- 1U Rackmount server with 4 x 1000GB 3.5" SATA drives and one 2.5" 32GB Boot SSD
- Debian 8
- Connected to Equipment/Cisco1 via port 37 & 38 in a 2 port LACP channel bond.
- Runs Samba (workgroup 'LHS') and has 2 shares:
- space, which is read/write to everyone on the local network
- managed which contains useful things that are of interest to hackspace members.
- shares /home over nfs, currently used by lamarr at least.
Motherboard and Memory
Lattner has 32GB of ECC DRAM and is powered by a SuperMicro X7DBU motherboard. Possible management via IPMI is available via an off-board card that is currently NOT installed.
Disk Configuration
- 4 1TB drives connected directly to the motherboard SATA ports.
- System is using ZFS in a RAIDZ2 (Double-Parity) RAID providing 1800GiB of usable storage.
- zpool was created using device-aware /dev/disk/by-id rather than generic /dev/sda,sdb,sdc,sdd enumeration to help facilitate disk replacements when a drive goes down:
- HOW? By labeling the outside of the drive-tray with the disk serial number, we can easily reconcile the serial number of a failed/failing drive with one that is in the array.
- Boot drive is simply an SSD.
