Solid-state drive caching features

This information describes the solid-state drive (SSD) caching for the IBM XIV
Storage System.
SSDs, also known as flash drives, are storage devices that use nonvolatile solid-state
memory to reduce the latency and time to access the stored data. IBM offers an
SSD caching option, which uses SSDs for caching across all volumes. SSD caching
improves application performance by dynamically and adaptively caching the most
frequently accessed data on SSDs.
This feature includes a 400, 480, or 800 GB SSD in each data and interface module,
for up to 12.0 TB of management-free SSD caching.
The following table lists the feature available for each XIV model.
Note: Model 281x-314 includes 800 GB SSDs as standard features in each data and
interface module used in the system, so there are no SSD caching feature codes
associated with model 281x-314.

Radio frequency identification device feature

IBM offers an optional radio frequency identification device (feature code 0203) for
the XIV system.
If you use frequency identification device (RFID) technology to track equipment in
your data centers, you can order the RFID option (feature code 0203) to attach an
RFID tag on an XIV system. This RFID is designed to meet the performance and
