Dell today introduced the PowerVaultTM MD3000, a versatile, direct-attached storage array delivering high performance and high availability for critical applications. The PowerVault MD3000 is the first external RAID SAS array from a tier-one storage system company. "Direct attach storage is incredibly important to a large number of customers. With its performance and advanced software capabilities, the MD3000 will redefine how customers look at DAS," said Darren Thomas, vice president and general manager of Dell storage and services. "At Dell, we want to change the economics of storage by providing easy-to-use, highly-capable storage at new levels of affordability." The expandability, availability, advanced snapshot and virtual disk copy functionality of the PowerVault MD3000 make it an ideal platform for clustered applications such as Microsoft SQL Server 2005 and Microsoft Exchange Server 2007. In addition, these applications are including more advanced replication capability in the software itself. The MD3000 complements this by providing easy-to-use and highly-capable storage at a fraction of the price of storage area networks. Added to this, the PowerVault MD3000 uses dual active/active RAID controllers to enhance performance and availability - producing up to 1,400 MB/s of throughput and approximately 90,000 input/output operations per second (IOPS).1 The throughput performance aids applications such as video services and file serving while the high IOP/s make it ideal for applications with high transactional performance requirements - such as databases and email applications. Dell Leading with Standards The PowerVault MD3000 is Dell's second storage product to comply with the Storage Bridge Bay 1.0 specification. Dell is a founding member of the Storage Bridge Bay (SBB) Working Group that is dedicated to developing industry standards that help accelerate the adoption of new storage technologies and deliver enhanced quality and affordability.

PostgreSQL reached version 8.2. Here is the official release: The PostgreSQL Global Development Group today announces the release of version 8.2 of the PostgreSQL object-relational database management system. This 14th public release adds features, maturity, and performance requested by business users, delivering manageability comparable to leading enterprise database systems. Version 8.2 is expected to drive even more migrations toward PostgreSQL. "This release touches almost every command and database facility," said PostgreSQL core team member and EnterpriseDB database architect Bruce Momjian. "It adds expanded, compatible syntax and interfaces which have been requested by our community, making it easier for new DBAs to fully use all of PostgreSQL's advanced features." "Unisys is pleased to note significant enhancements in the scalability and performance of PostgreSQL on large-scale multi-processor systems," states Ali Shadman, vice president and general manager, Open Source Solutions, Systems and Technology, Unisys. "The newly released 8.2 version continues the maturation of PostgreSQL into a database management system capable of enterprise adoption." New tools and features to make database management and development easier include: Performance improvements: version 8.2 improves performance around 20% overall in high-end OLTP (online transaction processing) system tests. Users can gain even more in data warehousing efficiency. The changes include faster in-memory and on-disk sorting, better multi-processor scaling, better planning of partitioned data queries, faster bulk loads and vastly accelerated outer joins. Warm Standby Databases: through an extension to our Point in Time Recovery feature (introduced in version 8.0), administrators now can easily create a failover copy of your database cluster. Online Index Builds: index builds can now occur while applications write to database tables, allowing performance tuning without downtime. SQL 2003 Features: Postgr

Infrant Technologies, a leader in network-based storage for home and small business use, today announced its latest Network Attached Storage (NAS) offering for businesses ranging from small and mid-sized offices up to small and mid-sized enterprises concerned with protecting data in a power- and space-efficient manner. The ReadyNAS 1100 is a new class of NAS. Building on Infrant's award-winning pedigree, it is perfect for archiving data or day-to-day department and workgroup activities. The ReadyNAS 1100 sports an incredibly compact 12-inch-deep field serviceable 1U chassis (enabling back-to-back mounting in a four-post data rack) and has a typical power consumption of 75 watts with four hard drives, so a 20 AMP rack of 1100s touts 90 terabytes of storage. Additionally, the 1100 has dual 1-Gigabit Ethernet ports, full-hardware RAID (0, 1, 5, X-RAID) acceleration and the ability to support up to four hot-swappable SATA hard drives. The 1100 also features sequenced hard drive power on, which protects the unit from "start-up surging." The ReadyNAS 1100 is built around an enterprise-hardened embedded Linux operating system and Infrant's custom network storage processor (NSP), requiring no additional software installation or per-user licensing agreements. The 1100 has three security modes (share, user and domain for ADS integration), providing additional security to the network. It also has built-in system monitoring with e-mail alerts to keep administrators apprised of the status of the unit. Its browser-based administrations screens facilitate centralized management. The 1100 has a journaling file system to ensure data integrity so that in the event of a system failure, all of the data can be quickly restored to its pre-crash configuration. Additionally, the 1100 is backed by a dedicated team of engineers to assist with any integration issues. "The introduction of our second-generation ReadyNAS 1100 is based on the valuable feedback from our existing ReadyNAS customer
