Marvell Unveils DragonFly NVdrive

Jan 08, 2013 (Close-Up Media via COMTEX) -- Marvell announced the availability of the Marvell DragonFly NVdrive, a turnkey enterprise-class PCIe SSD caching solution with built-in SSD modules that extends the company's DragonFly NVCACHE and NVRAM adapter product offerings first announced last August.

In a release, the Company noted that the DragonFly NVdrive scales both bare metal and virtualized server applications, including Web servers, OLTP and analytic databases, as well as NoSQL and big data distributed applications.

"The NVdrive is a game-changing extension of the popular DragonFly NVRAM and NVCACHE family. It delivers the same unprecedented application acceleration as the existing NVCACHE solution, but now seamlessly integrates with onboard SSD modules for plug-and-play ease of use," said Alan Armstrong, vice president of marketing of Marvell Semiconductor's Storage Business Group. "The innovative application of non-volatile DDR memory, highly optimized caching algorithms, and entry enterprise SSD modules creates a converged solution that is ideally suited for mixed-workload cloud data centers. The NVdrive raises the bar on affordability and performance, and its unique cache automation and consistent write latency capabilities will be sought after by both OEM and cloud computing customers who require predictable performance at reasonable costs." The DragonFly NVdrive is powered by Marvell's storage SoC technology and seamlessly merges non-volatile DRAM with onboard SSD modules to enable up to 100 times higher performance for random read- and write-heavy application workloads as compared to traditional disk-based solutions. Additionally, automated caching removes the guesswork, maintenance and high capital costs required by manual data tiering approaches. DragonFly writeback caching is fully powered by ARM-based storage processors and enables storage administrators to configure granular cache policies at either a file or block level.

Data protection and reliability are ensured via intelligent RAID software and peer-to-peer synchronous mirroring to prevent data loss against any failure server, adapter, SSD module or NAND components. An ultra-thin filter driver residing in Linux or Xen is transparent to applications and supports caching across all storage protocols, including SCSI (local DAS), NFS, iSCSI, FCoE and FCP.

Features include: -Up to 1.5 TB of useable SSD capacity with integrated non-volatile DRAM cache.

-Predictable performance across mixed write/read workloads. Cache mode sustained performance exceeds 200,000 4K random IOPS, 3GBps throughput and sub-10us average latency.

-Enterprise-class embedded write-back cache software. Simple, smart and fully automated.

-Data protection, including RAID and HA peer-to-peer synchronous mirroring software.

-Rich command line interface and cache policies for granular file/block object level configurations.

-Application-transparent OS filter driver supports SCSI, iSCSI, NFS, FCoE and FCP.

-Hypervisor integration enables virtual machine migration, HA, snapshots, clones and more.

-Fully integrated DragonFly Manager for GUI-based administration and performance monitoring.

The Marvell DragonFly NVdrive will be sampling later in Q1 with OEM and cloud computing customers. DragonFly NVdrive is offered at 750GB and 1.5TB capacity points.

Marvell is a provider of storage, communications and consumer silicon solutions.
