Sun Microsystems StorEdge 3510 User Manual

Chapter 4 Connecting Your Fibre Channel Array 4-25
4.10.1 Scaling a Sun StorEdge Fibre Channel Array Into
a High Capacity Configuration
Note – High capacity Sun StorEdge 3510 and 3511 FC array configurations are
supported with certain limitations. For example, only the sequential cache
optimization mode can be used. Other important limitations may exist. A Sun
StorEdge 3510 FC array with more than two expansion units is a high capacity
configuration. A Sun StorEdge 3511 FC array with one expansion unit is a high
capacity configuration.
Sun StorEdge 3510 FC arrays typically allow the connection of up to two expansion
units to support a maximum of 36 disks. However, you can create larger
configurations that support as many as eight expansion units and up to 108 disks if
you use the guidelines in this section. You can also create larger configurations of
Sun StorEdge 3511 FC arrays that support from one to five expansion units and up to
72 disks.
Carefully consider the following limitations of special high-capacity configurations.
Using multiple Sun StorEdge Fibre Channel arrays connected to the same SAN
normally provides significantly better performance than one high-capacity
configuration.
■ Random optimization should not be used with high-capacity configurations, and
it should never be used with the Sun StorEdge 3511 FC array. Use the default
sequential optimization instead. Random cache optimization greatly reduces the
maximum number of supported disks.
■ Only cabling configurations described in the Sun StorEdge 3000 Family Best
Practices Manual are supported when configuring a high-capacity Sun StorEdge
3510 or 3511 FC array.
■ Maximize the size of each logical drive (up to 1908 Gbyte) before creating another
logical drive in order to allow for maximum storage capacity.
■ Sun StorEdge 3510 FC arrays can only be connected with Sun StorEdge 3510 FC
expansion units. Similarly, Sun StorEdge 3511 FC arrays can only be connected
with Sun StorEdge 3511 FC expansion units. The two models of arrays and
expansion units cannot be mixed.
Refer to the Sun StorEdge 3000 Family Best Practices Manual for additional cabling
diagrams.
Note – Large configurations may require the use of one or more 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.
