[QUOTE="sydras, post: 2022787, member: 4933"] Thank you for your reply. W.r.t. points 2 and 3, Our product build process does not involve any compilation but rather assembly of application packages delivered to us from various geographic locations to create an integrated product. I'm not a 100% sure on this though as we are yet to receive transition of the product build activity. Our specific build process seems to be I/O intensive as I do not see a lot of CPU usage during the build process. 1-2 processors seem to work at full load while the remaining 30 processors seem to be relatively idle. W.r.t. point 4, we require a SAN volume to be attached to our product build server mainly to store daily builds, each of which is around 30G. The 500GB or so filesystem on our 600GB server disk (two 600GB disks in RAID 1) would run out of space after a few days as we produced a 30GB build each day. So, we attach say a 4TB SAN slice (or SAN volume as it is called) from the 60TB SAN that we have to our blade server as a physical device (/dev/sdX). We then deploy an ext3 ot ext4 filesystem on this device. W.r.t. high availability, we are currently using a single SAN switch through which all our physical servers access our SAN. We'd already had a SAN switch failure about a year ago which led to a complete stop of activities for my group until the faulty SAN switch was replaced. We've already procured a 2nd SAN switch from HP for multipathing our server access to the SAN but HP folks for some reason seem to be unable to figure out how to connect our SAN to the 2nd SAN switch :). I am not familiar with OpenStack and Hybrid RAID. I will read up on it and see whether we can use it for our specific activity. [/QUOTE]
