Competitive Selling Guide: EMC VNX Series vs. HP/3PAR
HP/3PAR Overview
HP’s go-to-market strategy is its claim to have a more modern hardware/software architecture that scales out and has embedded ease of use to solve “Big Data,” cloud, and “instant-on business” requirements. HP positions EMC’s VNX series as a repackaging exercise that is only “unified” at the Unisphere GUI with two aging software architectures running different O/S and associated software. HP regards the VNXe series as a totally different architecture representing EMC’s true “unified” storage future. HP’s latest announcement claims a better choice is “Converged Storage” and states that unified storage had its place but is not the direction HP is headed. Store360 is the new HP architecture that converges the IBRIX, LeftHand, 3PAR, and StoreOnce acquisitions into one offering. Major points HP uses against the EMC VNX series are: VNX series is really two architectures unified only by a brand; EMC continues its monolithic approach to storage that is disconnected from the rest of the infrastructure and merely connects two legacy architectures to build a more unified silo. HP’s autonomic tiering is more flexible and supports any RAID type (in a single storage pool). 3PAR has the best SPC benchmark results at the lowest price per IOP of any array tested; EMC does not publish any public benchmark results. VNX series allows for in-family upgrades and scales better than 3PAR to meet customers’ growing needs.

Note: Also consider positioning the VNX gateways when adding NAS to existing EMC SAN environments.

How does 3PAR offer NAS access? It requires an IBRIX X9320 gateway, adding significant cost and complexity. EMC has integrated block and file within the same platform managed by the same Unisphere interface. EMC VNX publicly announced its SPEC results.

Positioning VNX Series Models Against HP/3PAR — A Mapping Summary
Why VNX Series over HP/3PAR
The VNX series delivers industry-leading innovation and enterprise capabilities for file, block, and object storage—simply, efficiently, and powerfully. VNX scales better than HP/3PAR and is simpler to manage. One modular-based unified platform with one unified management application. For Flash-optimized storage to boost performance and minimize costs, st take advantage of a FLASH 1 strategy with Fully Automated Storage Tiering for Virtual Pools (FAST VP) and FAST Cache. Only EMC can tier within the platform (VNX and FAST VP) and to the cloud/archive (VNX and the Cloud Tiering Appliance)
Questions To Ask HP/3PAR
HP claims write cache persistency in the case of a node failure. How does HP achieve this on the F200 or on any system configured with just two nodes? 3PAR write cache persistency requires at least four nodes (nodes sold in pairs); customer pays twice for the controllers as VNX supports write cache persistency even when an SP fails. This significantly increases the entry-point cost for HP. VNX processors are “oversized” to offer the best possible performance with little to no impact even if a controller fails. How do 3PAR arrays scale within the family? They don’t. An F200 t o a F400 is a forklift upgrade, as in the T family (T400 to T800). With the VNX series, customers can start small with the VNX5300 and move up the stack as their infrastructure requirements grow.
