Adaptec 51245 SAS RAID ControllerSerial Attached SCSI, Serial ATA/300PCI Express x8Plug-in Card 2268200-R
Product Description 16-port (12 internal/4 external), half length/full height, PCI-Express (PCIe) Unified Serial RAID controller with Intelligent Power Management delivers exceptional performance, advanced data protection, and maximum scalability for enterprise-class applications. From the Manufacturer With an industry-leading dual core RAID on Chip (ROC), DDR2 533MHz write cache, support for up to 256 SATA/SAS devices (using SAS expanders), and an x8 PCI Express host interface bus connection, the Series 5 controllers delivers impressive performance numbers--over 250,000 I/Os and 1.2GB/s. These controllers are ideal for enterprise-class storage applications that call for maximum performance, scalability and flexibility. The Adaptec RAID 51245 utilizes industry-leading dual core RAID on Chip (ROC), 512MB of DDR2 write cache, and connectivity with the latest x8 PCI-Express to deliver over 250,000 I/Os 1.2GB. Using SAS expanders, it can connect up to 256 SATA/SAS devices. The Adaptec RAID 51245 supports a broad range of operating systems, compatibility with more than 300 third-party devices, and full integration with Adaptec Storage Manager for centralized management of all Adaptec RAID controllers on the network. Highest Performance Series 5 controllers deliver speeds up to five times faster than competing products--over 250,000 IOPs and 1.2GB/s--making them ideal for enterprise-class storage systems. The Adaptec RAID 51245 utilizes industry-leading dual core RAID on Chip(ROC) connectivity Advanced Data Protection Adaptec RAID Code (ARC) delivers maximum reliability with RAID levels 0, 1, 1E, 5, 5EE, 6, 10, 50, 60 and JBOD. ARC also offers RAID Level Migration (the ability to easily migrate RAID levels), Online Capacity Expansion (expand capacity without powering down the server), and Copyback Hot Spare (when a failed drive has been replaced, data is automatically copied from the hot spare back to the restored drive). Hybrid RAID With Hybrid RAID 1 & 10 the Series 5 controllers offer maximum performance and reliability by combining Solid State Drives (SSDs) and Hard Disk Drives (HDDs) in a single array. By performing read operations from the faster SSD and write operations on both the SSDs and HDDs the result is tremendous performance gains over standard HDD RAID arrays. Hybrid RAID offers the benefits of both technologies and allows a better cost per GB ratio than comparable SSD-only RAID arrays. The Case for Cache The fastest way for a RAID controller to fulfill a read or write request is to serve data out of its cache. Enabling the RAID controller cache offers significant performance benefits, such as reduced latency in I/O requests, bandwidth and queue depths that surpass software application limits, and on-the-fly parity calculations on sequential writes. Intelligent Power Management The power required by disks is a primary ongoing storage cost. Full power is maintained to every disk whether it is actively being used or not, which also increases cooling costs. Adaptec Intelligent Power Management slashes power and cooling costs by spinning down idle disks and providing a lower power mode for active disks. One-view Storage Management Adaptec Storage Manager, a one-view tool centralizes management of all Adaptec RAID products. Broad Operating System Support Extensive operating system support includes all major software releases, such as Windows, Linux, FreeBSD, and UNIX variants.
