Demartek Validates Nimbus Data’s Industry-leading Flash Memory Performance and VMware Integration

Industry-leading Multiprotocol Storage Performance

The Demartek SSD Deployment Guide confirms that Nimbus’ award winning S-Class flash memory systems deliver outstanding performance across a broad range of protocols, including 10 Gigabit Ethernet, Fibre Channel and Infiniband. Demartek ran IOzone and TIObench, two prominent benchmark tools, against the Nimbus S-Class, performing individual tests at varying block sizes and combined tests over multiple protocols at the same time. In IOzone, just one Nimbus S-Class 2.5 TB system utilizing a dual-port QDR Infiniband connection delivered near line-rate 7.6 GBps performance on reads and over 2 GBps on parity-protected (RAID 5/6) writes.

Purpose-built Non-blocking Architecture Fuels Record Performance

The uncached performance results demonstrate the inherent advantages of Nimbus’ proprietary non-blocking controller architecture. Unlike off-the-shelf storage enclosures and servers, Nimbus’ approach eliminates expanders and oversubscription that hinder legacy storage arrays modified with flash or all-flash arrays based on commodity servers. TIObench results, which take advantage of caching, show even higher performance, with multithreaded read operations bursting to over 20 GBps, an astonishing accomplishment for a single Nimbus S-Class system. This industry-leading speed sets a new bar for price/performance and energy/performance unmatched by legacy 15K RPM or competing flash arrays.

Full VMware Storage API (VAAI) Integration

Demartek also validated Nimbus’ support of VMware’s Storage Hardware Acceleration APIs, including Full Copy, Block Zeroing, and Hardware-Assisted Locking. These storage array-specific features reduce the CPU and memory utilization of VMware hosts, increasing VM consolidation per host and reducing administration and licensing costs. Full Copy, also called copy offload, enables Nimbus systems to make full copies of data within the storage system without having the host read and write the data, accelerating operations like vMotion and reducing the network load when cloning and provisioning VMs from templates. Block Zeroing, also called write same, enables the Nimbus system to zero out a large number of blocks to provide newly allocated storage, increasing effective storage utilization and simplifying administration. Hardware-assisted locking, also called atomic test and set (ATS), enables the Nimbus systems to support sector-level, rather than LUN-level locking, enabling larger LUN sizes while improving storage performance, increasing VM consolidation, and simplifying administration.

Automatic SSD Enablement

Demartek also validated Nimbus’ support of Automatic SSD Enablement, a new feature in vSphere 5 that leverages the low latency of flash technology to improve VMware operations. Benefits include the ability to utilize Nimbus-based datastores as swap space and host cache for improved system performance. By automatically appearing as an "SSD Type" device, Nimbus datastores do not require manual SSD tagging, simplifying out-of-the-box administration. Nimbus is the only flash memory system in Demartek’s SSD Deployment Guide shown to support these capabilities.
