Comparison of Best Software Defined Storage (SDN) Solutions & Vendors
To help you find the best software defined storage solutions, IT Central Station ranked them based on hundreds of real user reviews, from our esteemed community of enterprise technology professionals. You'll find comparisons of pricing, performance, features, stability and many other criteria. Read below to find out what your peers have to say about software defined storage vendors such as VMware, Nutanix, HPE, IBM and others.
The total ranking of a product, represented by the bar length, is based on a weighted aggregate score.
The score is calculated as follows: The product with the highest count in each area gets the highest available score.
(20 points for Reviews; 16 points for Views, Comparisons, and Followers.)
Every other product gets assigned points based on its total in proportion to the #1 product in
that area. For example, if a product has 80% of the number of reviews compared to the product
with the most reviews then the product's score for reviews would be 20% (weighting factor) *
80% = 16. For Average Rating, the maximum score is 32 points awarded linearly based on our
rating scale of 1-10. If a product has fewer than ten reviews, the point contribution
for Average Rating is reduced (one-third reduction in points for products with 5-9 reviews;
two-thirds reduction for products with fewer than five reviews). Reviews that are more than 24 months old,
as well as those written by resellers, are completely excluded from the ranking algorithm.

What do you think of EMC ViPR?
During the recent EMCworld event in Las Vegas among other things, EMC announced ViPR (read announcement here). Note that this ViPR is not the same EMC Viper project from a few years ago that was focused on data footprint reduction (DFR) including dedupe. ViPR has been in the works for a couple of years taking a step back rethinking how storage is can be used going forward.
ViPR is not a technology creation developed in a vacuum instead includes customer feedback, wants and needs. Its core themes are extensible, open and scalable.
On the other hand, ViPR addresses plenty of buzzword bingo themes including:
Agility, flexibility, multi-tenancy, orchestration
Virtual appliance and control plane
Data services and storage management
IT as a Service (ITaaS) and...
One of the main features of Spectrum Virtualize is it virtualizes the servers from the storage. We have a very large infrastructure. A major advantage is when you get the aged storage arrays and you have to replace all of those. Last summer, we replaced four petabytes of aged storage arrays. They were old and past end-of-life. But we did that seamlessly, without... more»
There are things that occur when you get to this size and capacity. We're very large, i.e., petabytes. When you get to that sheer volume of the numbers of things, it is too big for people to keep track of. So, it's okay if you have 50 volumes, and I can watch them. I can assign people to watch them. But when you have 5,000, it's not possible anymore. So you need... more»
The HPE StoreVirtual Network RAID-10 (mirroring between nodes) is the most valuable feature. This allows for multi-node redundancy. If one node fails, the other in the cluster picks up the entire load. I have had nodes fail due to upgrade and... more»
I administer a 100% virtual environment. To use the HPE StoreVirtual VSA edition, I did not have to buy an expensive external array. I was able to create two 3.27TB usable HPE VSAs from all the older disks I had laying around. Granted,... more»
The management console upgrade needs a bit of work. In some cases, it will not upgrade due to the non-removal of other HPE StoreVirtual Components. Be sure to remove other components first. The other issue is a login issue. There is a... more»
The most valuable feature is probably data migration so we can bring in back-end systems and swap data out. Our end-users, and even our other system administrators, don't have any idea that we've moved storage around. It's got full features,... more»
* Reducing our costs: We used to have all tier DS8 storage. Even though we had Spectrum Virtualize in front of almost all of that, we still had almost all DS8. * We've been able to bring in multiple tiers, flash systems, and V7000s * We can... more»
A feature that is already there, if I remember correctly, is encryption. I think it is coming out, or it is already there. That is a key management piece. Right now, we're doing an encryption on the back-end flash systems on the V7000s. It's... more»
Performance, redundancy, scalability and cost-effectiveness. StorPool delivers superbly in all of these areas - something no other product we have either tested or deployed has been able to do consistently.
Since deploying StorPool, we have experienced no unplanned outages or performance issues. Our technical and engineering teams no longer live in a permanent state of high alert due to storage outages or throughput degradation due to ‘hot... more»
Live and historical performance statistics would be useful, though my understanding is that this is on the way in a future release. This could likely be combined with general health monitoring via some sort of dashboard.
That my team can manage it. The server guys can actually manage the storage on their own. It was easy for them to learn to use the console and provision the storage quickly. It was a long, painful process to get storage from the storage team... more»
It's easy to set up, easy for my team to manage, the tools are pretty easy to learn, and it's important for us to be able to provision storage quickly in my environment, so as soon as we get a new node in, we can get it up and running very... more»
The only thing that comes to mind was we had some issues with once we used up storage and then moved it out and had empty, white space areas, but getting that storage back is a long, painful process. You actually have to run a manual command... more»
The ability to provide block storage and object storage from the same storage cluster is very valuable for us. We are using Ceph as back-end storage for our OpenStack cloud. Ceph provides: * Block storage for storing the OpenStack images or... more»
Ceph does not deal very well with, or takes a long time to recover from, certain kinds of network failures and individual storage node failures. I believe the community that supports Ceph is working on this. They will be providing solutions... more»
StoreVirtual has been real good for us. We started with the original P4300 LeftHand SANs before they became StoreVirtual. What I love about those is the two nodes and the mirroring back and forth, and you can't lose anything. It's very solid, and we haven't really had any trouble with those either. We have a newer StoreVirtual that we've connected to one of the... more»
We were primarily looking for a storage system for a management cluster that was separate from our fiber channel SAN. Fiber channel SAN is all of our mission critical stuff, but we needed somewhere for our management systems that are watching... more»
We leveraged StoreVirtual to provide a software SAN for our management cluster of vSphere - this allowed us to run monitoring and management applications on a separate infrastructure from the rest of our Fibre Channel based vSphere clusters... more»
The user interface needs to be updated. It's getting kind of long in the tooth, and the user interface makes it look a lot more complex than it actually is to manage, and I think that you can mask a lot of that with a refresh of the user... more»
LizardFS allows storing data across several nodes (which run on commodity hardware, even inside virtual machines) and also has a built-in HA mechanism. This works very well if failover can be done in a manual or simple way (e.g. by using... more»
We have been running LizardFS for a while now, but only inside a testing environment. It will be deployed to production soon and it will help to make specific files available inside several datacenters in a very fast and efficient way.... more»
Well, if you don't have a support contract and therefore don't have acess to the automated failover mechanism, you need to build it yourself. This can be achieved by using common open source software, but you will need to know what you are... more»
The SVC gives excellent performance with tiered storage behind it, and the Spectrum Control suite. The newest versions that I have now are very useful in terms of managing, monitoring, and alerting. The full suite handles everything I need. We have had a lot of success through the years with Virtualize, which was originally just SVC, and we use it heavily. My... more»
It has the ability to seamlessly move hardware in and out as we refresh technology. It provides transparency, because of its advanced copy features. Our disaster recovery has also improved drastically because I am able to use a lot of the Spectrum Virtualize features to create multiple copies that we use to test and do development. Our disaster recovery plan... more»
Incredible IOPS increase in storage: IOPS is required to fulfill a disk job faster. It is input/output per second. When you request a report on your SQL server, you need as much as IOPS you can. So many IT guys put their most important... more»
Basically, our company needs IOPS to solve the bottleneck on the storage side, but storage upgrade costs were awful. Instead, we chose FVP and achieved IOPS values nearly 6-10 times faster without any hardware upgrade.
Right now, you can only use this technology in VMware environments. Definitely supporting different OS and hypervisor systems would help this product reach a much larger community. This issue has not actually affected me. However, other... more»
Using SBC, a valuable feature is the mirroring, which is the virtualization of the disk between disparate places. One of the things that we use it for, is that we can bring any storage underneath it. Not only will it recognize it and put it... more»
I think probably one of the biggest benefits of this solution is that it is relatively easy to use and easy to understand. It's intuitive. The front interface is very intuitive. I can have any of my administrators know what to do with it with... more»
For improvement considerations, I would probably say multiple sites. Right now, I'm doing two, and I believe we can go to a larger scale than that. But I think that having to go into three or four sites, where I would have more of a grid-type... more»
ADT acquires companies (and things), so we end up with odd hardware. We bring it behind the SVC and it allows us to migrate stuff off of it seamlessly. SVC can also cover up a host of defects of the underlying storage. Dell Compellent, which... more»
There are several good features, many of which have similarities to that of competitive offerings from other vendors (replication, snapshot). Compression is quite useful, but for me the most useful has been the virtualisation of back-end SAN... more»
My view of how the product has aided my customers varies. The replication functions have assisted in the relocation of whole data centres from one site to another, the snapshotting is of value in providing several versioned recovery points... more»
It has been integrated into our production systems, thereby not having as much online storage. We're using the archiving functionality. When I say reliability, I mean that we are operating 24/7. The product enables us to retrieve our client... more»
They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments. Supposedly, it was going to be corrected in 8.1, restoring it back to the original UID, but it wasn't done.
It is a single pane of glass management interface, so once the storage is allocated to SVC, they only have one place to go to manage it for everything. Then, my Power customers using Power VC can allocate storage themselves from Power VC, because it has integrated with SVC, so AIX admins do not have to know anything about storage. It is very powerful.
Easy and cheap High Availability is most valuable for us. Also, the VSA (virtual appliance) version enables us to reuse already installed hardware. You do not need to worry about RAID and components anymore, because even a whole chassis loss... more»
We are able to build server clusters without external storage and still provide high availability. We are able to run the VSA version inside the actual servers, thus converging server and storage in same units.
Benefits for us are pretty much the simplicity, ease of implementation, and the ease of maintenance. Flexibility and responsiveness to customer needs are key. They are the things that allow for ease of disaster recovery with global mirror,... more»
I already discussed possible improvements with some of the guys from Hearnsley. One of our frustrations is when you go to expand volumes in a global mirror environment, you have to stop everything in order to expand. So that's one of the... more»
Primary Use Case
It provides a control plane for the data plane. With Spectrum Virtualize, you can extract the physical storage, then hide it and give it flexibility. Most of my implementations have been on-premise. We could stand up a software instance someplace else and connect to it. However, most people that I work with get it in an appliance format. They use it to migrate off of existing storage. When lease expiration of something is occurring, they will use it to save value and migrate everything. Then, I will see them in a traditional Fibre Channel, a SAN connected to server architecture, or both in virtualized servers as well as standalone. I do not personally manage any instances, but I have several dozen customers that I have deployed this solution for, so it is up and...
