Spormann File Server (SP-FS)

The foundation of the Spormann Lab network resources is the Spormann File Server, or SP-FS

SP-FS is a Dell PowerEdge 2850, with 3 GB RAM and two 2.8 GHz Pentium-4 processors.

SP-FS pictureIt serves the following functions for the lab:

  1. File Server for lab-member personal storage (25 GB User Shares)
  2. Filemaker Server hosting strain databases in the long-term strain collection.
  3. MySQL Server hosting a Geneious database for easy sharing of genetic data and annotations.
  4. Virtual Machine Server of VMWare-based virtual machines. This task is fairly computing intensive, and has been migrated to the Mac-based computing server. The capability still exists if needed.
  5. Intranet Server (Phased Out). These web-collaboration roles have been migrated to Stanford's servers via this website.

SP-FS operates with Windows Server 2003 installed on a SCSI-based RAID5 array with a total effective capacity of 900 GB (4 x 300 GB, with parity). In addition, a sophisticated backup protocol runs daily/weekly to backup Lab Members data to a second RAID5 array of a Network Attached Storage (NAS) device in a separate location. This second array performs a third backup to an attached external hard drive. In order for catastrophic data loss to occur, two of the industry-standard SCSI drives on SP-FS will have to fail at the same time as two drives on the separate NAS and its backup. That is a total of five nearly-simultaneous drive failures for full data loss to occur. The purpose of this redundancy is to ensure that hard-earned lab member data is never lost, but comes at the cost of research capital, maintenance hours, and energy (performing those backups requires many hours of CPU time per week). Please take advantage of it by following the instructions in the links above.
