Over 253,522 professionals have used IT Central Station research.
Compare the best Software Defined Storage (SDS) vendors based on product reviews, ratings, and comparisons.
All reviews and ratings are from real users, validated by our triple authentication process.
The total ranking of a product, represented by the bar length, is based on a weighted aggregate
score. For Views, Comparisons, Reviews, and Followers the score is calculated as follows: The
product with the highest count in each area gets the highest available score of 17.5 points.
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 17.5% (weighting factor) *
80% = 14. For Average Rating, the maximum score is 30 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.
Some years ago when we started working with Nutanix the solution was essentially a stable, user friendly hyper converged solution offering a less future rich version of what is now called the distributed storage fabric. This is what competing... more»
As a system integrators Nutanix offers a solution which is highly standardized that can be deployed in very timely fashion compared to legacy three tier-, converged generation one- and even most competing hyper converged solutions. This... more»

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...
I think performance and cost are the most valuable features of VMware Virtual SAN. We're stringing up an entire virtualization environment for VDI and RDSH through Horizon View. When we compared the cost of a traditional SAN versus VSAN,... more»
I'm from the cloud virtualization side of things, so consolidating the data allowed us to set up the VSAN instead of a traditional SAN, and allowed us to do faster deployments without having to interact with as many teams. It's simplified our... more»
I know it's coming, but I'm really excited for the encryption. I know it's on the all-flash, which is fine, because we're migrating to that anyways. Nonetheless, the encryption would be great for at-rest data, because I don't want to rely on... more»

What do you think of Atlantis USX?
Which features have you found most valuable? Let's start here... We've found that Atlantis USX helps remove some major inefficiencies around storage silos by unifying all storage types into a highly-optimized pool of storage resources. These resources are then made available to virtual workloads, desktops, and applications. From there, you can control these resources (again, across a number of different types of storage repositories) from a policy-based perspective. This allows you to optimize capacity, performance, and overall storage management. There are a couple of big features that we like with Atlantis USX. First of all - there are a lot of different types of ways to deploy this: Hybrid (SAN/NAS or Local Storage), Hybrid using DAS, All-Flash, In-Memory, Simple Hybrid (requires...
The most important feature for us is the converged infrastructure, which is all this tool is about. There is no need to manage separate storage areas in SAN/NAS environments. Storage management comes built-in with the vSAN tool. Storage is... more»
The management client, i.e., the Flash-based client, is just not up to the mark. I’m really waiting for the HTML5 client to be fully ready and all the features are implemented to it. This, of course, is not a vSAN issue but a vSphere issue.... more»
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 level of statistical performance data it is able to report in real time is extremely useful. I can see what my VM’s hosts and guests are doing form a single pane of glass and identify issues before they would otherwise become apparent.
Site-to-site replication needs some work. It’s not as feature rich for a disaster recovery implementation as I would like to see, but my understanding is that it is slated for improvement in near-future releases. DRS-like functionality is... more»
I give the replication feature a 10 out of 10. The GUI for snapshot replication gives you a lot of flexibility to schedule asynchronous replication, bandwidth control, and disk-rebuild resource allotment. High Availability is a 10 out of 10,... more»
When we bid on projects and scope out the work, we usually will have three design iterations that we follow -- a Multi-Site, Single-Site P4500, or Single-Site P4300 class setup -- depending on what is needed. All three build-outs use the same... more»
For disk utilization I give it a 7 out of 10. In the typical network RAID 10 coupled with horizontal shelf RAID 5, you lose over 55% of your disk. But this is a price I am willing to pay to have highly-available storage. I would look into... 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 features are Prism and Acropolis, as they simplified our jobs and give us the opportunity to lower operational costs without reducing the current day-to-day operation performance. We are using VMware 3-TIER architecture... more»
As opposed to before, the Nutanix platform allows us to pay as we grow instead starting with a large scale. Management seems to like this idea, as it will save us from overspending the budget. We can improve IT utilization and reduce costs by... more»
We're thinking about hosting SAP HANA on the Nutanix platform, but we are still unsure about the path as SAP still has not certified Nutanix to host SAP HANA yet. Nutanix should make SAP a close partner and certify their product with SAP so... 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.
If you really want to squeeze all of the value out of this solution, it should deployed in an all-flash configuration. The all-flash vSAN solution allows customers to take advantage of newer features such as erasure coding, deduplication and... more»
vSAN is a very cost-effective solution for just about any data center. It is very easy to deploy, scale and manage. The entire solution is built on commodity hardware, so customers do not have to break the bank (or budget) to invest in this... more»
Snapshot management is something that continues to improve with each release of vSAN. Earlier versions experienced performance degradation, but each version gets more and more efficient with snapshots. The new snapshot format known as... more»
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 storage policies allow the administrator to define which VMs have specific storage requirements. For example: Our critical VMs have an increased flash read cache percentage enabled. This improves the overall performance of these machines.... more»
The ease of managing and configuring vSAN. This means that all our VMware administrators are now able to do the daily maintenance and operations. Previously, only a couple of IT administrators were responsible for maintaining our previous... more»
* The daily maintenance can be high, especially due to the lack of documentation and reporting in vCenter, and only on the vSAN health page. * If the vSAN cluster can’t self-heal due to an internal error, we can’t repair the vSAN cluster... more»
The most important functionality is the ability to extend cluster storage and cluster computing power securely without loss of data. Also, the ability to set up an extended cluster on multiple sites in a much simpler and easier way than with... more»
It is precisely the possibility of being able to extend the capacities of the cluster of storage and calculation by the simple addition of one or more physical server which makes us lean on this solution in a secure way. Moreover, with the... more»
This product is usable in many cases. It can be used for a wide range of applications. It is also possible, for example, to parameterize a stretch cluster at the very least without going to a costly solution based on conventional storage,... more»
Currently, we are on version 6.2. Having all flash, I would say that the most valuable feature for us is deduplication, as it gives us better utilization of the space available. In the latest release, there are already features that we have... more»
We face the same challenges most organisations do; probably the most common one being that of keeping up with growth and expansion, while keeping within the budgets. vSAN is very scalable, so we can plan our costs well in advance, knowing... more»
I think that the product is evolving in the right direction, most of the improvements and suggestions we had in mind are already available in 6.5. Obviously, there is always room for improvement. For example, in our case, we had to go with... 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»
We are running a training lab environment with ever changing setup and, therefore, iSCSI is the most flexible solution to provide storage to any point inside our datacenter. HP StoreVirtual is a scale-out, clustered iSCSI storage solution... more»
In the past, we were exclusively Fibre-Channel focused with all the associated disadvantages of running a separate FC SAN with particular array types. Every host we wanted to connect to shared storage had to have an HBA installed. With iSCI... more»
From my perspective, these things are missing: * Homogeneous management of 3PAR, StoreVirtual and MSA * Remote Copy * Integration of Priority Optimization with VMware vSphere and vVols on the VM level straight from the vSphere web client *... 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»
