Expansion and Upgrades
The Spectra T950 library is designed to expand to meet a data center’s changing
storage requirements, as well as to achieve storage consolidation goals.

Make sure to plan ahead and take the library’s expansion capabilities into
consideration when you install and configure the library. Use its capabilities as
appropriate to implement long-term strategic storage plans.

Capacity
CoD is the library’s capacity-on-demand feature. You can purchase a library that suits
your current needs, and then purchase additional capacity later as required. This
reduces up-front costs, because you only pay for what you currently need. As more
capacity is required, add it in increments— purchase key codes to activate chambers in
the library and purchase additional TeraPack cases or RXT media packs to fill the
added chambers. These purchases can be made through a sales representative or
directly through the Spectra Logic Web site.

The CoD feature lets operators use all available physical chambers in that physical
library unit, also referred to as a frame; then, once all existing chambers are in use, add
another frame increase capacity. Additional frames can support either of these
configurations:
library unit, also referred to as a frame; then, once all existing chambers are in use, add
another frame increase capacity. Additional frames can support either of these
configurations:
• A combination of media and drives for greater throughput and capacity.
• Media-only for greater capacity.
Throughput and Connectivity
If the library frame’s Drive Bay Assemblies (DBAs) are not already filled to capacity
with drives, or if the library has room for additional Quad-Interface Processors (QIPs),
additional drives or QIPs can be easily installed to increase the library’s throughput.

The library’s QIPs can be switched out at any time to change the library’s connectivity
type. Additional QIPs also increase the library’s drive throughput.

Drives and QIPs are sled-mounted and install in under two minutes.
Power Supplies and USB Storage Devices
You may order and install additional power supplies for fail-over and redundancy.
You may elect to purchase additional USB storage devices that you can use when
upgrading the Spectra T950 library’s firmware package, or as a troubleshooting tool for
use as instructed by Technical Support.
