Day Three OOW '09

Well, day three is over and so is the conference for yours truly. We gave away 500 of our new books and got to talk to hundreds of great folks who stopped by the booth. We gave 13 - 10 minute presentations on the new OPERA architecture as well. RIght now I am waiting to head for Atlanta and home.

I was speaking to someone at the booth yesterday and they mentioned attending Tom Kyte's presentation on the best new features of Oracle11gR2. Tom seemed to have said (according to who I was speaking to) that the flash cache feature will be generally available and not just restricted to Sun Solaris and Exadata2. If so that is really good news for folks with convential hard disk based systems. By adding a RamSan10 (225 gig) or RamSan20 (450 gig) to their servers folks could have immense flash caches operating at flash memory speed for frequently used data. Thus, by upgrading to 11gR2 and incorporating the 10 or 20 into their systems they could experience extreme performance improvement with n changes to their application!

I was also talking to someone elxe about the Exadata2 and how it would be interesting to put the Exadata processors on top on one of our RamSan620s and they asked something interesting, why put Flash on top of Flash? (flash cache on top of flash drives) which actually is a good question. It seems to me on second thought that most of the Exadata2 improvements where to compensate for the underling disk technologies. So, by using a RamSan620 you could get most of the hardware improvements from the Exadata2 without the additional costs! I would still like to see the affects of using the Exadata parallel query engine on top of the RamSan620. However, given that the RamSan10/20 has 50 microsecond access time there would still be some benefit to having an internal PCIe based Flash cache on top of 250 microsecond external flash.

Well, have a great day!

Mike
