Information

Apocalypse is a multipathed SAS storage array. This means that each drive has two SAS paths via two separate backplane modules. It also means that Apocalypse requires dual-ported SAS drives in order to take advantage of the redundant paths. There are a total of four SAS connectors on the back. The bottom two are redundant connections to the front SAS backplane and the top two are redundant connections to the rear SAS backplane.

Population

The Apocalypse array contains the following disk groups:

• 11 2-terabyte 7.2k rpm Seagate ST2000NM0023 drives (forms the second Apocalypse vdev)

• 11 1-terabyte 7.2k rpm Seagate ST1000NM0001 drives (forms the first Apocalypse vdev)

• 4 6-terabyte 7.2k rpm HGST HUS726060AL4210 drives

• 6 900-gigabyte 10k rpm Western Digital WD9001HKHG-02VUC drives

  3 200-gigabyte HGST HUSMM1620ASS200 solid state drives (currently unused)
