Kove has announced the world’s first Terabyte Memory Disk in conjunction with Mellanox Technologies and R Systems. The Kove Xpress Disk (XPD), in combination with Mellanox’s ConnectX-240Gb/s InfiniBand, has achieved more than 20 GigaBytes per second of sustained data bandwidth for random reads and writes.

These results were achieved using a single Kove XPD Gen2 storage appliance equipped with six Mellanox ConnectX-2 40Gb/s InfiniBand ports, serving SRP (SCSI RDMA Protocol) storage via an InfiniBand fabric to an 11-node cluster. The equipment used during the testing process was provided by R Systems.

The Kove XPD is the world’s fastest storage device in a 4U chassis, providing continuous, sustained I/O for any duration of time. The record-setting performance will not degrade under load or over time, and allows organizations to drastically reduce I/O loads and remove storage bottlenecks.

“The next generation Kove Xpress Memory Disk is a continuation of our leadership in high performance storage. The XPD Gen2 provides uncompressed performance for any type of I/O with no loss of performance over time,” states John Overton, Kove CEO.

“We are pleased to support Kove in building a world-leading InfiniBand-based storage solution,” said Gilad Shainer, senior director, HPC and Technical Computing, at Mellanox Technologies. “By taking advantage of InfiniBand's inherent efficiencies and Mellanox's advanced offloading and RDMA technology, Kove is able to demonstrate storage throughput capabilities that can help eliminate I/O bottlenecks for next-generation HPC and enterprise data centers.”

Kove technology has an immediate and demonstrable advantage for most systems. “We employed Kove Xpress Disk to address an I/O bottleneck that caused poor response in metadata transactions,” explains Ramon Williamson, Storage Systems Engineer at Purdue University. “A response of over four hours was reduced to seven minutes using the Kove Xpress Disk, with similar performance seen from day one for all I/O requests to the system. I, and more importantly, my users, are thrilled with the amazing performance achieved. Outstanding!”
