Adaptec FS4500 RAID

The Adaptec FS4500 Fibre to SATA RAID addresses the high growth, midrange storage market, combining cost-effective SATA technology with Fibre Channel RAID performance and reliability in SAN and DAS configurations. It is ideal for reference data and fixed content applications where data availability, throughput and constant access to storage resources are critical. The FS4500 is highly flexible and configurable to adapt to evolving storage requirements with flexible configurations.

Note: Only drivers that are not included or embedded within a supported operating system are listed below. To see a complete list of supported operating systems see the Product Specifications

Select your operating system or software below

Supported Operating Systems
	Microsoft Windows NT 4.0 Microsoft Windows 2000 Microsoft Windows Server 2003 Red Hat Linux AS 3.0

Benefits
	No single point of failure with redundant, hot-swappable components and a passive midplane. RAID controllers mask the drives’ SATA characteristics, presenting them to the host as high performance FC devices.

Key Differentiators
	Combined performance and connectivity benefits of Fibre Channel with the cost advantages of SATA drives. Passive, 3Gbit-ready, midplane.

Customer Needs
	Cost-effective, performance, and flexibility for the midrange storage market

System Environment
	Spheras RAIDWatch management GUI supported under Windows, Linux. OS Independent via serial port management

Capacity
	Up to a maximum of 12 drives (4.8 TB) capacity per 2U enclosure with a total maximum of 96 drives (34.8 TB) capacity per subsystem

Network or Host Interface
	One or two Fibre Channel controllers; each controller supports dual optical or copper (SFP) connections, 200 MB/s each (400 MB/s total) Serial (RS232) port, Ethernet port, copper or optical (SFP) expansion port

Data Transfer Rate
	Dual controllers: Up to 385 MB/s (sustained reads), 48,000 I/Os (cached reads)

Package Contents
	Storage enclosure with either one or two controllers Quick Install Guide CD containing management software and user documentation (Disk drives sold separately)

Warranty
	3-year warranty on subsystems (3 year warranty on SATA disk drives)

Disk drive interface

Independent 150 MB/s point-to-point connections to each SATA disk drive with dual port access to each drive and failover by each controller to each drive.
