1.1

Features

The Sun Storage J4500 array is a mid-level, modular, rack-optimized, expansion storage solution in the Sun storage product family. It is designed for deployment into commercial server markets in a slide-mounted, horizontally biased enclosure for rack cabinet installations, primarily in datacenter locations.

TABLE 1-1

summarizes the features of the Sun Storage J4500 array.

Description

Up to forty-eight 3.5-inch SATA II drives, of 500 GB, 750 GB or 1 TB capacity each (48 TB total system capacity), 3 Gbit/sec data rates, hot-pluggable.

The System Controller contains four LSI™ SAS x36 expanders. These expanders provide a redundant set of independent SAS fabrics (two expanders per fabric), enabling two paths to the J4500 array’s 48 drives.

Four external mini-SAS x4 (by four) connector ports, each connector contains four PHYs (physical links) enabling eight SAS lanes per fabric to connect to storage. Each x4 connector port links to all 48 disks.

The expander firmware is upgradable (see

Chapter 3 ). The System

Controller module is hot-pluggable.

RAID support is specific to the supported host bus adapter.

The SAS interface allows 1.5 and 3 Gbit/sec SAS and SATA with auto-negotiation.

Up to 48 Gb/sec total bandwidth:

2 (x4-wide) SAS host/uplink ports (24 Gb/sec bandwidth)

2 (x4-wide) SAS expansion port (24 Gb/sec bandwidth)

Supports SSP, STP, SMP as defined in the Serial Attached SCSI (SAS) v1.0

and v1.1 specifications.

Enclosure management is provided through SMP and SES-2.

Four external mini-SAS x4 connector ports (a two-port primary path and a redundant two-port secondary path).

Two 1500 W DC max output power supplies, two bays, 1+1 redundancy

(array continues to operate with one power supply), hot-swappable.

110–220 VAC input voltage

47-63 Hz input frequency

1100 W DC max power consumption

Five variable-speed fan modules (two per module), hot-swappable.

Additionally, each power supply has its own fan.

Cooling is front-to-back forced air.

Two mini-SAS x4 SFF-8088 cables are supplied with the array.
