There are restrictions for sharing EMC
Symmetrix and Symmetrix DMX systems between a host and a Lenovo Storage V7000 system.
An EMC Symmetrix
or Symmetrix DMX system can be shared
between a host and a
Lenovo Storage V7000 under
the following conditions:
- When possible, avoid
sharing target ports between
the Lenovo Storage V7000 system
and other hosts. If this cannot be avoided, you must regularly check
the combined I/O workload that is generated by the Lenovo Storage V7000 system
and the other hosts. The performance of either the Lenovo Storage V7000 system
or the hosts is impacted if the workload exceeds the target port capabilities.
- A single host must not be connected to a Lenovo Storage V7000 and
an EMC Symmetrix or Symmetrix DMX because the multipathing drivers
(for example, subsystem device driver (SDD) and PowerPath) cannot
coexist.
- If the EMC Symmetrix or Symmetrix
DMX is configured
in such a way that other hosts cannot access the LUs that are managed
by the Lenovo Storage V7000 system,
other hosts can be directly connected to an EMC Symmetrix or Symmetrix
DMX system at the same time as a Lenovo Storage V7000 system.
