New components and updates from previous versions of the 4.
solution
This section provides information on the updates in this version of the NSS-HA solution when compared
to the previous version
(4)
. The current version includes several major changes and updates to various
components of the solution.
4.1. Storage density
In previous versions of NSS-HA, each storage enclosure was equipped with 12 3.5” 2TB NL-SAS disk
drives. The larger capacity 3TB disk drives are a new component in the current version. The storage
arrays in the solution, Dell PowerVault MD3200 and PowerVault MD1200 expansion arrays are the same
as in the previous version of the solution but with updated firmware. The higher capacity 3TB disks now
allow higher storage densities in the same rack space. Table 2 provides information on new capacity
configurations possible with the 3TB drives. This table is not a complete list of options; intermediate
capacities are available as well.
