The current setup in codfw for labstore offline backup servers is:
- Labstore2001 at rack B1 is idle and connected to labstore-array[0,1,2,3]-codfw via H800. The attached storage amounts to 48 disks.
- Labstore2002 at rack B1 is idle, has H800 card available, but no connected storage
- We have two additional shelves available with 12 disks each(?) - labstore-array4-codfw, and labstore-sparearray2001-codfw, both in rack B1.
- For completeness, Labstore2003 and labstore2004 are at rack B8 and actively used as offline storage for NFS shares served from labstore1004 and 1005 (secondary cluster). These two servers have no attached storage, and have ~10.8T of internal storage each post RAID 10.
I would like to split up the external shelves labstore-array[0-4]-codfw between labstore2001 and 2002. We could connect 2 shelves to each and have two spares, or connect 3 shelves to one and 2 to the other, and have 1 spare shelf, to maximize storage available for backups, while also having a spare. All the storage can be set up with RAID 10
@Papaul Let me know if you have any questions or concerns! Thank you.
