identical with connecting Ethernet network devices either point-to-point to iSCSI initiators or using Ethernet switches.

Other Concerns: - Subnet, gateway, and other access control mechanisms can be applied with the iSCSI port connection.

The RAID subsystem supports connection through Ethernet networks to servers (iSCSI initia- tors) using iSCSI HBAs or SCSI packet processing software compliant with the IETF iSCSI standard (RFC 3720).

Channels: - The SCSI-like ID/LUN mapping method enables users to associate storage volumes with simulated IDs or LUNs on the host channels. On the drive side, all of the twelve (12) SATA drives are connected each through a dedicated SATA channel. Each drive channel is routed to an enclosure drive tray that is equipped with a standard SATA connector with hot- swap capability. The methods used for assembling physical drives, fault management, and sta- tus monitoring are identical to that used with the traditional RAID storage.

NOTICE!

On receiving and unpacking your subsystem, please check the package contents against the included Unpacking Checklist. If any modules are missing, please contact your subsystem ven- dor immediately.

Chassis Overview

i

The RAID storage subsystem chassis is a 2U metal chassis that is divided into front and rear sections. Key components are respectively accessed through front and rear panels. The pre- drilled mounting holes in the sides of the 2U RAID subsystem enclosure allow you to attach separately purchased slide rails so that you can install the enclosure into a standard 19-inch rack or enclosure cabinet.

NOTICE!

Components accessed through the front panel are referred to as “Front Panel Components” and components accessed through the rear panel are referred to as “Rear Panel Compo- nents.”
