Ares has five internal 3.5 inch hard disk drives.
Ares boots up from a 36.4 GB SCSI hard disk, and this disk has two primary partitions and one logical:
Disk /dev/sda: 36.4 GB, 36420075008 bytes 255 heads, 63 sectors/track, 4427 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 4244 34089898+ 83 Linux /dev/sda2 4245 4427 1469947+ 5 Extended /dev/sda5 4245 4427 1469916 82 Linux swap / Solaris
Partition 1 is the
Ares also has four IDE disks that form three RAID 5 sets. The partition table of each disk is:
Disk /dev/hde: 203.9 GB, 203928109056 bytes 255 heads, 63 sectors/track, 24792 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hde1 1 1703 13679316 fd Linux raid autodetect /dev/hde2 1704 7783 48837600 fd Linux raid autodetect /dev/hde3 7784 24792 136624792+ fd Linux raid autodetect
Note that although all four disks were originally 203.9 GB in size, one disk recently failed and needed to be replaced. It was replaced with a 250.0 GB drive which has the same partition table. There are three further 250.0 GB drives to be used as cold spares in case further drives fail.
