Engine
The engine contains the ISBs, ISSs, IXSs, power supplies, and an internal midplane. The engine
stores the data created and shared by the clients. The data is passed in and out of the engine
through the switches.
The engine contains:
•
ISBs can support either 250 GB, 500 GB, or 1 terabytes (TB) drives, with two drives in each
ISB. The size of the drives are identified by the label on the front of the ISB (i500, i1000,
i2000, i4000, i8000). As technology advances, the storage capacity of the drives could
increase, allowing the total storage per ISB/engine to increase.
•
An ISS provides connections for clients via 1000BASE-T Ethernet ports. A 10-Gb Ethernet
port using SFP+ transceivers connects clients or serves as an uplink port. There is an engine
interconnect port and a management port for configuration. See
•
An IXS used when you have more than two engines (need an IXS for each subnet), allowing
you to connect multiple engines providing up to 384 TB of storage, or 192 TB of mirrored
storage. See
“Integrated Ethernet Switches” on page 29
Engine Front View
The front of the engine allows access to the 16 ISBs. The first is in the upper left portion of the
front and the last ISB is in the lower right.
Each ISB can be removed and replaced separately with the power on.

If you replace an ISB with power on, the LEDs in all of the ISBs go off momentarily. This does
not represent a problem. All functions are still active and working properly.
