Intel IT weighs in on iSCSI

January 30, 2007

The conversation about iSCSI and adoption rates has been going on for some time now and there have been some interesting insights provided by thought leaders in the storage industry.

Unfortunately we have been having this conversation amongst ourselves and because of that, we’re not helping anyone!

Thankfully Sudip Chahal has access to the Intel IT blog and posted his thoughts about actual adoption of iSCSI in a real IT environment. Sudip’s point of view is interesting and is something that the vendors need to pay attention to. He sees iSCSI eventually overtaking Fiber Channel in the same way that ethernet took over token ring and in the same way that ethernet is now taking over the telephone system.

Thanks Sudip!

Any other IT Shops out there have a similar or different opinion?

The storage world is moving today

The Brocade/Mcdata deal is pretty big, both are equal players in the field so it will be interesting to see how Cisco reacts to the new leader. Steve Duplessie has a good write up on the news.

Exchange 2007 on iSCSI Storage

August 3, 2006

Should you deploy Exchange 2007 on iSCSI Storage? That is the big push from Microsoft lately…. Get rid of your unreliable DAS, scrap the expensive SAN, and go with a great iSCSI solution….. In fact, you can use the Microsoft initiator to make it seamless along with the rest of Microsoft’s iSCSI innovations.

The good part is, all of Microsoft’s Exchange 2007 IO reduction claims seem are true and remain true for iSCSI implementations. The hard peice that is not quatified though is managing an iSCSI infrastructure as well as using it effectively in a backup and business continuity story. Let’s also not forget that the Monday morning surge of email (before all of that x64 memory is filled) will have a larger impact on the storage.

Will companies move to iSCSI for their messaging environments? Recent surveys seem to be reporting that iSCSI adoption rates are stagnant if not declining already. Could Microsoft’s big pushes with names like Simple SAN and their push in Exchange 2007 to use iSCSI disks really change this? According to the article at eWeek on the iSCSI adoption rates, customer’s are not moving to iSCSI for management, recovery, and overall satisfaction. They have tried iSCSI and found it didn’t quite meet all of their needs or they found in their initial comparisons that it would not provide a solid long-term solution for them.

I agree that these limitations will make adoption slow for larger companies. Although simply replacing DAS with iSCSI is a great step in the right direction.

An interesting option even though Exchange 2007 is not expected to be supported on NAS, are the new technologies like MPFSi.

Modeling your SAN environment

July 31, 2006

This new functionality from EMC is kind of cool. They have added a new modeling component called SAN Advisor to their ControlCenter suite of tools. It allows you to model fixes and changes to your SAN environment without impacting production. EMC has been making huge strides in this area after the acquisition of SMARTS and has already offered a large suite of leading products in this space.

I am really excited that these kinds of things are coming out and can’t wait until the day we can do things like this on exchange…….. if I change my AD site topology, Exchange 2007’s new routing behavior will now change to route all mail through that new site…… OR if I apply the hotfix 895949, these applications and users will not be able to work.

Also announced today from EMC; their leading storage training curriculum and certification programs are going to be offered through universities and training organizations. This is pretty cool, the training and certification is already high quality, the fact that the delivery expansion is happening like this is a great sign for people who need to get up to speed or want to start in a storage industry career. This is certainly a mark of change in the industry overall, more and more companies use and have a need for highly qualified storage engineers.
