Sun Storedge 3900 And 6900 Series Switchless Systems - Sun Microsystems StorEdge 3900 Series Reference And Service Manual

1.1.5 Sun StorEdge 3900 and 6900 Series Switchless
Systems
Sun StorEdge 3900 and 6900 series systems are supported without built-in front-end
switches. The Sun StorEdge 3900SL, 6910SL, and 6960SL series systems (switchless
configurations) are for customers who want to install these systems into existing
SAN environments that are built using third-party (non-Sun) switches. When
purchasing a switchless configuration, the following items apply:
Sun provides prime input power cords (two each) for mounting a pair of third-
party switches in the front end of a Sun StorEdge 3900 or 6900 cabinet.
For the Sun StorEdge 3900SL system, Sun provides FC cable connectivity for up to
nine Sun StorEdge T3+ arrays.
For the Sun StorEdge 6910SL system, Sun provides two FC cables to connect to
two virtualization engines.
For the Sun StorEdge 6969SL system, Sun provides four FC cables to connect to
four virtualization engines.
With Sun StorEdge 3900 and 6900 series switchless systems, customers are
responsible for providing:
All host FC cable connections
An Ethernet cable connection between the third-party switches and the local SAN
maintenance console. This is used to monitor and perform diagnostic reporting.
(The customer-supplied switches are not part of, or monitored, by the internal
service processor of the Sun StorEdge 3900 or 6900 series switchless system.)
Note – A customer-supplied switch installed in a Sun StorEdge 3900SL or 6900SL
system cannot be connected to the internal LAN of the system. The customer-
supplied switch must be managed from an outside Ethernet connection.
Brocade and McData switches are "operable" with the switchless Sun StorEdge 3900
and 6900 series systems under the SAN 4.0 rules. Sun support for the Brocade
switches (2400, 2800, and 3800) is dependent upon Sun Professional Services
implementation and an Enterprise Services support services agreement.
The McData switches are not currently supported by Enterprise Services unless they
are part of a Sun StorEdge 9900 configuration. The switches in the SAN must be
homogeneous (all SUN or all Brocade or all McData). It is Sun's intent to support
heterogeneous interoperability between switches at a later date.
