SAS cable lengths
The StoreOnce implementation uses Managed Cables, making it easier to identify faults. The
StoreOnce software verifies that the correct length SAS cables are being used. Mini-SAS HD
connectors are used throughout.
SAS cables should 'click' and lock into position when correctly inserted. Three cable lengths are
available. The maximum supported cable length is 2.0 m.
Table 7 Supported SAS cables
Description
0.5 m Mini-HD SAS to Mini-HD SAS cable
1.0 m Mini-HD SAS to Mini-HD SAS cable
2.0 m Mini-HD SAS to Mini-HD SAS cable
NOTE:
To facilitate future expansion, HPE recommends using 2.0 m SAS cables to connect
from the server to Drawer 2 of the disk enclosure. For this reason, the base system of one server
and one disk enclosure is supplied with two 0.5 m cables and two 2.0 m cables.
