Ultimately, it depends upon your job flow and how much data you have. FWIW we're currently using a Sun equivalent of the C2100s w/8 of the 12 drive slots filled. You need a *LOT* of iops to make it worth while. [From what I've seen, even people who think they have a lot of iops generally have other problems with their code/tuning that are causing the iops. So even if you think you have a lot, you may not.] > I'm curious if any other's are running Dell PowerEdge servers with Hadoop. > > We've also been kicking the idea around of going with blade servers (Dell > and/or HP). If you are thinking traditional blade where storage is comes mainly from NAS or SAN, you are going to be very, very unhappy unless your data set is very, very tiny. Check out the PoweredBy page on the wiki. Quite a few folks list their gear. FWIW, we're currently evaluating HP SLs and should be getting some Dell C6100s in soon, assuming Dell can deliver the eval unit on time.
