- Dual redundant hot-swappable power supplies.
Disks, RAID and LVM
Two 500GB drives were installed in 2009, and are on top in slots 1 and 2. One of these died in 2012 and was replaced. They are both connected via the onboard SATA controllers (blue cables). Each is partitioned as follows:
255 heads, 63 sectors/track, 19452 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 * 1 2432 19535008+ fd Linux raid autodetect /dev/sdb2 2433 19452 136713150 fd Linux raid autodetect
sdb1 and sdc1 are in a software raid1 partitioned with ext3 and contain slash. sdb2 and sdc2 are in another software raid1 on top of which there is LVM. The volume group is called raid1 and contains logical volumes for /tmp(5GB), /var(5GB) and swap(8GB). var and tmp are ext3. The four 250GB drives are on the bottom in slots 3, 4, 5 and 6. They are connected via the hardware RAID controller (red cables). These are combined into a RAID5 device (sda), and can be managed using afacli. The entirety of this device is in LVM in a volume group called raid5. The main logical volume is /home which is partitioned with ext3.
Spoon has 2 network cards. The primary gigabit card is eth0, which we use to connect to TCD. The second card (100 megabit) is eth1, and provides a direct crossover link to Cube that admins can use independent of the College network.
Using IPMI there is some amount of monitoring possible for Spoon.
