Mylex's DACFF incorporates the latest technology to support the fault tolerance of clustering, as well

as the performance and efficiency of SANs. The controller provides an end-to-end Fibre Channel

interface between the host computer and the disk drives, and delivers almost four times the I/O

performance of traditional Ultra SCSI controllers. With dual active, automatic failover/failback host

cluster support via two copper FC-AL (Fibre Channel Arbitrated Loop) channels, the DACFF

enables flexible configuration and redundant connections for high-availability applications. In addition

to supporting automatic failover/failback, DACFF provides support for four other critically important

clustered storage capabilities, including active-active operation, mirrored write caching, scalable I/O

performance and scalable I/O capacity.

At Computex, Mylex will demonstrate how the DACFF can achieve fault-tolerance through the

redundancy of a clustered environment. The dual-active DACFF running at 190 MB per second will

be clustered with two Acer servers, Seagate (NYSE:SEG news) disk drives and a Sagitta Salient

external storage subsystem.

Mylex also will demonstrate its award-winning, highly scalable, internal PCI RAID controller, the

eXtremeRAID 1100, in a PCI clustering environment with two Acer servers. eXtremeRAID 1100

significantly eliminates I/O bottlenecks between the storage and controller; at the controller; and

between the controller and the server. eXtremeRAID 1100 integrates several advanced technologies,

including Mylex firmware, a 233MHz Intel (Nasdaq:) StrongARM on-board RISC processor, a

64-bit PCI bus and multiple Ultra2 SCSI LVD buses. The controller delivers performance greater

than 8,000 I/Os per second as compared to the 2,500 I/Os per second typical of many other

mid-range and high-end controllers.

At Computex, Mylex will also exhibit its roadmap for eXtremeRAID 1100's support of the new Ultra3

and Ultra 160/m SCSI standards.

eXtremeRAID 1100 and its predecessor, the Mylex DAC960PJ, have helped several of the leading

server vendors establish TPC-C and TPC-D world records for performance and price/performance.

Mylex recently announced that eXtremeRAID 1100 helped Acer set a world TPC-C record in

price/performance for its AcerAltos 21000 server. On May 17, Windows NT Magazine honored

eXtremeRAID 1100 by choosing it as an Editor's Favorite.

At Computex, Mylex will exhibit its AcceleRAID family, a low cost line of controllers that offer many

of the same high performance and fault tolerance features typical of expensive high-end RAID

controllers. AcceleRAID's low cost is achieved by utilizing the on-board SCSI channels of Intel's

next-generation motherboards. AcceleRAID supports Ultra2 SCSI and features Mylex's advanced

RAID architecture, which includes an Intel RISC processor, a monolithic NT driver and Mylex

firmware. AcceleRAID's aggressive price-point provides the opportunity for Mylex's distributors,

resellers and OEM customers to offer the benefits of RAID to a broader range of customers, such as

entry-level server and workstation users.

eXtremeRAID 1100 is available in two and three channel configurations with MSRP pricing starting at

$1,395 for a two-channel configuration. The AcceleRAID family consists of the AcceleRAID 150,

200 and 250 models, with MSRP for the family starting at $499. eXtremeRAID 1100 and the

AcceleRAID family can be purchased through Mylex's worldwide channel network, which includes

distributors, resellers and systems integrators. For a complete list of authorized Mylex distributors, visit

The DACFF carries an MRSP starting at $6,410 and, in addition to the eXtremeRAID 1100 and

AcceleRAID family, is also available through Mylex's worldwide team of PC server OEM partners.

The controllers support all major operating systems, including Windows NT, Linux (through third

parties), NetWare, SCO UNIX, UnixWare and OS/2.
