OACISS has multiple network attached storage systems for user operations. In addition, certain systems may have additional local disks, most often for storage of local images related to container infrastructure like Docker or Shifter.
Network attached storage operates over the 172.17 Ethernet, which is increasingly being upgraded to 100GbE performance.
Main storage: /home/users
All systems in the CC utilize the main home directory NAS server on Mnemosyne. This is a primary storage engine with 12 15TB sas-3 SSDs in a raidz2 redundant storage array providing 128TB of disk in one volume.
Single-thread IO tests yield ~1.8GBps sequential read and ~10K IOPS 4K random r/w.
Package tree: /packages
Package trees for RH7, RH8 and ppc64le are stored on 15TB SAS-12G SSDs in RAID-1.
As packages are subject to almost exclusively read access, they are mounted synchronously.
High performance storage: /gpfs/gpfs0
OACISS has deployed an IBM GS4S high-performance file server utilizing the Spectrum Scale storage engine. The ESS server cluster has 96 4TB SSDs providing a total of 250TB of storage. The ESS cluster is linked to the private storage network with 200Gbps of Ethernet bandwidth.
The underlying high-performance Spectrum Scale filesystem driver is able to deliver up to approximately 3GBps of sequential IO per thread.
BeeGFS storage
The majority of nodes have a high performance BeeGFS filesystem available.
The data storage lives on a dedicated host, Alexandria, with 15 x 15TB NVME drives arranged in a 180TB raidz2 pool.
Upstairs storage
Upstairs storage is a 28TB SSD storage pool living on Sphinx, serving Silicon and the ARM hardware cluster (jetsons, xaviers, orins and OD1K).
This storage, and its package tree, are entirely separate from main storage.
