ML350 & Windows Clustering

Hello,

Can anyone explain why ML350s are not supported for clustering under fibre based storage solutions?

Re: ML350 & Windows Clustering

The ML350s are supproted with SCSI clusters with the MSA500 storage box (see ftp://ftp.compaq.com/pub/solutions/enterprise/ha/microsoft/win2003/2003EE_SACS.pdf). This is an entry level cluster.

The ML350s are targeted at a different market - they do not support Hot Plug PCI or redundant system fans. It is not really a technical issue, as they would most likely work just fine.

Another thing is that the rack version is 5U, which takes a lot of rack space when compared to something like the DL380, which is only 3U. This is important because in a cluster you have very little internal storage, as it all resides on the external shared storage. So customers tend to focus on the DL line of ProLiant serevrs since they take up less space.

Thanks,

Re: ML350 & Windows Clustering

Thanks Doug. The hot plug issue might be the reason. The size issue do not sink in with me because ML570s widely used for clustering.

Once again thank you very much for your opinion.

Re: ML350 & Windows Clustering

The size isuue is only one factor. HP focuses their cluster certification resources on the DL and Blade lines first (because of the size issue), but also certifies selected ML servers as well. The ML570 is a more robust server (from an HA perspective) than the ML 350 - it has Hot Plug PCI as well as redundant fan options. So this one makes a little more sense because it fits in better with an overall HA strategy.

Thanks,
