Dell PowerVault MD1200 Manuale tecnico
• In a split-mode configuration the enclosure is connected to either two host controllers or two ports on
a single host controller. The enclosure can be connected to two different host servers in a split mode
configuration. Each server sees the enclosure as an independent device with half of the total enclosure
slot capacity. Table 10 lists the drives that are controlled by each enclosure management module
(EMM) in a split-mode configuration. See Figure 11 for a cabling diagram of a split-mode configuration.
The operating mode is selected using the enclosure mode switch on the front panel of the enclosure.
NOTE: The enclosure mode switch must be set to either unified mode or split mode before the
enclosure is turned on. Changing the configuration mode after turning on the enclosure has no effect on
the enclosure configuration until the enclosure is rebooted.
NOTE: Clustering is not supported on PowerVault™ MD1200 and PowerVault™ M1220 enclosures.
