Wednesday at EMC World was a session packed day to be sure.
I started my morning with CLARiiON Rebuild Settings and Data which was an in depth look at how exactly the CLARiiON systems handle rebuilds, and how long various rebuilds take. In addition we went into detail as to how the CLARiiON will not see that a disk is going to fail, and instead of waiting for it to fail and then having to rebuild it will actually copy the data from the disk ahead of time to a hot-spare then mark the disk as failed so that it can be replaced before the disk actually fails there by providing you with no point in time where your data is unprotected.
Another session went through the changes to the EMC PowerPath product and all the new features they are building into PowerPath such as the encryption of data when it leaves the server on its way to the disk.
Another session went through some tuning tips an tricks for getting the best performance from the EMC CLARiiON product. These include the strip size, cache settings at both the LUN and SP level.
The night ended with the Billy Crystal performance. I figured that the show would be funny. I was wrong, it was hilarious. Like everyone else I’ve seen Billy Crystal on TV and in Movies and thought he was funny, but in person he was probably the best comedy performance that I had ever seen.
