Winchester Systems Offers Disaster Recovery Solutions
Affordable Disaster Recovery Up To 120 km

Burlington, MA. November 13, 2001 - Winchester Systems has introduced a series of three fibre channel based Disaster Recovery solutions for IT managers to replicate critical data to remote sites up to 120 km distant.

The company offers three basic configurations. A Workgroup Disaster Recovery solution offers data replication to a mirror server and disk array within a building via point-to-point fibre channel. The Departmental Disaster Recovery solution offers data replication to another site at up to 120 km using switched fibre channel connections. The Enterprise Disaster Recovery solution offers data replication to a remote site with redundant paths and redundant switches for the highest level of fault tolerance and reliability.

"A disaster recovery site needs to record data promptly to avoid impacting the primary application, so the legendary speed of FlashDisk OpenRAID systems for disaster recovery sites make them ideal for this application," according to Mr. Jerry Namery, the company's chief technology officer. "For disaster recovery sites within 120 km, fibre channel connections provide high speed, reliable connectivity for the highest performance, mission critical applications," he added.

Data Replication
With direct fibre channel connections, data can be replicated with simple host based mirroring to independent FlashDisk arrays. For more demanding applications, Winchester Systems offers Veritas Intelligent Disaster Recovery (IDR) software with all of the Disaster Recovery solutions. The Veritas IDR software intelligently manages the data workload across multiple connections to maximize data throughput and to use alternate data paths in the event of path failure. It also permits the primary and disaster recovery sites to run asynchronously to maximize the performance of the primary site.

Data Recovery
When disaster recovery data needs to be retrieved, the network can just access the data directly using either the primary or the secondary server without copying the data. This direct access approach saves countless hours of data copying in the event that the disaster recovery image data is needed.

Field Proven Technology
FlashDisk Disaster Recovery solutions rely only on field proven FlashDisk OpenRAID disk arrays, fibre channel technology, host based mirroring and popular Veritas software. Disaster Recovery solutions can be installed quickly, taking no longer than conventional data storage to install and maintain.

High Performance
Each FlashDisk OpenRAID disk array at the primary or disaster recovery site delivers up to 13,000 sustained disk operations per second and up to 121 Mbytes per second sustained data throughput. For increased reliability with redundant controllers, and higher performance for disaster recovery operations, FlashDisk offers active/active failover RAID controllers. The dual controller configuration delivers higher data throughput with 177 MB per second sustained data transfer.

Centralized Management
All FlashDisk OpenRAID units are easily managed out-of-band over IP using a secure web console, called FlashConsole, for centralized storage management of both primary and disaster recovery sites. FlashConsole enables installation and maintenance of all the storage and server connections and provides error monitoring and alert notification via e-mail and pager.

"Open" Architecture
FlashDisk OpenRAID disk arrays are true hardware, plug-and-play storage. FlashDisk OpenRAID disk arrays are the key storage component of the Disaster Recovery solutions. For simplicity and compatibility, FlashDisk OpenRAID emulates standard disks --eliminating proprietary host software, RAID managers and the need for software drivers or agents of any kind. FlashDisk OpenRAID supports hardware RAID 1, 3, 5, 1+0 and RAID 15 for data protection. The disk arrays attach via industry standard SCSI and fibre channel interfaces to host servers including SUN, HP, IBM, Intel and MAC.

Price and Delivery
A Workgroup Disaster Recovery Solution with two FlashDisk OpenRAID disk arrays with 434.4 MB storage each starts at $38,061 each. Delivery is 2-3 weeks.
