Violin Memory

Violin Memory provides the world's fastest and most scalable memory appliances that can dramatically accelerate large dataset applications demanding very high IOPS or low latency. Unlike other SSDs, the same Violin 1010 memory appliance supports DRAM or SLC NAND Flash with other memory types planned for the future. System architect choose Violin because:

It's Greener: With support for 4,000GB of Flash or 500GB of DRAM in a 2U appliance, the Violin 1010 memory appliances provide over 50% power and space savings.

It's Faster: With 1 Million IOPS (DRAM) on a single Linux Host and 100K Sustained Write IOPS (Flash), the Violin 1010 is significantly faster than other processor-based SSDs. The hardware-based data path and the RAID algorithms provide the industry's lowest latencies.

It's Better Value: The Violin 1010 provides hot-swappable Flash system with RAID at a much lower cost per useable GByte than other performance Flash SSD-based systems. Violin is making Flash cost-competitive with performance HDD storage systems, but with a ten-fold performance improvement.

Violin - recent milestones from SSD market history

In August 2007 - Violin Memory launched the world's fastest 2U SSD - the Violin 1010.

In August 2008 - Violin Memory said it had delivered 1 million IOPS on a single interface port (a world record) using the latest version of its RAM based Violin 1010 memory appliance.

In November 2008 - Violin Memory announced availability of a new model - a fast 4TB SLC flash SSD in a 2U rackmount. Its patent pending non blocking architecture delivers the best ratio of flash R/W IOPS in the industry - over 200K random Read IOPS and 100K random Write IOPS (4K block). Interface options include:- PCIe, Fibre Channel and Ethernet.

In September 2009 - Violin Memory announced that Donald Basile has been named CEO. Dr. Basile (with over 20 years of leadership experience) had recently served as the CEO of Fusion-io.

In March 2010 - FalconStor announced technical and VAR channel support for Violin Memory's 2U rackmount FC flash SSD - the Violin 1010 . Although the headline specs of this very fast flash SSD are substantially the same as when it was launched in November 2008 the 2 important things which have changed are:-
  • the availability of SSD ASAP-like features implemented by FalconStor's SafeCache and HotZone software.

We have hundreds of SSD articles on StorageSearch.com
Here, below, are some examples.
  • SSD Market History - lists product and technology milestones in the 30 years of the SSD market upto the end of 2009.
  • RAM Cache Ratios in flash SSDs - it's important to know the underlying RAM cache architecture - even if you're happy with the R/W and IOPS performance.
  • 2010 - 1st Fizz in the SSD Bubble? - even the dogs in the street know this is going to be a multibillion dollar market. Greed will play as big a part as technology in shaping the SSD year ahead.
  • the pros and cons of using SSD ASAPs - auto tuning SSD appliances are a new category of SSD which entered the market in the 2nd half of 2009 to accelerate servers without needing human tune-ups. How can you tell if they are right for you? And how well do they work?
  • the Problem with Write IOPS - in flash SSDs - long established as a useful performance modeling metric - this article explains why some specs are exaggerated when applied to flash SSDs - or predict the wrong results for many common applications.
