Sun StorEdge 3511 SATA Array
High-Capacity Configurations
Sun StorEdge 3511 SATA arrays allow the connection of up to five expansion units to
support a maximum of 72 disks. You can create large configurations beyond 12 disks
if you use the guidelines in this section.
Note – Do not use a Sun StorEdge 3511 SATA array to store single instances of data.
It is more suitable for use in configurations where the array has a backup or archival
role.
See “Sun StorEdge 3510 FC Array High-Capacity Configurations” on page 43 for
information about adding more than two expansion units to a Sun StorEdge 3510 FC
array.
The use of a full-fabric SAN configuration is highly recommended for host
connections, as shown in
“Full-Duplex SAN Configurations” on page 35 .
Refer to the Sun StorEdge 3000 Family FRU Installation Guide for information about
supported disk drives, cables, SFPs, and other user-replaceable items.
Note – The following high-capacity configurations illustrate cabling techniques for
drive ports. They must be combined with a standard configuration described in this
document, such as shown in
“Redundant Point-to-Point SAN Configurations” on
page 39 . They must also be used with the network applications appropriate to the
array, as summarized in Chapter 1 and described in more detail in the Installation,
Operation, and Service Manual for your array.
For additional late-breaking technical and configuration details about SATA disk
technology and the Sun StorEdge 3511 SATA array, be sure to check the release notes
for your array.
