Hardware Expansion and Upgrades
The Spectra T950V library is designed to expand to meet changing storage
requirements, as well as to achieve storage consolidation goals. These
expansion and upgrade options can be purchased through a sales
representative (see Contacting Spectra Logic on page 7).
The following table describes the types of hardware expansion and
upgrades that are available.

Description
If all of the currently installed DBAs in the library are fully populated with
drives and your library includes shelves in the back of a main or drive frame,
you can replace shelves with a DBA.
Note: Replacing shelves with a DBA reduces the storage capacity of your
library.
If all of the currently installed chambers in the library are fully populated with
TeraPack magazines and your library includes more than one Drive Bay
Assembly (DBA), you can replace a DBA with shelves .
Note: Replacing a DBA with shelves can reduce data throughput.
Each Drive Bay Assembly (DBA) holds up to four drives. If a DBA is not full,
additional drives can be installed to increase data throughput.
Important: Do not attempt to install drives purchased from other vendors in
the library. The drives used in the library are specifically configured for use in
the library and must be purchased from Spectra Logic.
The storage capacity or performance of the library can be increased by adding
media or drive expansion frames, respectively.
See Drive and Media Frames on page 55 for information about the number and
types of expansion frames that can be added to the library.
The library requires a minimum of one 5/12 VDC power supply module per
populated DBA. It also requires a minimum of one 24 VDC robotics power
supply module in the main frame. Optionally, you can purchase an additional
supply per frame, which in combination with the dual AC power inputs,
provides redundancy and failover protection. The power supply modules
needed for the power redundancy configuration are an option you can
purchase separately or when you order the library.
A RIM2 can be used to provide the robotic control path for a partition. One
RIM2 can support up to 16 partitions.
Two or more RIM2s are required if you want to use the BlueScale controller
failover feature for enhanced availability.
You can use a USB device for saving backups of the library configuration and
MLM database, when you are updating the library's BlueScale software, or as a
troubleshooting tool for use as instructed by Spectra Logic Technical Support.
USB devices are available for purchase from Spectra Logic for a nominal charge.
Note: The library only recognizes FAT‐formatted, not NTFS‐formatted, USB
devices.
