You need a simple, flexible storage solution ideally suited to the demands of your virtual data center. HP StoreVirtual Storage, based on the LeftHand operating system, is a scale-out storage platform designed for the fluctuating needs of your virtualized environment. With inherent enterprise-class storage software functionality and leading virtualization software integration, StoreVirtual can support virtualization growth at all stages. Intuitive, common management simplifies storage administration. And, storage federation enables data mobility across tiers, locations, and between physical and virtual storage. StoreVirtual is also one of the most versatile storage platforms in the market today.

Oracle VM 3. The SSD drives must be installed in bays 8, 9, and 10 located on the far right of the front panel. Under the hood lays a single CPU, a 2. The CMC makes repetitive tasks simple. For instance, when deploying our 3-node cluster for the first time there was a firmware update each system needed. A simple click to update button took each node through the process on its own, with no further interaction or disruption required.
For larger clusters, ease of management like this is important. If we were to grow the cluster from three nodes to four, the LeftHand OS scale-out model stripes all data for all volumes across all of the nodes.
The new resources including storage, memory, CPU and the like, are aggregated and applied for all volumes to provide linear scalability in performance as new nodes come online. Either way, the cluster remains online the entire time. In addition, using what HP calls Peer Motion technology, customers can protect their StoreVirtual investment over time. This also works with the StoreVirtual VSA, which offers quite a bit of flexibility within the environment.
HP StoreVirtual arrays include a robust core set of enterprise data services. Primary among these is thin provisioning which is supported and recommended for all applications. HP has demonstrated consistent performance between thin provisioned volumes and full provisioned volumes and sees equal performance between the two. The result is efficient and lean thin provisioned volumes over time. LeftHand OS snapshots are thin provisioned to be space efficient and do not require capacity reservations, which helps the be more space efficient.
The LeftHand OS has a bunch of other core features as well that help it differentiate. Multi-Site SAN lets organizations automatically and synchronously mirror data between two or three sites for increased availability. HP offers One View for vCenter which allows most storage tasks to be completed through familiar hypervisor tools; similar tools exist for Microsoft Virtual Machine Manager. All of these software features are included in the core pricing of StoreVirtual without a need for further licenses.
When creating a volume manually, simply choose the volume name and size. The Network section is where users can configure elements such as the speed and duplex, which is found in the RCP Status tab. To maintain our independence, none of our reviews are paid for or managed by the manufacturer of equipment we are testing.
The following list shows the amount of flash and HDD, how much is usable in our specific configuration and what networking interconnects were leveraged. We have also included list pricing for comparative purposes. The StorageReview VMmark protocol utilizes an array of sub-tests based on common virtualization workloads and administrative tasks with results measured using a tile-based unit.
Tiles measure the ability of the system to perform a variety of virtual workloads such as cloning and deploying of VMs, automatic VM load balancing across a datacenter, VM live migration vMotion and dynamic datastore relocation storage vMotion. The StoreVirtual stayed with the pack up until 6 tiles, where it started to slip compared to the Dell and XIO solutions.
In terms of peak performance the StoreVirtual topped out at 8 tiles, where others climbed to tiles. An issue we saw during the VMmark testing process was the length of time required before hitting a passing run at the highest tile capability. The X-IO ISE was also able to hit 10 tiles on the first run we performed, by its use of an incredibly aggressive tiering process that moves data quickly in real-time.
Adding another node would of course resolve this issue as the performance scales linearly, especially for this test which is the most intensive an array faces in our lab. The TPC-C benchmark comes closer than synthetic performance benchmarks to gauging the performance strengths and bottlenecks of storage infrastructure in database environments.
Our SQL Server protocol uses a GB 3, scale SQL Server database and measures the transactional performance and latency under a load of 30, virtual users and then again with a half-size database of 15, virtual users. For Windows-based environments, the MPIO driver is easy to deploy and offers tremendous performance gains.
With the driver installed the cluster peaked at over k IOPS and 1. With a load of 15k virtual users, the StoreVirtual was the second-best performer with The average latencies had a good spread across the group with 15k virtual users; there was a modest gap between the top performer XIO with 19ms and the StoreVirtual , which had an average latency of 26m. There the gap nearly doubles to the PSXS. During the six-hour preconditioning period we verified the data we were measuring was fully tiered on the SSDs to show optimal performance out of the array when configured as eight LUNs.
The fastest write performance went to the XIO with 8. The XIO was the top performer in both read and write functions in terms of max latency, with The StoreVirtual had the second-best read performance The StoreVirtual had the most consistent read performance of all of the devices tested 0.
The XIO was the fastest device for most of the test offering the lowest average latency, while the StoreVirtual overtook it towards the end of the benchmark. The results of the maximum latency benchmark were fairly consistent with the other mixed protocols, although in this test the StoreVirtual started out stronger than it did in past benchmarks. With the exception of one latency spike, the XIO was the highest performer.
The standard deviation benchmark showed results very similar to the first two mixed protocols; the StoreVirtual started out weak and finished relatively strong, the XIO was the top performer for the most part, and the Dell EqualLogic PSXS stayed at the bottom of the pack through the duration of the test.
On the software side, StoreVirtual comes with integrated lights out iLO 4 for system management, and Centralized Management Console CMC for cluster management and a deep pool of data services. The HP licensing scheme is simple, all of these features are included in the unit price.
In synthetic 4k random transfer workloads, the StoreVirtual was the strongest in read performance, ranking at the top in throughput and latency. There are a number of ways companies approach hybrid storage.
Effectively what this means is in our case, the 2. In total the is a refined system that is a complete offering playing well on its own as primary storage for a small business, or as part of a larger storage scheme in a classic ROBO hub and spoke configuration.
