Mylex boosts RAID controller performance
Hoping to add to its record-setting benchmarks, Mylex is expected to introduce next month a souped-up RAID controller that significantly boosts the performance of its existing DAC960PJ. Compared to the DAC960, the new eXtremeRAID 1100 controller uses a 233MHz StrongARM processor (vs. a 66MHz i960), sports an 80MBps Ultra 2 LVD SCSI interface (vs. 40MBps Ultra SCSI), and supports a 64-bit PCI bus (vs. a 32-bit PCI bus). Mylex claims 6,000 I/Os per second, compared to 2,500 I/Os per second for the DAC960PJ, based on Intel`s IOmeter benchmark test.
Although it has a 64-bit PCI bus, the controller will also work with 32-bit PCI buses, eliminating the need for a separate controller. Based on DAC960 core technology, the eXtremeRAID controller adds a number of other features, including support for Windows NT clusters, PCI Hot Plug capability, and background initialization, which Mylex claims can reduce initialization time to five minutes.
Each controller supports up to 810GB and works in NT, SCO UNIX, and NetWare environments. OEM shipments are scheduled for next month, with shipments to the distribution channel due in the fourth quarter. Pricing had not been finalized at press time. www.mylex.com.
