See “Sun StorEdge 3511 SATA Array High-Capacity Configurations” on page 57 for
information about adding expansion units to a Sun StorEdge 3511 SATA array.
These configurations work best when you select the highest-capacity disk available
without exceeding maximum limits set by the firmware. Refer to the
Sun StorEdge
3000 Family FRU Installation Guide for information about supported disk drives,
cables, SFPs, and other user-replaceable items.
The use of a full-fabric SAN configuration is highly recommended for host
connections, as shown in
“Full-Duplex SAN Configurations” on page 35 .”
Note – The following high-capacity configurations illustrate cabling techniques for
drive ports. They must be combined with a standard configuration shown in this
document, such as shown in
“Redundant Point-to-Point SAN Configurations” on
page 39 .
Limitations
■
Maximize the size of each logical drive before creating another logical drive.
Otherwise the maximum number of 32 logical drives might limit future
expansion.
■
Limiting the maximum number of expansion units on a Sun StorEdge 3510 FC
array to 7 provides greater configuration flexibility. Doing so enables the use of
up to 96 disks.
■
If you stack a tabletop array and expansion units on top of each other, you can
stack up to five physical units. Do not stack more than five physical units.
■
Many of these configurations require the use of optional extended-length cables,
part number X9732A. Other items may also be required. Refer to the
Sun StorEdge
3000 Family FRU Installation Guide for information about supported cables, SFPs,
and other user-replaceable items.
