  • Texas Memory Systems Delivers Record 5-Million IOPS Flash-based SSD System

    Texas Memory Systems launches the RamSan-6200 SSD System that offers up to 100 terabytes of Flash-based storage in a 40U rack configuration that can sustain a record 5 million input/outputs per second (IOPS) with 60 gigabytes per second throughput while using a little over 6 kilowatts of power.

    To achieve the equivalent level of performance with hard disk-based storage arrays would require several thousand of the 15,000 RPM hard disk drives.

    The RamSan-6200 is a scaled up system that combines twenty RamSan-620 solid state disks in a single datacenter rack and uses Texas Memory Systems’ TeraWatch software to provide unified management and monitoring from a single GUI console. The system utilizes enterprise grade Single Level Cell (SLC) Flash as well as multiple levels of RAID and advanced Flash management algorithms.

    A single RamSan-620 unit provides 5TB of Single Level Cell (SLC) Flash with 250,000 sustained IOPS for random reads and random writes. Each RamSan-620 unit can support 2 to 8 Fibre Channel or up to 4 InfiniBand links.

    At the chip level, TMS uses only SLC Flash memory. Each Flash chip incorporates an Error Checking and Correction (ECC) data field within the chip to check and correct single-bit errors.

    At the board level, each set of Flash chips is organized as a board-level RAID, thereby eliminating any single chip failure from corrupting data.

    At the system level, the RamSan-620 allows to designate one of the cards inside the system as an active-spare that works hand-in-hand with the chip level RAID on each of our boards. If one of the cards experiences a failure that degrades its RAID protection, the system will immediately migrate the data on that card to the hot-spare to return to a fully redundant state.

  • Adaptec Introduces Greener More Efficient RAID Controllers


    Adaptec has announced the availability of its Series 5Z Unified Serial (SATA/SAS) RAID controller family.

    The company said these high-performance controllers integrate an industry first – a flash-based Zero-Maintenance Cache Protection module that provides data center managers with a single controller solution for data protection in the event of both power loss and drive failure.

    Designed to replace a current generation of Lithium Ion battery-based cache back-up devices, the Adaptec RAID Series 5Z is an integrated solid state solution designed to "significantly reduce" annual data center operating costs and environmental impact.

    The controllers offer an integrated, maintenance-free design, eliminating the need to monitor battery charge levels or shut down servers for battery replacement.

    Scott Cleland, director of marketing, Adaptec, said that as enterprise storage demands skyrocket, there is an enormous need for feature-rich, maintenance-free data storage I/O solutions that work to lower overall IT costs and provide significant environmental advantages.

    "For both SATA and SAS drives, the Adaptec Series 5Z family not only delivers the performance, scalability and power efficiency that our customers demand, but with Zero-Maintenance Cache Protection, it offers a simple, maintenance-free solution that provides a critical layer of data protection that is often overlooked," he said.

    All three Adaptec Series 5Z controllers are available now priced at the following MSRPs: Adaptec RAID 5405Z (USD $785), Adaptec RAID 5805Z (USD $965), Adaptec RAID 5445Z (USD $1,045).

  • BitGravity Offers 1080p HD Live Video Streaming







    BitGravity announced today that it is launching a live digital video service that will allow users to stream Flash-based HD video over the Internet.

    The BG Live HD service can stream live events in 1080p or 720p resolution and doesn’t require a viewing client to be downloaded.

    The content delivery network (CDN) provider, making the announcement at DEMO 2009, said the new service was the first affordable, true HD, online streaming service for live events in 1080p or 720p resolution.

    Perry Wu, co-founder and CEO of BitGravity, said the notion of HD live broadcasting over the Internet is not earth shattering.
    However, he said doing it in a way that enables wide adoption is.

    "Technology is not meaningful if we only deliver four out of five requirements that customers demand," he said.

    "TV-quality 720p and 1080p HD with only a few seconds delay off live, no client download, simple set-up, scalability, and affordability are the table stakes for being a player in this space."

    Last October, BitGravity announced the release of an application programming interface (API), capable of supporting cutting-edge interactive video applications.

    Based in Burlingame, California, the company launched a standard-definition version of the live online streaming service at last year’s DEMO event.

    Since then it has live streamed events such as the Democratic and Republican national conventions and President Barack Obama’s inauguration.

    Wu said BG Live HD, provides TV-quality video with just a few seconds of delay.

    He said the service has low hardware start-up costs.

    The HD H.264 live streaming software will initially be offered at no price premium over SD H.264 delivery.

    To stream live with an HD camera and Internet connection, BitGravity requires only an Apple Mac Pro loaded with BitGravity transcoding software, a PCI expansion card, and an HDMI or HDSDI source connected to BitGravity’s network.

    The new service streams data at a rate of 1.5- 2 megabits per second, which most cable modems and DSL lines can handle.
    BG Live HD will be generally available in April.

  • Gizmo5 Introduces Browser-Based VoIP Application


    Gizmo5 has launched a web-based VoIP app that allows users to call 800 numbers and SIP addresses for free.

    GizmoCall is Flash-based, so it only requires a browser to use the service rather than having to download a software client.

    Users go to the Web site, sign up for a username and password, and start making calls.

    The service can also accept inbound calls to the login user name, so long as the app is running in a window or browser tab.

    You can also drop one line onto a webpage to do inbound calling from GizmoCall.

    To make outbound calls, users require a GizmoCall account.

    The Adobe Flash client should work on Mac, Windows and Linux platforms.
