IBM TotalStorage DS4300 Fibre Channel Storage Subsystem: Installation, User's, and Maintenance Guide
Table 10. Support for new storage expansion enclosures within a DS4300 drive
loop (continued)
Notes:
1. The EXP100 and EXP710 operate at 2 Gbps FC speed only. Because the EXP810
operates at 2 Gbps and 4 Gbps FC speed, its enclosure speed must be set at 2 Gbps
before connecting to the DS4300 drive loop. Similarly, the EXP700 enclosure speed
switch must be set at 2 Gbps before connecting to the DS4300 drive loop.
2. Requires DS4300 controller firmware version 5.3x.xx.xx or 6.12.xx.xx.
3. The EXP100 requires DS4300 controller firmware version 5.41.xx.xx or higher.
Controller firmware version 6.12.xx.xx is required for intermixing EXP100, EXP700, and
EXP710 storage enclosures behind a DS4300 Storage Subsystem. It is recommended
that you use the latest general released firmware version 6.19.xx.xx if you do not have
the EXP700 storage expansion enclosures in the DS4300 drive loop.
4. The EXP710 requires DS4300 controller firmware version 6.12.xx.xx or higher. It is
recommended that you use the latest general released firmware version 6.19.xx.xx if
you do not have the EXP700 storage expansion enclosures in the DS4300 drive loop.
5. The EXP810 requires DS4300 controller firmware version 6.19.xx.xx or higher.
6. The FC/SATA intermix premium feature is required if there is a mix of FC and SATA
drives in the DS4300 Storage Subsystem.
7. The EXP700 requires the purchase of the DS4000 EXP700 Models 1RU/1RX
Switched-ESM Option Upgrade Kit if it is to be attached to EXP810s.
8. The EXP810 speed switch must be set to 2 Gbps.
