A Direct-attached storage and a good server for a Swift cloud

asked 2012-11-09 03:41:37 -0600

HI all,

We have a small swift cloud that has 5 zones. These zones have Dell Powedge R210II servers Now, we are planning to increase the storage capacity of our cloud. Our doubt is: how would swift work if we add a Direct Attach Storage (DAS) to one of the servers. Is this ok or would this  increase the latency too much.

 If a DAS is not good, how would swift behave if we a 4 disk server as HP ProLiant DL320 G6 Server (http://h10010.www1.hp.com/wwpc/us/en/sm/WF06a/15351-15351-3328412-241644-241475-3929672.html?dnr=1)

             Thank you very much,

In general, there's nothing wrong with using a DAS for storage, assuming it has a fast enough interface. You'll need to make sure you have enough CPU and networking for the new number of drives. I think what we have documented for reference is a 24 drive machine with 8 cores and a single GigE network interface, so something close to those ratios, should be good (informed by your current CPU and network usage).
