User Interface Change
In the previous RXT releases, the Tools menu item of the RXT Web interface was called
“Diagnostics” and the RXT Utilities screen was named the RXT Diagnostic screen.
Achieving Appropriate Transfer Speeds
The RXT150 is designed to achieve transfer rates of up to 110 MB/sec when configured
as RAID 0 in an optimal environment (that is, with an optimal data source and optimal
performance from the server connected to the RXT150).
Test have shown that speeds up to 110MB/sec are achievable in optimized
environments

Specifications
The RXT150 has been designed to achieve native transfer rates of 110MB/sec with
uncompressed data in optimal environments.
The RAID level on the RXT150, its network configuration, and the use of data
compression will affect the transfer rate of the drive.

Important Information
The information presented here represents the most up-to-date information that
Spectra Logic can provide you to supplement the product user guides and other
printed material.
Running on Solaris 9.0
To run RXT Firmware Version 1.1.0.63 on SUN Solaris 9.0, you must update to the
Solaris 9 Recommended Patch Cluster (177.3M), which is available at:
http://sunsolve.sun.com/pub-cgi/show.pl?target=patches/patch-access.
Ultra-320 SCSI Compatibility
RXT drives use Ultra-320 SCSI. To avoid problems, ensure that your HBA supports
Ultra-320 SCSI connectivity.
Compression Issues
Data is not compressed if you are using the following combination of products:
• BlueScale Encryption Professional Edition
•RXT
• NetVault and Backup Exec, which don’t accept variable block size
Time Changes
The RXT drive does not automatically adjust for Daylight Savings Time; it is up to the
user to manually change the time.
Logging Out of the RXT Web Interface
You can log out of the Web interface or switch users by clicking the User link at the
bottom of the Web interface.

Spectra RXT Firmware
Updates
Check Spectra Logic’s web site for the latest RXT firmware information, located at
www.spectralogic.com/firmware.
User Firmware vs. Auto Firmware
User Firmware
User Firmware is the firmware image that has been placed on the RXT media by a user
through the web interface (or front display interface). With RXT media loaded in a RXT
drive, a user can save the RXT drive’s operating firmware to a partition on the RXT
media. The user can then update the firmware in other RXT drives by loading that RXT
media into other drives and using the firmware upgrade function of the web interface
(or front display interface).
Auto Firmware
Auto Firmware automatically protects data from firmware mismatches that may prevent
the data from being read or written. As with any removable media, there is a risk over
time that the data format of the media will not match the data format of the drive. Auto
Firmware assists the user in preventing this from happening.
An Auto Firmware file is automatically written to RXT media when it is first written to
in a RXT drive. Following that, whenever RXT media is placed into a RXT drive, the
RXT drive checks the data format of the RXT media to make sure that the levels match.
In the event that the RXT drive’s operating firmware is a lower format version than the
RXT media’s Auto Firmware, the user is notified and asked to update the RXT drive to
the latest level.

the RAID array is successfully rebuilt after the operation finishes.
