DPT launches enhanced SmartCorrect ECC-protected memory for unsurpassed protection of storage subsystems.MAITLAND, Fla.--(BUSINESS WIRE)--Oct. 1, 1996--Distributed Processing Technology (DPT) Tuesday announced that its exclusive Error Correcting Code (ECC (1) (Error-Correcting Code) A type of memory that corrects errors on the fly. See ECC memory. (2) (Elliptic Curve Cryptography) A public key cryptography method that provides fast decryption and digital signature processing. )-protected memory now includes protection down to the drive level for DPT-certified third-party disk drives. Previously, this comprehensive protection was only available when implemented with DPT's SmartRAID disk drives and subsystems. DPT's enhanced SmartCorrect SIMMs and DIMMs -- used on its SmartRAID IV and SmartCache IV adapters -- boasts the industry's only ECC-protection for the entire mass storage subsystem The part of a computer system that provides the storage. It includes the controller and disk drives. See storage system. , including across the SCSI SCSI in full Small Computer System Interface Once common standard for connecting peripheral devices (disks, modems, printers, etc.) to small and medium-sized computers. SCSI has given way to faster standards, such as Firewire and USB. cable, the weakest link in the storage subsystem. SmartCorrect ECC-protected memory enables DPT's high-performance SmartCache IV or SmartRAID IV adapters to detect and correct any data corruption Data corruption refers to errors in computer data that occur during transmission or retrieval, introducing unintended changes to the original data. Computer storage and transmission systems use a number of measures to provide data integrity, the lack of errors. within the adapter's cache and data paths. DPT's exclusive SmartCorrect ECC-protected memory provides enhanced data security and integrity, although SmartRAID IV and SmartCache IV products also accept standard memory. "DPT is aggressively marketing its exclusive SmartCorrect technology," said Johnny Cardosi, vice president of distribution sales and marketing. "With the complexity of systems and the cost of system downtime increasing people realize that the cost of corrupted data or downtime easily justifies the additional investment for extended fault tolerance See fault tolerant. (architecture) fault tolerance - 1. The ability of a system or component to continue normal operation despite the presence of hardware or software faults. This often involves some degree of redundancy. 2. ." Data corruption can be caused by any nearby electrical interference that may affect a PC. Additionally, the new PCI-Ultra/Wide SCSI technology can also exacerbate SCSI bus signals. The popularity of hot-swappable SCSI devices in mission-critical RAID systems further aggravates this problem by creating another source of noise on the SCSI bus, resulting in SCSI bus data errors. Providing additional ECC-protection across the SCSI cable and down to the drive level is key to preventing data loss or down time in any of these situations. "Combining DPT's SmartCorrect technology with DPT's RAID offers users the ultimate in fault tolerance for a storage subsystem," said Cardosi. "Other major suppliers of RAID systems, such as IBM (International Business Machines Corporation, Armonk, NY, www.ibm.com) The world's largest computer company. IBM's product lines include the S/390 mainframes (zSeries), AS/400 midrange business systems (iSeries), RS/6000 workstations and servers (pSeries), Intel-based servers (xSeries) or Hewlett-Packard, do not offer ECC-protection, Compaq's ECC-protection does not include the SCSI bus, and certainly none of these competitors offer this level of protection with third-party disks and subsystems. We believe that opening our ECC technology to a broader market will cement our position as the premier supplier of highly fault tolerant The ability to continue non-stop when a hardware failure occurs. A fault-tolerant system is designed from the ground up for reliability by building multiples of all critical components, such as CPUs, memories, disks and power supplies into the same computer. RAID systems." ECC is a data protection scheme that has the ability to detect and correct data corruption. ECC algorithms create an ECC code, or checksum A value used to ensure data are stored or transmitted without error. It is created by calculating the binary values in a block of data using some algorithm and storing the results with the data. , based on the data to be protected. Later, if the data becomes corrupted, SmartCorrect utilizes the ECC checksum to identify and correct the corruption. ECC's ability to correct corrupted data is the main feature that differentiates ECC from parity protection. Because DPT's ECC functionality is implemented in hardware, server performance is never impacted. Installing ECC SIMMs or DIMMs on SmartRAID IV or SmartCache IV activates the ECC feature. When data enters the controller, it automatically appends an ECC checksum to that data. This ECC checksum protects that data within the DPT controller, including its data path and cache. For DPT's exclusive subsystem-wide ECC-protection, the following component are required: SmartRAID IV 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. or SmartCache IV high-performance adapter; SmartCorrect ECC-protected SIMMs or DIMMs, DPT-certified disk drive; and DPT's Storage Manager Software.
