AccuRAID iSCSI and Fibre Channel SAN - Hardware Features Highlights
The AccuRAID iSCSI and FC SAN 3 and 5 series is the newest generation of Dual-Active (Active-Active) SAN systems with high performance. It's simple, secure, scalable, and affordable for enterprises. It brings enterprise-level features such as thin provisioning, SSD read and write cache, auto tiering, and snapshot to the SMBs. The AccuRAID iSCSI and FC SAN 3 and 5 products are designed to be an ideal solution to the applications of mission critical data centers, high performance computing, virtualization integration, or media and entertainment environments.
Dual Active Design
The AccuRAID iSCSI and FC SAN 1 and 5 series features a Dual-Active controller architecture. Both controllers concurrently provide storage services in real time. Active-Active architecture doubles the available host bandwidth and cache-hit ratio which ensures there is no wasted resource in the system. If one controller fails, the other controller can transparently seamlessly take over all storage services. In addition to storage services, management services can be transparently passed to the secondary controller.
Design for All Flash Storage - 2U 26 bay SFF
|
AR226T3R and AR226T5R (2.5” 2U 26-bay) is the industry’s first high-density all flash/low power SAN storage. It has accelerated performance, consolidated space, and two more storage bays (up to 8% more capacity) than the popular 2U 24-bay products available on the market. This can further lower the cost per TB, minimize IT rack space, and generate a smaller and greener footprint.

High Availability with No Single Point-of-Failure
AccuRAID iSCSI and FC SAN series is a proven high-availability SAN storage system. All of the critical components in the series are hot pluggable and designed with full redundancy. Additionally, dual-active controller design and automatic failover/failback mechanism and cache mirroring through NTB (Non-Transparent Bridge) bus to achieve Active-Active HA functionality allows the AccuRAID iSCSI and FC SAN series to withstand multiple component failures and achieve 99.999% availability.
Latest 12Gb SAS 3.0 Controller
|
12Gb SAS 3.0 is the latest and fastest drive interface available. It doubles the data transfer rate of SAS 2.0 (6Gb), while remaining backward compatible with 6Gb SAS 2.0 drives. The benefit is that you have the flexibility to purchase less expensive 6Gb SAS drives for initial installation or leverage investment of your existing 6Gb SAS drives and have a peace of mind knowing you can migrate to 12Gb SAS 3.0 by purchasing only new drives.

Multipath Storage Access
MPIO (Multi Path Input Output) is a fault-tolerance and performance enhancement technique which allows the use of more than one path to the volume from the same host server. MPIO is supported in both iSCSI and Fibre Channel protocols.
High Density, Flexibilty and Scalability - 2.6PB Scale-up Solution
AccuRAID iSCSI Enterprise SAN solution provides a massive scale-up capability by connecting our AccuSTOR expansion enclosures. It can support up to an impressive 286 disk drives or up to 2.6PB of raw storage space when using 10TB NL-SAS drives.
The expansion AccuSTOR series is available in 4U LFF 24-bay (AS424TX12R), 3U 16-bay (AS316TX12R), 2U 12-bay (AS212TX12R), and the world’s first 2U SFF 26-bay (AS226TX12R). These can support up to ten expansion enclosures. For ultimate flexibility, there is no restriction on mixing different form factors of expansion enclosures together. Users can choose different form factors of expansion enclosures in accordance to their needs and budget.

Modular I/O Ports for iSCSI SAN and Fibre Channel SAN
Each SAN controller has two host card slots that can be configured as iSCSI SAN, Fibre Channel, or a mix of both. There are various types of optional host cards available to match your specific need, including 16Gb Fibre Channel, 10GbE iSCSI in SFP+ modules or 10GBase-T form factor. 10GBase-T is fully backward compatible with existing Gigabyte Ethernet networking structures. You can choose the appropriate host card for your initial requirement and as your business grows you can add extra host cards to enhance system connectivity.
Direct Connection or Connecting with 10G or FC Networking Swithes
AccuRAID Enterprise SAN Solutions can support up to 20 ports of 10GbE iSCSI or 8 ports of 16Gb FC connectivity. Both 10GbE iSCSI with SFP+ interface and 10GBASE-T interface can coexist and deliver concurrent data services and maximize uptime. Utilizing these numerous ports, you can cost-effectively connect multiple host servers directly to the AccuRAID units without using an FC switch or Ethernet switch.

Cache-to-Flash Memory Protection Technology
In the event of power loss, the I/O cache data stored in volatile memory will be lost. This can cause data inconsistencies, especially in database applications. The AccuRAID Enterprise SAN series can provide an optional Cache-to-Flash memory protection function that will safely transfer the memory cache data to a non-volatile flash device for permanent preservation. The optional Cache-to-Flash module comes with an M.2 flash module and either a BBM (Battery Backup Module) or an SCM (Super Capacitor Module).
*The BBM can protect all memory capacity. SCM protect up to 16GB memory per controller. If your system memory is higher than 16GB, please select BBM solution.
*The BBM can protect all memory capacity. SCM protect up to 16GB memory per controller. If your system memory is higher than 16GB, please select BBM solution.

Wake-on-SAS TechnologyWake-on-SAS technology allows you to remotely power on/off all cascaded SAS JBOD expansion enclosures by using proprietary SAS cables. You can power on the XCubeSAN system remotely using the Wake-on-LAN feature. The AccuRAID Enterprise SAN system can work with any available Wake-on-LAN freeware and shareware. Wake-on-SAS ensures that expansion enclosures will not run idle, consuming electricity after the SAN storage system is shut down for maintenance or other purposes. Wake-on-SAS helps avoid unnecessary electricity waste by allowing your devices to be on only when it is necessary. Wake-on-SAS also benefits when when you turn on the SAN, the expansion enclosures will wake automatically, so that there is no need to worry about degrading a volume if you forget to turn them on first.

Auto Disk Spin-downWhen the disk drives have not been accessed or are not scheduled to be accessed for a set time defined by you, the auto disk spin down functionality will kick in, and will power down the whole storage pool into a hibernation state. This gives you the freedom to optimize the energy usage of the SAN storage system. Disk spin-down can save 60% to 70% power in low use scenarios such as backups. When the system detects read/write requests coming in, it will issue a wake command. This takes a few seconds to spin up all the disk drives in the storage pool to resume all data services. The performance penalty can be off-set with SSD cache, however.
