HP 3PAR StoreServ 7450

HP's 3PAR StoreServ platform wasn't built for flash, but the vendor has tailored its thin technologies to develop an all-flash version of its 7450 array.

Gold winner in the Storage magazine/ 2014 Products of the Year Storage Systems: All-Flash Systems category.

Unlike many traditional hard disk drive storage arrays, Hewlett-Packard's well-respected 3PAR platform made a strong transition into all-flash.

The vendor designed the HP 3PAR StoreServ 7450 as its all-flash system in 2013, and in 2014 added innovative features to improve price and performance. On the cost front, Hewlett-Packard (HP) added 480 GB and 1.92 TB commercial multi-level cell (cMLC) solid-state drives (SSDs) that can reduce the price of flash to $2 per usable gigabyte with new data reduction features.

HP's all-flash array also capitalized on the thin storage technologies that 3PAR pioneered. Other 2014 additions to HP's 7450 all-flash system included thin deduplication with Express Indexing and Thin Clones. These were upgrades made to the 3PAR Operating System.

HP's hardware-assisted thin dedupe delivers inline, block-level data reduction. It's powered by the same 3PAR ASIC used for thin provisioning, which offloads CPU cycles to avoid adding latency.

Thin Clones software provides host-assisted deduplication for non-duplicative virtual machine clones with Microsoft Hyper-V and VMware ESXi to avoid increasing capacity consumption.

HP's Adaptive Sparing feature reduces capacity reserved for SSD wear management, which the vendor claims increases solid-state drive endurance and usable capacity per drive up to 20%.

The vendor says the HP 3PAR StoreServ 7450 can perform at more than 900,000 IOPS at less than 0.7 milliseconds latency.

One judge praised the 7450 for "very good performance, latency and consistency while maintaining 100% of 3PAR architecture and best-of-breed data services. This is how it should be done [for all-flash arrays]."

Another added, "3PAR was not designed with SSDs in mind, but HP has done a good job adapting the storage system," and noted that the cMLC drives are unique and innovative.

Pricing for the 3PAR StoreServ 7450 all-flash system starts at $65,000 for a two-node set-up with eight 480 GB SSDs, four built-in Fibre Channel ports and HP 3PAR Thin Suite. The 1.92 TB cMLC drives start at $14,315 per drive. HP offers a five-year warranty on flash drives and guarantees six-nines of data availability with a four-node 7450 array.
