ItemNumber Name Description1 12 gbps SAS Host Ports (2) Allows you to connect host servers to thestorage array.2 7–segment display Displays status of the controller.3 1G Ethernet Management (MGMT) Port (1) Allows for out of band management ofstorage array.4 Reserved Ethernet Port (1) This is a reserved port.5 12 gbps SAS Host Ports (2) Allows you to connect host servers to thestorage array.6 SAS Expansion Ports (2) Allows you to connect the storage array tooptional PowerVault MD1200 seriesexpansion enclosures for additional storagecapacity.NOTE: Only one SAS OUT expansion port can be used at a time and the recommended expansionport is port 0.NOTE: Do not cable the reserved management port.Each PowerVault MD3400 and MD3420 storage array can be expanded to a maximum of 120 slots (or192, if enabled using Premium Feature activation) through a maximum of seven MD1200 series expansionenclosures.Cabling The Storage ArrayYou can cable the storage array to host servers with:• Single path data configuration — A single path configuration allows you to connect a maximum ofeight hosts. This is a non-redundant configuration.• Dual path data configuration — A dual path configuration allows you to connect a maximum of fourhosts.Choose the data configuration based on:• Number of hosts required• Level of data redundancy requiredRedundant And Nonredundant ConfigurationsNonredundant configurations are configurations that provide only a single data path from a host to thestorage array. This type of configuration is only recommended for noncritical data storage. Path failurefrom a failed or removed cable, or a failed or removed RAID controller module results in loss of hostaccess to storage on the storage array.Redundancy is established by installing separate data paths between the host and the storage array. Eachdata path is connected to one of the two RAID controller modules installed in the storage array.Redundancy protects the host from losing access to data in the event of path failure, because both RAIDcontroller modules can access all the disks in the storage array.9
