Kove® XPD

The Kove® XPD® L3 I/O appliance provides the highest performance InfiniBand and Fibre Channel persistent I/O available, holding world records for bandwidth, latency, and IOPS. Our published latency includes full round-trip from and to application.

The Kove® XPD® L3 uses DRAM to deliver deterministic performance across all I/O patterns, whether reads or writes, small or large blocks, sequential, random, burst or sustained access, one minute or ten year duration, 10% or 100% full, or any combination thereof. Utilization does not degrade XPD® performance and media never wears out.

About Kove® XPD

The Kove® XPD® L3 I/O appliance provides the highest performance InfiniBand and Fibre Channel persistent I/O available, holding world records for bandwidth, latency, and IOPS. XPD® L3 uses DRAM to deliver deterministic performance across all I/O patterns, whether reads or writes, small or large blocks, sequential, random, burst or sustained access, one minute or ten year duration, 10% or 100% full, or any combination thereof.

Applications using Kove® XPD® L3’s don’t worry about media wearing down or out, or performance changing because of load or occupancy. With determinacy and concurrency literally 100s of times better than Flash, apps can scale-out processing like no other product in the world. This means fewer CPUs, less energy, better output. For example, 4 servers using 4 XPDs have demonstrated 65 terabytes of database operations per hour at more than 800 million database operations per second. I/O is no longer the bottleneck in XPD installations.

Performance

The Kove® XPD® L3i 1U appliance delivers performance I/O across the spectrum: 27+ GB/sec read/write bandwidth (at 12 µs latency and 100 ns variance) and 43+ million IOPS (at 3.0 µs latency and 100 ns variance). Or ingest (write) at 18 GB/sec or 1 TB/min (at 11 µs latency and 100 ns variance). All performance is sustained, deterministic, and linearly scalable: XPD® L3i’s do just as well in customer testing as in workhorse performance lasting years at a time under load. And performance doesn’t change because of age, usage, load, profile, capacity, or any other factor.

Some vendors “tune” product performance for 4K blocks, or optimize for access pattern, and then perform poorly when using 512-byte or 1MB blocks, or sequential or random I/O. Kove® XPD® L3’s deliver consistent performance across the I/O spectrum without qualification. They just work — faster. Apps just work — better.

This is the value of deterministic and concurrent I/O, the next new. Run faster, longer, better, reduce core count, drop licensing fees, reduce energy footprint, save more money, make more money. Let design drive profitability.

Features

XPD® L3’s are InfiniBand and Fibre Channel direct and mesh attachable to accommodate scalable, high performance I/O needs. All speeds are supported: SDR, DDR, QDR, FDR for InfiniBand, and 2-8 Gbps for Fibre Channel.

Kove® XPD® L3 I/O appliances monitor overall system health, and tracks 100s of system components and monitorables. The device can self-heal most problems before they are ever noticed, and report health status via SNMP, syslog, or HTTP.

The XPD® L3 uses an uninterruptable-power supply (UPS) to protect against down-time. Utility-company power spikes or outages do not threaten data integrity.

Mirroring:
ECC plus SDDC (standard), rank sparing and RAM mirroring (optional)

Prevent DIMM rank failure from affecting data integrity. Device copies failing rank to spare and then disables failed rank.

Device maintains mirrored copy of memory image. Device fails over to mirrored copy if an uncorrectable error occurs.
