Performance boost (MegaCash, Parallel I/O technology) and Continuous data protection (CDP) are the features we love most because security and being productive are big points for us. DataCore is helping us focus on our core business and keep it running, which is important for our customer success. Supporting of Automated-Storage-Tiering (AST) is a good feature that saves money.

DataCore's ability to seamlessly move virtual volume data between storage pools as well as their synchronous mirroring has made maintenance and disaster recovery planning achievable. DataCore's auto-tiering feature also allows us to use our SSD arrays efficiently. View full review »

The most valuable feature is auto-tiering, which allows for storage pools containing different speed storage systems and the data automatically moved to the most appropriate pool. View full review »

SANsymphony is a very versatile product and its vendor's agnostic nature allows us to pick and choose our hardware platform. Its redundancy allows us to perform maintenance 'on the fly' and protects our data from all manners of failure. View full review »

We have gained in scalability. The most valuable feature for us is that we can adjust the size of the storage very easily, without stopping production. The product is easy to administrate. View full review »

The features I have found most valuable are the active-active, or so-called grid technology, and the integration into our VMware vCenter. Our vCenter is now much easier to manage. View full review »

Redundancy and improved performance in terms of storage with auto-tiering are the most valuable features. It needs just two nodes for the operating system and licensing. View full review »

Mirrored vDisk, and creating a third node with asynchronous replication to get the data out of the datacenter. The new third node is great for an always-on experience. View full review »

No more vendor lock-in, overpriced drives, or forklift upgrades. With DataCore SANsymphony, you can utilize just about any storage you wish with this product such as another SAN, NAS, JBOD, FusionIO, etc. If Windows can see it as a non-removable drive, you can use it with SANsymphony. Also, you can use this to mirror any of these various types of storage, which is awesome for migration. Say, for example, you have an HP SAN and you want to migrate off it to your own JBOD-type storage, or you have two sites with two different storage SANs that you want to replicate data between. With DataCore, it is possible to mix and match just about any storage platform you want to use. As software-defined storage, the system is designed to run on top of Windows Server OS (which can be virtual or physical) and can utilize the server's RAM to provide disk cache. This makes our 7.2K HDDs class storage run really fast, allowing us to use a bottom-tier class of drive and get the performance of a much higher class of drive. Also, if we have to add capacity or replace drives then we can just order replacement drives off the web, saving us quite a bit of money. Of course, we still use "enterprise-class" drives but we don't pay through the nose to buy hardware. If we want to upgrade the Ethernet ports from 1Gb to 10Gb then we just do it. The same goes for FC. If we want to upgrade from 4Gb FC to 16Gb, we don't have to do a forklift upgrade. We just buy the HBAs and we're off the to races. The other great thing is DataCore keeps their product on VMware's approved HCL. So even if you have a SAN (backend storage) that falls off the HCL with VMware, because it's virtualized storage behind DataCore, you're covered. If you put the storage behind DataCore then you won't have to worry about VMware's HCL any longer. Because of this fundamental practice, DataCore was one of the first storage vendors to support VVOLs. The ability to pool the storage to leverage thin-provisioning is a huge saving in space and costs. View full review »

The most valuable feature of this solution is the ability to migrate from one storage area to another one easily. The evolution of the solution by adding new storage without having to go through a difficult migration is very helpful. View full review »

Auto-tiering moves data to fast disk if needed. Works great. I don't have to think about the second set of data. View full review »

DataCore is very fast storage, applications start faster, and database access is improved. You can attach different storage pool and DataCore chooses where to store data (the most accessed data are on the faster storage automatically). Replication helps us to replicate virtual servers on different sites easily. View full review »

Parallel I/O, because there is no performance degrade nor cache hit when there is a 100% update and 70/30 read/write. There is no performance impact and latency is just 20 ms. View full review »
