| The B12S RAID enclosure is designed with all the sophisticated high availability features including redundant RAID controllers, a passive backplane, cross-controller 'sync. cache' channels, redundant cooling and power supply modules. Highest performance and spindle density is achieved within the compact design which previously requires 2U or more rack space.
Thanks to the low vibration and reduced airflow requirements of 2.5-inch drives, the B12S runs with higher reliability. As a reminder, the B12F does not compromise on its advanced RAID functionality because of its compact size. The B12S supports RAID levels 0, 1, 3, 5, 6, multi-level logical volumes, and all the renowned firmware functionality as other EonStor series models.
EonPath : The EonPath drivers coordinates with Microsoft MPIO, runs on Solaris and Linux platforms, and provides fault tolerance for multiple data paths and load-balancing algorithms. The EonPath also enables TPGS (Target Port Group Service) for optimizing I/Os through the optimal paths.
Snapshot: Snapshot enables point-in-time backup with high fidelity and minimal impact to ongoing applications. More significant is that the snapshot operation is processed by RAID hardware without load on host CPUs. Snapshot also features dedicated snapshot volumes, automated snapshot scheduler, and comprehensive disk space control.
SANWatch: SANWatch provides all functions necessary to discover, configure, administer, and monitor Infortrend's RAID arrays; be they remote or many. The SANWatch also provides management interfaces for EonPath and Snapshot functions, so that all data protection and high availability features can be accessed through one interface.
Similar to Fibre Channel expansion loops, SAS expander technologies also enable the ease of connections when the need arises for more capacity. All you have to do is to attach the cables and use a flatblade screwdriver to select an enclosure ID by a rotary switch. The SAS WWN addresses will be automatically applied to all the disk drives.
A single-controller RAID can attach to 4 expansion enclosures (60 HDD) via SAS wide links.
A redundant-controller RAID can attach to 3 expansion enclosures. Although the maximum no. of disk drives is reduced to 48, yet fault-tolerant links can be strung between RAID and JBOD enclosures.
With 4.3Gbps physical links combined into a multi-lane wide link, a host or expansion port is capable of a 1200MB/s bandwidth. That is also more abundant than a Fibre Channel dual-loop.
Via SAS multi-lane links over multiple enclosures, the large capacity SATA-II disk drives can be easily implemented for configurations that run on reliable SAS drives and a bulky pool of storage pool made of SATA-II disk drives.
Reliable 2.5" SAS drives can be used for critical and I/O-intensive access, while 3.5" SATA drives can be used for less-critical data, archive, or D2D backup purposes.
In addition to the B12S-J1000 1U enclosures, the B12S RAID series also supports a variety of expansion enclosures in 2U or 3U profiles. For the concern with price/performance allocation, we support SATA-II drives in the 2U and 3U drive enclosures.
