Intel® Xeon® E5 dual-controller for nearly zero downtime high-availability
The ES1640dc v2 is powered by two Intel® Xeon® E5-2400 v2 processors and features dual active-active controller architecture, ensuring businesses with nearly zero downtime high availability as the standby controller can quickly take over if one controller breaks down. The ES1640dc v2 connects to the JBOD enclosure (EJ1600 v2) via the dual path mini-SAS design to sustain continuous operations even if an external JBOD cable is disconnected. Designed around redundancy, the ES1640dc v2 is the best realization of reliable enterprise storage for uninterrupted mission-critical enterprise tasks and productivity.
Dual controller NAS: high reliability and high availability
“Reliability” is the primary priority for mission critical business applications. The ES1640dc v2 adopts dual active-active controllers to provide the most reliable base for business IT storage.
Dual active-active controller
If one controller fails, the other one will immediately take over to provide high availability with the least downtime.
Built-in 4 x 10GbE SFP+ ports
Intel® XL710 network card provides four 10GbE SFP+ ports* to fulfill various iSCSI/NFS/CIFS network data transmission requirements.
*Due to a current driver issue, QES 1.1.3 only supports 2.5 Gb/s for each Ethernet port. Support for 10 Gb/s will be available in a future firmware release.
Pre-installed dual-port 10GbE (RJ45) network card
The PCIe slot is pre-installed with a LAN-10G2T-X550 network card that offers two 10GbE RJ45 ports. Users can replace it with a dual-port QSFP+ 40GbE NIC to provide massive data transmission potential and to simplify network cabling.
SAS 12Gb/s hard drive
Dual-controller architecture that supports SAS 12Gb/s and SAS 6Gb/s hard drives / SSDs, providing versatile storage choices for enterprises.
NVRAM w/ Copy-to-Flash
Battery-protected DRAM write to cache data protection and Flash read acceleration provides industry-leading random access performance to benefit virtual machine deployment.
(1) NVRAM dedicated DDR3 memory modules - supports 16GB, power required by C2F is supplied by BBU.
(2) Dual-channel DDR3 system main memory - each channel supports 16GB/32GB, providing up to 32GB/64GB total capacity.
Stores cache data written by DRAM to ensure information is not lost if the system experiences a sudden power failure.
Dual Path Mini-SAS 12Gb/s (EJ1600 v2), 6Gb/s (EJ1600) JBOD architecture
Increases the ES1640dc v2’s potential storage capacity to over 1 PB with expansion enclosures.
Intel® Xeon® E5-2400 v2 series processor
Provides the performance required by software-defined storage and commercial mission-critical applications.
Field-replaceable unit (FRU) applies not only to the controllers but also to the cooling fans, power supplies, and the BBU battery pack for C2F (Copy-To-Flash), providing a cost-effective way to maintain complex systems and to replace defective parts.
NVRAM cache reducing the risks of losing write cache data
To increase random write performance and reliability, the ES1640dc v2 features NVRAM modules (DRAM Write Cache with Copy-to-flash) to protect write data. When data is written into NVRAM, there are dedicated backup battery units to protect writing to the cache, and at the same time the data is replicated to a backup controller, to achieve 100% data integrity. NVRAM-backed write cache in the dual-controller architecture presents high performance, fault-tolerant, and helps reduce flash SSD write amplification.
