Schuster Lab Server Information

The Schuster Lab has three main file servers: linne, s2, and s3

linne

• Apple Xserve G5
• Two 2.3 GHz PowerPC G5 processors
• 6GB RAM
• MacOS X 10.4
• Xserve RAID
  • xraid_HD1: 2.7TB
    • Seven 500GB FC disks in a RAID 5 set
  • xraid_HD2: 2.7TB
    • Seven 500GB FC disks in a RAID 5 set

linne is a file server as well as the head node for the linne cluster (31 nodes running MacOS X 10.4, 5 nodes running Red Hat Enterprise Linux 4.5).

s2

• Dell PowerEdge 1950
• Two quad-core 2.0 GHz Xeon E5405 processors (8 cores total)
• 8GB RAM
• Solaris 10
• PERC 6/E Adapter, 512MB
• Three Dell PowerVault MD1000 Storage Enclosures
  • md1k-6: 12TB
    • Fourteen 1TB SATA disks in a RAID 5 set and one 1TB SATA disk hot spare
    • zpool md1k-6
  • md1k-5: 12TB
    • Fourteen 1TB SATA disks in a RAID 5 set and one 1TB SATA disk hot spare
    • zpool md1k-5
  • md1k-4: 12 TB
    • Fourteen 1TB SATA disks in a RAID 5 set and one 1TB SATA disk hot spare
    • zpool md1k-4

s2 is a file server that is connected to both the persephone (s2.persephone.bx.psu.edu) and linne (s2.linne.bx.psu.edu) network switches. Each Dell PowerVault MD1000 uses 14 drives in a RAID 5 set with 1 drive as a hot spare to present a single virtual drive to the operating system. Each virtual drive is used to create a ZFS zpool. Each zpool contains two zfs file systems.

• md1k-6
  • md1k-6/archive
    • used for archiving sequencing runs
    • exported read-only
    • gzip compression
  • md1k-6/data
    • used for arbitrary data
    • exported read-write
    • lzjb compression
• md1k-5
  • md1k-5/archive
  • md1k-5/data
• md1k-4
  • md1k-4/archive
  • md1k-4/data

Each zpool is auto-scrubbed once a week. A cron job runs the /root/monitor/check_server_status shell script once an hour and emails and errors to email addresses in the /root/monitor/error_log_recipients.txt file.

s3

• Dell PowerEdge 1950
• Two quad-core 2.0 GHz Xeon E5405 processors (8 cores total)

• Three Dell PowerVault MD1000 Storage Enclosures
  • md1k-3: 8.7TB
    • Fourteen 750GB SATA disks in a RAID 5 set and one 750GB SATA disk hot spare
    • zpool md1k-3
  • md1k-2: 8.7TB
    • Fourteen 750GB SATA disks in a RAID 5 set and one 750GB SATA disk hot spare
    • zpool md1k-2
  • md1k-1: 8.7TB
    • Fourteen 750GB SATA disks in a RAID 5 set and one 750GB SATA disk hot spare
    • zpool md1k-1
