1 Refer to Table 1 to determine how many physical drives can be included in one logical drive.
Non-Redundant DAS Tips and Techniques
■
A Sun StorEdge Fibre Channel array with a single controller can be configured to
support up to four host connections (Sun StorEdge 3510 FC array) or 6 host
connections (Sun StorEdge 3511 SATA array). These connections can be used in
pairs, individually, or in any combination of both.
■
You will need to add SFP modules to support more than two host connections to
the Sun StorEdge 3500 series array. Add:
■
One SFP module to support three connections
■
Two SFP modules to support four connections
