Adaptec launches new series 2 RAID controller for Linux
ADaptec launches new entry-level offerings based on UNIFIED SERIAL RAID controller PERFORMANCE ARCHITECTURE New Series 2 Low-Profile Controllers Leverage Series 5 Design and Deliver Hardware RAID 0, 1, 10 for SATA and SAS Disk and Tape-Based Applications MILPITAS, Calif. - May 13, 2008 - Adaptec Inc., (NASDAQ: ADPT), a global leader in storage solutions, today unveiled a new family of entry-level Unified SerialT RAID controllers. The new low-profile Series 2 RAID controllers, built on the same Adaptec industry-leading dual core RAID-on-Chip (ROC) architecture used in its successful Series 5 RAID controllers, provide significant performance enhancement and scalability to low-cost data storage systems. The Series 2 controllers eliminate the limitations of software RAID-based hardware solutions commonly found in entry-level systems, delivering a wide range of advantages for inexpensive SATA and SAS disk and tape drive systems. This includes offering the superior performance of advanced hardware RAID 0, 1 and 10 independent of the server and its operating system; a dramatic increase in data storage system configurability through the controllers' innovative internal and external port architecture; greater support of Open Source drivers; and no vulnerability to viruses. With these controllers, Adaptec provides system integrators, value-added resellers, OEMs, and enterprise data centers with the ability to meet a wide range of data storage I/O (input/output) requirements using entry-level systems. "The Adaptec Series 2 family is critical to our comprehensive line of Unified Serial RAID controllers," said Suresh Panikar, director, Worldwide Marketing, Adaptec. "Customers who have specific storage needs - increased RAID performance for disk drives, tape backup, or are working with applications based on Linux - will find our Series 2 controllers exceed those needs." The new controllers offer complete compatibility with more than 300 SATA/SAS devices, including midplanes, disk drives, and tape drives. Series 2 controllers are also "plug and play" compatible with Linux drivers 2.4.2 or later. "We are committed to providing best-in-class SAS tape drive solutions, and the compatibility and performance of the new Series 2 Adaptec controllers is an ideal complement to our LTO family of internal and external SAS tape drives," said Bharat Kumar, vice president of Worldwide Marketing and Development, Tandberg Data. "We will continue to work closely with Adaptec to ensure our SAS tape drives, coupled with the Series 2 controllers, meet the performance and needs of our customers." Adaptec RAID Series 2 controllers are engineered to deliver the industry's most cost-effective solution for increasing data storage access and scalability. Equipped with 128MB of DDR2 cache, customers can connect up to 128 SATA/SAS I/O devices, including disk drives or tape drives using SAS expanders. The Series 2 family integrates the latest PCIe connectivity, the broadest operating system support, including embedded open source Linux drivers and proven compatibility. Pricing and Availability The Series 2 family consists of three products: the Adaptec RAID 2405 Kit (US$250) with four internal ports, the Adaptec 2405 Single (US$225) with four internal ports, and the Adaptec 2045 Single (US$250). Adaptec Series 2 kits include a fanout cable. All cards will be shipping and available through worldwide distributors and resellers by May 30, 2008. Both cards integrate Adaptec Storage Manager TM (ASM) software. ASM centralizes management of Adaptec RAID products. Cards installed in one or more servers can be configured, managed and monitored remotely from a single client workstation through secure, encrypted communications. The intuitive RAID management tool provides pop-up tips and online help to simplify the creation and management of RAID arrays. About Adaptec Adaptec, Inc. (NASDAQ: ADPT) provides trusted storage solutions that reliably move, manage, and protect critical data and digital content. Adaptec's software and hardware-based solutions are delivered through leading channel partners and Original Equipment Manufacturers (OEMs) to provide storage connectivity, data protection, and networked storage to enterprises, government organizations, medium and small businesses worldwide.

Adaptec launches new series 2 RAID controller for Linux Posted May 25, 2008 11:03 UTC (Sun) by muwlgr (guest, #35359) [Link] Software RAID in Linux is excellent (I use mdadm/raid1 on every averagely serious system under my control), as well as in Windows, and its advantage is that it is always with you, on every hardware. Contrary, your expensive HW RAID card can go down, become obsolete and unsupported with years, and so on - certainly there are reasons to pull your hairs off your head and body. With HW RAID you should always plan yourself for future replacement/migration of your hardware. And remember that not everyone complies to SNIA/DDF metadata format. With SW RAID, your OS supports your new hardware for you.
Adaptec launches new series 2 RAID controller for Linux Posted May 26, 2008 1:48 UTC (Mon) by dlang (✭ supporter ✭, #313) [Link] with software raid the CPU must handle all the data (potentially multiple times when doing read/modify/update or when writing to multiple drives) while with hardware raid the data only needs to be sent to the card once (usually more a factor with raid 1 or 1+0 arrays) this is an advantage if you are pushing buss speed limits with hardware raid you can get battery-backed cache, which can make your data about as safe as on a hard drive at almost the speed of a ramdisk this can be a huge advantage if you are fsync limited (mail servers, databases, etc) with hardware raid you don't have to do anything if a drive fails to keep going (including booting), with software raid you have to jump through some significant hoops to boot from a different drive than the one the BIOS normally boots from. on the other hand hardware raid is expensive. in most cases limited in the number of drives you can put in one array. (you are usually limited to the number of drives you can attach to the one card) If you aren't careful in testing the hardware raid you may find that it becomes the performance bottleneck. Many raid cards are only decent at raid 0/1, some are incredibly bad when doing raid 4/5/6 Many raid controllers don't support raid 6. there are advantages and disadvantages to both approaches. I use both (sometimes in the same box) don't believe anyone who trys to tell you that one is always right.
