The 5U84 Primary Storage Shelf uses two SAS-3 RAID controllers, which are located in the top two slots of the back panel. The RAID controllers provide RAID data protection technology for the data that is stored on the 5U84 Primary Storage Shelf disk drives. The RAID controllers also provide RAID data protection technology for the optional 5U84 Expansion Storage Shelves that you connect to the 5U84 Primary Storage Shelf.
SAS-3 copper cables connect the 3340 Appliance compute nodes to the 5U84 Primary Storage Shelf through the storage shelf's RAID controllers.
Five high performance fan modules connect to the storage shelf's midplane connector through the middle slots. Each fan module contains two contra-rotating high performance fans, along with separate power and control circuits for each internal fan.
Two redundant Power Supply Units (PSUs) are located in slots beneath the fan modules.
To operate, the 5U84 Primary Storage Shelf must have at least one functioning RAID controller, one functioning power supply unit, and four functioning fan modules.
The 5U84 Expansion Storage Shelf uses two Expansion I/O modules, which are located in the top two slots of the back panel. The Expansion I/O modules provide SAS-3 I/O data transfers between the 5U84 Primary Storage Shelf and the 5U84 Expansion Storage Shelf. The Expansion I/O modules also provide I/O data transfers between the first 5U84 Expansion Storage Shelf and up to two additional 5U84 Expansion Storage Shelves.
SAS-3 cables connect the 5U84 Expansion Storage Shelf to the 5U84 Primary Storage Shelf through the 5U84 Expansion Storage Shelf's Expansion I/O modules. SAS-3 cables are also used to daisy chain up to two additional 5U84 Expansion Storage Shelves to the first 5U84 Expansion Storage Shelf.
Five high performance fan modules connect to the storage shelf's midplane connector through the middle slots. Each fan module contains two contra-rotating, high performance fans, along with separate power and control circuits for each internal fan. The device must have at least one functioning RAID controller, one functioning power supply module, and one functioning fan module.
Two redundant Power Supply Units (PSUs) are located in slots beneath the fan modules.
To operate, the 5U84 Expansion Storage Shelf must have at least one functioning Expansion I/O module, one functioning PSU, and four functioning fan modules.
