BAS Architecture
BAS XFS Front Server
XFS is scalable high performance journaling file system which is very proficient at handling large files.
All volumes from the storage array and its JBODs are visible in BAS XFS Front Server and each is formatted into XFS filesystem. Each server has 9 or more XFS volumes, approximately 60TB each (different options are possible, for instance a single XFS file system with combining all volumes with LVM).
BAS 715TB / 536TB
BAS 715TB consists of 4 modules and BAS 536TB consists of 3 single-controller modules.
Each module consists of 3 x RAID 60 blocks.
Each RAID 60 blocks consists of two striped RAID6 groups.

Black Hole
Black Hole is a secure installation site where data recording components (such as HDDs, SSDs, etc.) go in and do not come out as they have to be destroyed on site. Normally such customers require purchasing spare disk drives on additional expense to change the faulty ones, but in BAS case Black Hole customers are entitled for data recording components warranty replacement without the need to return the faulty components to NOVATTE.
