Dual-Active HA Architecture

The COTT-JSS202-S24RB is a 2U 24-bay 2.5” drives dual-active storage product with two controller modules interconnected via X8 PCIe 3.0 NT for cache mirroring. The entire system is based on a cable-less, modular design to benefit the maintenance and serviceability.


Powerful Data Processing Capability

The system is based on Intel® X86 architecture with Intel® Grantley-EP platform. Each controller comes with Intel® latest generation LGA2011 E5-2600 V3 / V4 CPU and supports up to 8 DDR4 DIMMs, and expandable to maximum 1024GB memory capacity. The end-to-end 12Gb solution maximizes system I / O performance.


Versatile I/O Interface 

Each controller has four iSCSI (based on Intel® i350) host interfaces, one Gigabit Ethernet management network port (shared with IPMI) and one console interface (RJ45, compatible with CISCO standard). Optional two 10Gb iSCSI or four 16Gb FC / 8Gb FCs per controller

And each controller comes standard with two 12Gb SFF-8644 Mini-SAS HD for daisy-chained drive expansion interface.


Flexible SAS Mezzanine Card Options

The motherboard supports the COTT® own Mezzanine Card design, supports two kinds of SAS controller by LSI 3008 and PMC8068, customers can choose either one according to their own needs.


Complete Data Protection

The system is designed 1+1 BBU redundant battery backup system to prevent from the AC power-off accident with data loss.


Energy Saving for Green

The power system equips platinum 1+1 redundant power supply, intelligent fan speed control is based on PID closed-loop control, power capped NM technology, and DC-DC switching power supply with up to 94% power efficiency, which greatly reduces system power consumption.
