External PCIe Attached Raid subsystem takes high performance advantage of PCI Express link with 1000MB/s data throughput (250MB/s per lane & 4 lane simultaneously )connecting simply between memory and Raid set via DMA (Direct Memory Access) schema to reduce CPU resource overhead. A new polynomial RAID 6 tolerates two disk fail at the same time enhancing Data reliability. Combining Raid subsystem and PCI Express card solves compatible issue on cross-platform with various drivers support and breaks limitation of narrow space in server machine by up to 128 HDDs capacity with SAS JBOD scalability, which is suitable and cost-effective solution for such as content creation, multi-stream video editing, multi-media on demand, all required high performance, scalability and data reliability applications

Advanced Key Feature:

Simple
The design is simple by PCI Express to host, SAS/SATA2 to disk. Compare to traditional I/O process such as SCSI. Fibre¡KPCIe Raid simplifies data transmission protocol directly from Memory to HD via DMA scheme to reduce CPU overhead and conversion time and maximum throughput rate. Simple brings low cost ownership and high performance.
Reliable
Raid 6 is an essential extension of Raid 5 with second parity scheme to enhance data availability. In the past experience, IT guys are very afraid when one HD rebuilding under Raid 5 level, the second HD failure detected, which causes the whole Raid set crash and lost all data. That¡¦s why Raid 6 is design two HDs fail tolerance and makes data more reliable without reduce performance.
Scalable
Unlike internal PCIe Raid only supports few HDDs in narrow space of sever machine and worry about high temperature might affect server machine performance. External PCIe Raid breaks space limitation providing 24 Bay external Raid subsystem and SAS expender port can be attached JBOD. Each PCIe Raid supports up 128 TB capacities.
Cross-platformable
YOTTA PCIe provides various drivers for Windows 2000/ XP/ Server 2003/ Vista, Redhat/SuSE Linux, FreeBSD, Solaris 10x86/x86_64, SCO UnixWare 7.1.4, Novell Netware 6.5, ¡§Mac OS 10x¡¨. Especially for Mac User, hardware compatible issue will be no longer headache. Easily install the driver and enjoy extreme performance for any kind editing application.
Performance Achievable
Uncompressed SD 10bit 30-ftps(27MB/s), Uncompressed HD 24-ftps 1080p 10bit(127MB/s), Uncompressed HD 1080i RGB 4:4:4(250MB/s). Stop to wait your data stuck on performance limitation. That¡¦s why AXUS guarantee 800+MB/s performance by PCIe external Raid for you to run any critical performance requirement application.

Enhance Features:

Convenient Modular Designs
RAID controller, cooling fans, disk drives, and power supplies are modular designs and interchangeable within series. They can be easily hot swapped to eliminate the down time of the RAID services.
Multiple RAID Selection
A Volume Set is seen by the host system as a single logical device and is organized in a RAID level with one or more physical disks. Each Raid set can contain multiple volume set with different Raid level and configuration.
Instant Availability/Background Initialization
The operating system can instantly access to the newly created arrays without requiring a reboot or waiting for the initialization to be completed.
Array Roaming
The configuration settings of a RAID will be restored in both NVRAM and the disk drives, providing the maximum protection in case of a disk drive or controller failure. Array roaming allows the administrators to move a complete raid set to another system without losing RAID configuration and data on that raid set. Online Capacity Expansion
Online Capacity Expansion makes it possible to add one or more physical drive to a volume set while the server is in operation, eliminating the need to store and restore after reconfiguring the raid set.
Online RAID Level and Stripe Size Migration
Both the RAID level and stripe size of an existing volume set can be migrated while the server is online and the volume set is in use. The feature makes the RAID configuration change easier during performance tuning or adding extra physical disks.
SNMP
SNMP-based management application (also known as a SNMP manager) can monitor the disk array. An example of An SNMP management application is Hewlett-Packard¡¦s Open View. The firmware-embedded SNMP agent can be used to augment the RAID controller if you are already running an SNMP management application at your site.
S.M.A.R.T
Self-Monitoring Analysis and Reporting Technology is an ¡§early warning system¡¨ that the disk manufacturers incorporate logic into their drives. AXUS S.M.A.R.T. function detects and reports status of hard drives thus enriches the data availability.
Easy Management
Users can easily configure or maintain the RAID via the RS232 port, LCD control panel, or Web browser-based manager. RAID array configuration, system hardware monitoring, error alert can be all done at your finger tips.
