haf 2 lik hiz lolkatz tagglin)

Crash consistent snapshots of Exchange

The conversation below recently was posted to an older post in this blog. I thought it was a good one, so I copied it below. Stan is the external commenter and Darren Miller is an excellent product guy and SME who responded to Stan's questions.

FWIW, Darren has a couple upcoming online Demos that I recommend, including today 4/17 at 3:00PM Eastern
____________

In the past I was advised that Equallogic SAN replication was not "crash consistent", that is since many server apps hold data in RAM buffers/cache , the data on the SAN is not complete, thus replication to other SAN's sends incomplete data. To workaround this problem the SAN needs software running in conjunction with the server to sync the data in the buffers/cache to storage.

Does Equallogic do this now? How does it and where could I read the details of this? I'm interested in how crash consistent Exchange, SQL, windows AD and assorted VMware vm's with custom apps are.

Thanks.

Stan,

To address your questions and concerns, Auto-Snapshot Manager (ASM), is included in the Dell EqualLogic Host Integration Tools Kit. ASM integrates with Microsoft VSS and the EqualLogic VSS provider service to create application consistent copies (Smart Copies) of data on Win server 2003 systems.

The way it works is you would install the Host Integration Tools kit (downloadable at www.equallogic.com) on your server making sure you select Auto-Snapshot Manager as part of the install package. Once installed you authenticate the host to the PS Series SAN through CHAP authentication. Once all configured, ASM will be able to protect data on the host.

ASM facilitates the volume protection capabilities of the PS Series SAN like snapshots, clones, and replicas but integrates directly with the application through VSS to ensure data consistency. You as the user determines what type of Smart Copy to create beit snapshot, clone or replica.

For more information on how you would use ASM with SQL Server databases there is a detailed technical report describing this functionality on equallogic.com.

In terms of VMware protection, there is a lot of information out on the site with different examples of how to protect your VMware environment on a PS Series SAN.
