InfiniBox features off-the-shelf hardware components, allowing for a quick adoption of newer, faster hardware components.

Available layouts

Common components

Each InfiniBox layout contains an array of 3 storage controllers (nodes), 3 BBUs and a service drawer. The storage controllers are connected to each other via an InfiniBand network. Each storage controller is equipped with RAM, Flash Cache and internal disk drives in various configurations.


The InfiniBox layouts are equipped with 1,2,4 or 8 drive enclosures; each contains 60 disk drives. The available sizes are 3,4,6 or 8 TB. InfiniBox offers a variety of capacity options, starting with a single enclosure of 60 disk drives with a disk size of 3 TB, all the way up to eight enclosures of 60 disk drives each, at the disk size of 8 TB.

Rack layout

The following image displays the various InfiniBox rack layouts. 

InfiniBox Power Feed

Hardware Terminology

  • PDU - Power Distribution Unit. An electrical appliance that receives power from the data center and provides multiple power outputs to feed the InfiniBox appliances. 
  • ATS - Automatic Transfer Switch. An electrical switch that selects the power source between two PDUs to feed the BBU in such a way that each of the BBU is fed from redundant power sources.
    The ATS is located within the Utility Drawer.
  • BBU - Backup Battery Unit. Provides electrical power in case no power arrives from the data center, allowing InfiniBox to gracefully shutdown and protect user data.
  • Node - A Storage Controller. The InfiniBox component that receives I/O from hosts and controls the way data is stored. InfiniBox has three nodes in Active-Active-Active formation for maximum redundancy.
    Nodes are fed from the BBU. Nodes may include SSD drives for Read Cache.
  • Enclosure - A fully redundant storage enclosure that contains 60 drives.
    The Enclosures are power consumers. Enclosures are fed from redundant PDUs.

Power Distribution Unit (PDU)

The InfiniBox PDUs receive power from the data center in one of the following ways:

  • 4x single phase PDUs: 2 on each side of the InfiniBox, that are fed from above or below the rack.
  • 2x three-phase PDUs: 1 PDU on each side, that is fed from above or below the rack.


The PDUs feed the ATSs in either of the following configurations:

  • PDU - 4 * 1PH / 2 * 3PH
  • ATS - 3
  • Connectivity 
    • 2 PDUs connected to 1 ATS
    • 2 PDUs connected to the other two ATS (each PDU is connected to both ATS)


Each ATS feeds each of the BBUs (a single ATS feeds a single BBU).

  • ATS - 3
  • BBU - 3
  • ConnectivityAn ATS per BBU

PDU to Enclosure(s)

Each enclosure is fed from two different PDUs.

BBU to Nodes

Each BBU feeds two Nodes. Each of the nodes is fed by two BBUs. Thus, in case of a single BBU failure, all three nodes remain active:

  • 2 BBUs keep 3 Nodes active.
  • 1 BBU keeps 2 Nodes active.

Enclosures and Drives

1,2,4 or 8 Enclosures. Each contains 60 drives:

  • Ultra-dense 4U
  • 60 NL-SAS HDDs, hot-pluggable
  • 2 x hot-pluggable, redundant I/O controllers equipped with redundant 6Gbps, 2.0 SAS connections
  • 2 x hot-pluggable, redundant power and cooling modules
  • Two independent AC power inlets


Support the nodes during power loss, allowing enough time for the notes to gracefully shut down

  • Provide power to allow the nodes to shut down gracefully in an event where the two power sources are lost
  • When power returns, the system is powered on automatically

Drive Visibility

Each node has direct access to all drives.

The Patch Panel

The InfiniBox patch panel is located on the rear side of the rack. The patch panel layout includes three sets of cable ports, one for each node.

Each of the nodes may include:

  • 8 FC ports
  • 4 Ethernet ports (copper or optic)
  • 1 management port for the InfiniBox Management Suite

Port 15 located on Node-3 is used for connecting VPN to the Support Appliance for remote connectivity

The Service Drawer

The Service Drawer contains the following components:

  • ATS - the ATS is fed by the PDU and feeds the BBU as discussed above
  • Support Appliance (on a fit-PC)
  • Internal system Ethernet switch
