Quantum DXi6900 User’s Guide 25
l Aggregated name spaces and file contents.
l Limited direct, active file access.
l Limited browsing, scanning, or stating.
l Limited metadata manipulation (including rename).
Usage diverging from these characteristics must be qualified to ensure acceptable behavior with respect to
functionality, performance, replication, and recovery.
Note:Using Backup Exec with GRT (Granular Recovery Technology) over CIFS is not recommended
usage. GRT requires frequently overwriting portions of and appending data to existing files, which is
inconsistent with the DXi usage scenarios. Instead, Quantum recommends using OST.
HDDs
The DXi6900 G1 and G2 Nodes support sixteen high capacity (900 GB for G1/1.2 TB for G2) hard disk
drives (HDDs) (see Figure 6 on the next page).
The Node hard drives are used for the operating system, system software, and indexes needed for data
deduplication, replication, and space reclamation.
The DXi6900 Array modules (RBODs) and Expansion modules (EBODs) each support twelve high capacity
(4 TB for DXi6900 G1/G2 and 8 TB for DXi6900-S) hard disk drives (see Figure 8 on page 27 and Figure 9
on page 27). The Array and Expansion module hard drives are used for data storage.
All hard disk drives are mounted and pre-assembled in drive carriers (see Figure 6 on the next page and
Figure 7 on the next page). All drives are hot swappable.
AdditionalInformation-DXi6900-S
l The DXi6900-S Node supports thirteen high capacity solid state drives (SDDs) (see SDDs on page
27).
l The DXi6900-S 8 TB Array module (RBOD) and Expansion module (EBOD) hard disk drives cannot
be used in DXi6900 G1/G2 systems.
