Who's who in SSD? - by Zsolt Kerekes, editor - November 28, 2011

Here's the short of it

Kove (a top 20 SSD company) markets the fastest rackmount SSD appliance available in a 4U form factor. If you're researching products in this performance category you should also take a look at Texas Memory Systems, Violin Memory and Fusion-io.

Here's the long version

Kove is 1 of 15 companies in the fastest SSDs list, and 1 of about 20 companies listed in the RAM SSDs directory and it's also in the top 20 SSD companies list. Kove is also listed in these guides too:- FC SAN SSDs and InfiniBand storage and SSDs.

There's a growing realization in the enterprise market that RAM SSDs will be a permanent part of the SSD toolkit in high transaction volume datacenters which have any kind of traditional hierarchical data architecture. And the only reason for buying them is to solve problems which flash SSDs create or can't solve technically because of RAM's superior latency, bandwidth, truly symmetric IOPS, better reliability (and sometimes lower floor price).

Kove's Xpress Disk embodies how fast you can go in an FC SAN / IB connected RAM storage appliance - with 8 microsends latency and nearly 30 gigabytes / s bandwidth.

Who can afford this?

Most of you can't.

But if you're in the financial services industry and want an edge on competitors delivering real-time market data - this is the type of product you can't afford not to look at. Especially as it was recently (Oct 2011) shown to be 12x faster than the previous fastest storage system when performing a Market Snapshot benchmark.

I currently talk to more than 300 makers of SSDs and another 100 or so companies which are closely enmeshed around the SSD ecosphere - which are all profiled here on the mouse site.

I learn about new SSD companies every day, including many in stealth mode. If you're interested in the growing big picture of the SSD market canvass - StorageSearch will help you along the way. Many SSD company CEOs read our site too - and say they value our thought leading SSD content - even when we say something that's not always comfortable to hear. I hope you'll find it it useful too.

Kove mentions in SSD market history

In November 2010 - Kove demonstrated a 4U InfiniBand & FC compatible RAM SSD product line called Xpress Disk - which can sustain 20GB/s throughput via 6x InfiniBand ports.

In June 2011 - Kove announced that its XPD2 4U 2TB RAM SSD had achieved the following performance:- 11.7 Million IOPS in a single addressable space, 28.5GB/s bandwidth, along with round trip latency of 6 microseconds for read and 8 microseconds for writes.

"The next generation Kove Xpress Memory Disk is a continuation of our leadership in high performance storage for those customers who need the absolute fastest storage system available," states John Overton, Kove CEO. "The XPD2 connects directly to storage fabrics via standard Fibre Channel and InfiniBand interconnects, while increasing performance density way beyond any other similar storage alternatives."

In October 2011 - Kove's XPD2 was 12x faster than the previous fastest system - in the Market Snapshot benchmark audited by STAC.

In May 2012 - Kove published some new record latency numbers for its fast RAM SSD - the XPD L2 - which has achieved continuous and sustained 5 microsecond random storage read and write when connected via 40Gb/s InfiniBand adapters from Mellanox .

sharpen your SSD R/W grid latency to 5µS
Editor:- May 9, 2012 - Kove has published some new record latency numbers for its fast RAM SSD - the XPD L2 - which has achieved continuous and sustained 5 microsecond random storage read and write when connected via 40Gb/s InfiniBand adapters from Mellanox .

Kove's system has good R/W symmetry which the company says - is not subject to periodic performance jitter or "periodicity". Even under constantly changing disk utilization, it delivers uniform, predictable, and deterministic performance.

"The Kove XPD L2... allows high performance applications to use storage as a weapon rather than accept it as a handicap," said Kove's CEO, John Overton. "We are pleased to set a new bar height for storage latency."

"In February 2003 - 2 competing SSD companies:- Texas Memory Systems and Imperial Technology simultaneously announced the world's first terabyte class SSD systems. The Tera-RamSan, from TMS, provided 2 million IOPS, a 1024 gigabyte capacity, and 128 2-Gbit Fibre Channel links. It required 2 racks and 5 kilowatts."
