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 1).
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 3 and Figure 4). 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 1 and Figure 2). All drives are hot swappable.
Additional Information - DXi6900-S
- The DXi6900-S Node supports thirteen high capacity solid state drives (SDDs) (see SDDs).
- The DXi6900-S 8 TB Array module (RBOD) and Expansion module (EBOD) hard disk drives cannot be used in DXi6900 G1/G2 systems.
