Kove® XPD™ L2 storage delivers the lowest latency, highest IOPS, and highest bandwidth I/O in the world. Our reported performance includes full round-trip I/O.

• 2 Terabyte Capacity

  The Kove® XPD™ L2 is the world’s first 2 terabyte memory disk. All capacity is usable, and performance is uniform across I/O
  patterns.

• 28.5 GB/sec Bandwidth

  Bandwidth can be maintained continuously and can be sustained across any duration, even years.

• 11.7 Million IOPS

  Sustained and random, not sequential. These are not burst numbers.

• 5 µs Read and 5 µs Write Response Time

  Consistent and sustainable for any duration.

• Instant Copy

  Instant copies are self-contained in the device. They are among the fastest in the world.

• Performance Unaffected By Occupancy

  Kove® XPD™ L2 performance remains steady whether it’s 10% full or 95% full. Performance doesn’t change as the occupancy changes.

• Performance Unaffected By Reads, Writes, or Mixed AccessPatterns

  The Kove® XPD™ L2 performs similarly well, whether reading, writing, or doing both. The access pattern never degrades performance meaningfully.

• Uniform Performance Across Random and Sequential Access

  Kove® XPD™ L2 performs similarly well whether or not I/O access is random or sequential.

• Uniform Performance Across Small or Large Blocks

  The Kove® XPD™ L2 performs consistently well regardless of block size. Some media “tune” performance for 4K blocks, but then perform badly when using 512 byte blocks, or 1 MB blocks. The XPD™ L2 performs uniformly well across all block sizes.

• Uniform Performance Across Time

  Kove® XPD™ L2 performance doesn’t wear down and the media doesn’t wear out. It will run as well out of the box as it will years later. It will not require media swap-outs.

• System Health

  The Kove® XPD™ L2 tracks health components for more than 120 monitorables.

• Self-Healing

  The Kove® XPD™ L2 self-heals for most problems that can occur, eliminating problems before they ever are noticed. Additionally, the XPD™ L2 constantly monitors storage health, and can report status via SNMP, Syslog, or HTTP down to the second.

• Uninterruptible Power Supply (UPS)

  The Kove® XPD™ L2 comes standard with a UPS to protect against downtime. You’ll never be bothered by another utility company power spike. If a power outage does occur, the XPD™ L2 will gracefully shut down only if or when necessary to protect the data. When you bring the XPD™ L2 back online after an outage, data will be where it should be.

• 2 Terabyte DRAM Capacity

  The Kove® XPD™ L2 uses DRAM, not flash, and is the first DRAM memory disk to reach 2 TB per unit. It is mesh-attachable to accommodate larger storage needs.

• InfiniBand & Fibre Channel

  The Kove® XPD™ L2 supports either InfiniBand or Fibre Channel interconnects. All speeds are supported: SDR, DDR, and QDR for InfiniBand, and 2,4,8 gbps for Fibre Channel.

• Performance

  The Kove® XPD™ L2 provides up to 28.5 GB/sec bandwidth, the highest continuous, sustainable performance in a 4U enclosure.

• Support

  All Kove® products include comprehensive worldwide support ranging from next day to 24x7x365 two hour on-site service.
