Digi-Data Fibre Sabre 2300 RAID Systems Deliver More Than 160 MB/second Sustained Disk Performance.Business Editors/Hi-Tech Writers JESSUP, Md.--(BUSINESS WIRE)--May 29, 2001 Digi-Data Corporation announces the availability of the Fibre Sabre 2300 Family of Fibre Channel RAID Systems, which deliver data from disks at a sustained rate over 160 megabytes per second (unit) megabytes per second - (MBps, MB/s) Millions of bytes per second. A unit of data rate. 1 MB/s = 1,000,000 bytes per second (not 1,048,576). . The heart of the Fibre Sabre 2300 RAID Systems is Digi-Data's new Fibre Sabre 2300 RAID controller A disk controller card that supports one or more RAID configurations. Originally only for SCSI drives, RAID controllers have become very popular for PATA and SATA drives. See RAID. , which complements its 2-gigabit per second host interface with a powerful internal memory architecture. Digi-Data's Fibre Sabre 2300 RAID Systems push several dimensions of the technology envelope to provide industry-leading performance, unmatched data availability Refers to the degree to which data can be instantly accessed. The term is mostly associated with service levels that are set up either by the internal IT organization or that may be guaranteed by a third party datacenter or storage provider. , and multiple configuration options to support demanding storage requirements in direct attached and Storage Area Network configurations. Performance: The Fibre Sabre 2300 RAID systems employ a unique internal architecture that uses six disk channels to read or write to multiple disks simultaneously. Using high performance 10000 and 15000 RPM disks, the Fibre Sabre 2300 delivers more than 160 MB/second sustained throughput from disks even in entry level configurations with 5 disks (4 data disks and 1 parity disk). With its special hardware parity generation circuit, the Fibre Sabre 2300 RAID System also provides very high disk write speeds to support applications like video recording and real-time data Real-time data denotes information that is delivered immediately after collection. There is no delay in the timeliness of the information provided. Some uses of this term confuse it with the term dynamic data. collection. Reliability/Data Integrity: In addition to standard RAID features like automatic detection of failed disks, power supplies, and fans with hot swappable See hot swap. replacement, Digi-Data Fibre Sabre 2300 RAID Systems offer advanced data integrity features such as real-time hardware regeneration of data lost as a result of disk failure and global hot spare disks that provide parity protection even after several disk drives fail. With these benefits, the Digi-Data Fibre Sabre 2300 RAID Systems survive and continue to operate without losing performance after a single disk failure, multiple disk failures (as many as one-third of the disks in an array), or a disk channel failure. Configurability: Digi-Data Fibre Sabre 2300 RAID System configurations range from small systems providing 72GB of usable disk space to large arrays providing over 10 TB of usable disk space. Using a fiber optic interface, Fibre Sabre 2300 RAID Systems connect to Fibre Channel switches Major manufacturers of Fibre Channel switches are: Brocade, Cisco, McData and Qlogic.
The components of the Fibre Sabre 2300 RAID System are standard 19-inch rackmount enclosures for ease of installation in computer environments. Additional Features: The Digi-Data Fibre Sabre 2300 RAID Systems provide a number of additional features critical to many demanding storage applications. These include: -- NETMONITOR - Remote network and modem RAID management and e-mail notification -- World Wide Number/LUN Masking - Limits LUN access to hosts with user specified World Wide Numbers -- ARMOR - Software RAID management Graphical User Interface for PCs -- LUN Scrubbing - Automatic scheduled background verification of LUNs to locate and handle bad blocks on disks before they are encountered in normal operation "We designed the Digi-Data Fibre Sabre 2300 RAID Systems to meet the highest performance and reliability requirements of challenging applications, such as video streaming See streaming video and video stream. and broadcasting, image storage and management, continuous data recording, geophysical data processing data processing or information processing, operations (e.g., handling, merging, sorting, and computing) performed upon data in accordance with strictly defined procedures, such as recording and summarizing the financial transactions of a , digital prepress, web hosting Making a Web site available on the Internet. Many ISPs host a few personal Web pages for an individual at no additional cost above the monthly service fee, but the address is subordinate to the ISP; for example, www.friendlyisp.com/pat_smith. , and financial information systems," said Dr. Tomlinson Rauscher, President of Digi-Data. "With the capabilities of our RAID systems, users are undertaking projects that heretofore have been technologically infeasible or cost prohibitive."
