eddyc Posted July 18, 2013 Posted July 18, 2013 Hi all, Over the summer we are replacing our CCTV server (can't really put it on to the virtual environment due to the running demands and storage demands of the machine) so we have just bought a server. We have 2x 500GB SATA drives mirrored for the OS and for the data we have 10x SAS 4TB 6gbps drives. What RAID configuration would you put the data drives in? We need redundancy so we do not want a RAID0 but do not want to lose recordings if a drive fails - so what would you do? Thanks, eddyc
CyberNerd Posted July 18, 2013 Posted July 18, 2013 I'd do a mirror with a hot spare - you'd be able to record for months! 1
pantscat Posted July 18, 2013 Posted July 18, 2013 What does the storage controller support? RAID-6 would probably be a good option, it could withstand two failed drives and keep going... 1
cpjitservices Posted July 18, 2013 Posted July 18, 2013 RAID10. RAID 10 In RAID 10, often referred to as RAID 1+0 (mirroring and striping), data is written in stripes across primary disks that have been mirrored to the secondary disks 1
tmcd35 Posted July 18, 2013 Posted July 18, 2013 Given the number of drives, I'd go for RAID-10 with a couple of hot spares. 16Tb, speed, redundancy and fail over. 1
eddyc Posted July 18, 2013 Author Posted July 18, 2013 The server is a DELL PowerEdge R720XD with a PERC H710p RAID Controller 1gb cache
tmcd35 Posted July 18, 2013 Posted July 18, 2013 With RAID 6 you'd get 32TB useable... But slower write speeds. And since it's for CCTV video, I'd go less space more speed on this one. 1
cpjitservices Posted July 18, 2013 Posted July 18, 2013 Agreed. But slower write speeds. And since it's for CCTV video, I'd go less space more speed on this one.
