Here's an article written by or about Dolphin

Integrating Solid State Storage in a PCI Express Clustering Interconnect (pdf)

Tim Miller says he chose this article because "Using PCIe SSDs as Direct Attached Storage (DAS) is a hot topic these days. This paper describes extending the benefits "outside the box" to e-PCIe SSD (external) by detailing a number of new e-PCIe SSD usage models using Dolphin's StorExpress. This includes simple DAS, with virtualization and HA support for up to 2TB for slot limited rack or blade servers to the ability for integration in PCIe cluster environments for multi-server connectivity and eventually shared storage creating 'networked' DAS - the flexibility of SAN, simplicity of DAS and the performance of SSD."

Design Tradeoffs for SSD Performance - written by Nitin Agrawal (University of Wisconsin) and Vijayan Prabhakaran, Ted Wobber, John D. Davis, Mark Manasse and Rina Panigrahy at Microsoft Research presented at the annual USENIX conference.

Tim Miller says "This paper is a useful primer on technical trade-offs for SSD performance appropriate for non-engineers who want to have a foundation of knowledge."

"The 're-debate' of SAN vs. DAS takes on a new dimension with PCIe SSD and now e-PCIe SSD - I thought a couple recent blogs and articles were interesting"

Editor's comments from SSD market history.

Dolphin entered the SSD market in March 2009 - with the launch of its - StorExpress a rackmount SLC flash SSD with upto 960GB capacity.

The PCIe connected SSD has R/W throughput upto 2,700MB/s and 50 microsecond access latency. Dolphin quotes a figure of 270,000 IOPS but the initial datasheet doesn't break out IOPS figures for reads and writes. The StorExpress can be located upto 10m from the host bus using copper cable and 300m with optical fibre.

In many ways Dolphin's SSD system bears more similarity to products from NextIO (which are also PCIe chassis populated by PCIe SSD cards) rather than to proprietary SSD rackmounts - such as those from Violin Memory (which launched the industry's first commercial high-end PCIe SSD rackmount in 2007).
