### HOME File System
The HOME filesystem is an HA cluster of two active-passive NFS servers. This filesystem contains users' home directories `/home/username`. Accessible capacity is 25 TB, shared among all users. Individual users are restricted by filesystem usage quotas, set to 25 GB per user. Should 25 GB prove insufficient, contact [support][d], the quota may be lifted upon request.
