Marvell has unleashed a turnkey enterprise-class PCIe SSD caching solution with built-in SSD modules, extending the firm's DragonFly NVCACHE and NVRAM adapter product offerings. Geared for large-scale Internet and cloud computing datacenters, the DragonFly NVDRIVE claims to significantly scale both bare metal and virtualized server applications including Web servers, OLTP and analytic databases, as well as NoSQL and big data distributed applications, said Marvell.

The DragonFly NVDRIVE is powered by Marvell's storage SoC technology and seamlessly merges large capacity 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 disc-based solutions, Marvell indicated. Additionally, automated caching removes the guesswork, maintenance and high capital costs required by manual data tiering approaches. Unique to the industry, 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.

The Dragonfly NVDRIVE features up to 1.5TB of useable SSD capacity with integrated non-volatile DRAM cache and highly predictable performance across mixed write/read workloads. In addition, it has cache mode sustained performance exceeds 200,000 4K random IOPS, 3GB/s throughput and sub-10us average latency. Also, the solution boasts robust data protection, including RAID and HA peer-to-peer synchronous mirroring software.

Marvell stated that the DragonFly NVDRIVE offers rich command line interface (CLI) and cache policies for granular file/block object level configurations. It also has application-transparent OS filter driver that supports all major protocols—SCSI, iSCSI, NFS, FCoE and FCP. Likewise, it boasts hypervisor integration that enables virtual machine migration, HA, snapshots, clones and more. It also flaunts 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. Pricing starts at a manufacturer's suggested retail price of $2,995.
