24 Sun StorEdge 3000 Family Best Practices Manual • March 2007
■
Use dual pathing for each LUN and use Sun StorEdge Traffic Manager software to
provide load balancing across controller ports for increased performance.
■
The maximum number of LUNs when using point-to-point protocol is 128 for
single-path configurations and 64 for dual-path configurations.
■
Power-up the equipment in the following order:
a. Expansion units
b. RAID array
c. Host computers
■
Install Sun SAN Foundation software along with the latest patches and firmware.
Note that the Solaris 10 operating system includes equivalent functionality, so no
additional SAN Foundation software is necessary.
■
Install current Sun Storage Automated Diagnostic Environment (StorADE)
software.
■
Connect the Ethernet management ports to a private Ethernet network (Sun
Alert# 26464).
■
For security reasons, use the RAID firmware to assign a password to the RAID
controller. Changing the firmware’s Network Protocol Support settings can
provide further security by disabling the ability to remotely connect to the array
using individual protocols such as HTTP, HTTPS, telnet, FTP, and SSH.

■
After completing the configuration of a Sun StorEdge 3510 FC array or Sun
StorEdge 3511 SATA array, the configuration should be saved using the firmware
“Save nvram to disks” menu option or the Sun StorEdge Configuration Service
Console's
save configuration
utility.
■
Partial or complete loss of data can be caused by the presence of media read error
conditions on physical disk drives. The impact varies, depending on RAID level.
To minimize availability issues caused by possible media read error conditions,
enable Media Scan frequently (at least once every thirty days) on logical drives.
