Your enclosure can be one of up to fourenclosures daisy-chained to a single port on the controller card in your host server. The enclosure can also be connected in a redundant path mode withtwo connections to a single host server.• In a split-mode configuration, your enclosure is connected to two separate controller cards. The controller cards may reside in the same server or in twodifferent servers. The enclosure bus is logically split in half where the first half of the enclosure is managed by one controller and the second half of theenclosure is managed by the second controller .The table below lists the drives that are controlled by each enclosure management module (EMM) in a split-mode configuration.NOTE: Split-mode configurations do not support daisy-chaining of enclosures and redundant paths.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 turningon the enclosure has no effect on the enclosure configuration until the enclosure is rebooted.For examples of supported cable configurations, see “Cabling the Enclosures to the Host Server(s)” below.For more information about cabling your enclsoure, see theDell™ PowerVault™ MD1200 and MD1220 Storage Enclosures Hardware Owner’s Manual atssuuppppoorrtt..ddeellll..ccoomm//mmaannuuaallss.EEnncclloossuurree EEMMMM 00 EEMMMM 11Dell PowerVault MD1200 Drives 6 to 11 Drives 0 to 5Dell PowerVault MD1220 Drives 12 to 23 Drives 0 to 111.
