The Dell PowerEdge R510 hosts are used for the es1001-es1010 hosts in eqiad.

[edit] Hardware stats

12 disks hardware raid card

[edit] Performance statistics

These tests done with the disks configured:

• raid 10
• 256k stripe
• no read ahead
• writeback cache

Tests performed with sysbench 0.4.10-1build1, standard debian package (obtained by 'aptitude install sysbench')
