-The HPCC has invested in a new solution for our Home Directories file server. The TrueNAS/ZFS solution selected is described here [[cluster:186|Home Dir Server]]. We will implement with very large user quotas. The storage is 190 TB usable with inline compression (475 TB effective usable if compression ratio achieved is 2.5x).  Other features include; unlimited snapshots point in time restores), read cache SSD, write cache SSD, self-healing (checksums on reads and writes and per schedule), RAIDZ2 protection, high availability (dual controllers). We will not implement de-duplication. Maybe add replication in the future. This will take along time to deploy. \\

-The HPCC has also invested in more GPU and CPU compute capacity. At the time of this writing, 12 nodes are crossing Iowa from CA headed our way. A total for 48 gpus (model rtx2080s and 384 GB memory), 24 cpus (228 physical cores and 1,152 GB memory). Details of the selection process can be found here [[cluster:181|2019 GPU Models]]\\
