Key Benefits

High performance
Your application's appetite for data at ever-increasing rates can now be satisfied with high performance RAID data transfer, capable of driving Ultra2 SCSI and Fibre Channel to its bandwidth limits. Optimized for high performance, the K-series flexible architecture combines 80 MBytes/sec Ultra2 SCSI (LVD) or optional 100 MBytes/sec Fibre Channel host interface, with two or three Ultra2 SCSI device channels. A 200 MHz CPU with 64 Kbytes unified cache and Chaparral's dual-PCI XOR SDRAM memory controller are incorporated in the K-Series products. This technology is ideal for servers running I/O-intensive applications as well as sequential volume streaming.

Ease of Integration
The new, compact 5.25-inch half-height canister packages the controller, NiMH cache battery backup, integrated fan, LCD/LED/push button front panel, and Ultra2 SCSI termination on-board for easy integration into a standard drive slot. These features enable users to easily configure RAID storage in enclosures physically separated from the server. No special backplane design is needed - simply install the unit into a standard 5.25-inch half height drive bay.

Advanced availability
Supporting RAID levels 0, 1, 3, 4, 5, 0+1 and JBOD, Chaparral's RAID technology ensures high data reliability and performance. Additional features include: OCE (Online Capacity Expansion), SCSI Reserve and Release for multi-initiator array access, spare pooling, ECC-protected disk cache, and hot-swap replacement of disk drives and controllers.

The K-Series RAID Controllers' extensive feature set supports SAF-TE environmental monitoring with even notification via e-mail, pager, fax or automatic calls. Also included are event logging and SMART event monitoring.

Investment Protection
Each controller supports up to 15 disk drives per channel, for a total up to 45 devices in flexible array configurations. Chaparral's architecture utilizes a common hardware platform with a personality interface module for either Fibre Channel or SCSI.

Simple Management
The K5412 and K7413 array controllers feature an easy-to-read menu-driven LCD display of array/drive status and statistics, and array configuration commands. LEDs indicate host and device channel activity and controller status.

The K5412 and K7413 support remote array management and environmental monitoring through LCD host (SCSI or Fibre Channel) port and serial port (RS-232) interfaces. Arrays can be configured, monitored, and managed using Chaparral's Disk Array Administrator embedded software. These features are accessible through an RS-232 port to a PC or VT100 terminal. Support is also provided over the SCSI or Fibre Channel host channel for third-party implementation of GUI utilities by applying Chaparral's Configuration Application Programming Interface (CAPI) Developer's Kit.
