Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."The ease of management is one of the most valuable features of this solution. I would have also said that it's pretty fast but now our SQL servers are starting to beat it up pretty bad."
"At this point, I don't know anything that they could provide in a better way."
"Very efficient storage"
"The most valuable features of Pure Storage FlashArray are the management view of the solutions, ease of provision, and deprovision, it is fantastic."
"The tool is simple and easy to use. It has neat features like protection from device removal. Moreover, you can undo the deletes. The solution is easy to work with and not as complicated as CAC"
"There was a dramatic improvement in operating costs just as a result of the environmentals and space, let alone the cost of the unit itself."
"The most valuable feature of Pure Storage FlashArray is the complete set of functions it provides."
"It is always out of the box, and ready to use."
"The ratio between the physical storage and the storage we use is very high."
"Inline compression"
"The most valuable aspect is the use of solid-state storage drives instead of spinning drives."
"It provides a full feature set without separate licensing (deduplication, compression, snapshot, asynchronous replication, stable performance, etc.)."
"Ease of use: My installers - my administrators over the system - they love how easy and fast it is to install and spin up a LUN and get going."
"The increased performance is many times above our previous array performance in all metrics. Integration with vSphere features is also a definite plus."
"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."
"Scale out is a differentiator for them, especially in the enterprise market. It's key for a lot of customers."
"The most valuable features are Erasure Coding, Deduplication and Compression, and the advancement in stretching regarding replication."
"All the features are working great."
"As a function of our core business, it's a sought after tool that helps us provide analytical support across a wide spectrum of client needs. It's allowed us to test out in our connected restaurant - "TheWorks" - a fully-functional restaurant experience center that allows our clients to discover the value of our connected solutions firsthand. We deploy vSAN in this customer-like environment within a hyperconvergent infrastruction (HCI) to give our clients a better understanding and help optimize data and the end-users' experience."
"If we decide to expand, vSAN could offer us some flexibility. We are researching ways to set this up from a new data center, which is located somewhere different from the current location right now."
"The flexibility is most valuable. Being able to manage things quickly if something goes wrong is also valuable. Very recently, we had one node that went down due to a power problem, but there was really no major impact on the systems running on top of it."
"The scalability has been quite good."
"Stability-wise, I rate the solution a ten out of ten."
"The most valuable thing about vSAN is that all of its features have been working well for us for the past two years. We haven't had an issue with them."
"The primary drawback is the cost, which can be prohibitive for small configurations."
"In some cases, we get into very in-depth conversations around movement of specific data and, what's more, chunk sizes. The documentation lacked any description or information on that."
"I like what they're doing, but some of my customers complain that they do not have all the bells and whistles and knobs to fine-tune workloads that some of the competitors have. In my opinion, that's good. All customers don't have dedicated storage gurus, and they can get themselves into trouble if they fine-tune too many of those high-performance knobs, but they do get knocked down. Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE. I personally think 95% of my customers are better off letting the system fine-tune itself. That was something that you needed to do 12 or 15 years ago, but now with all-flash, the technology can handle what it needs to handle. Customers just end up shooting themselves in the foot if they are tweaking too many default settings."
"I would like to migrate to the cloud in the future and know how that would actually work with this product."
"The price should be lower."
"It is not possible to create a cluster on top of multiple arrays."
"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."
"Pricing could be better in comparison to other solutions."
"I would like to see LDAP for the management panel; I've been notified they might be currently working on it."
"I would love to see capacity on its DRAM. I know it's not cost effective for them to do it, but I think that it could be a big differentiator and was a big differentiator from the beginning."
"A single pane of glass to monitor/manage multiple arrays would be helpful."
"The front panel of the drive shelf doesn't always seat firmly."
"I would like to see them work with Cisco, so it comes off the FIs, instead of having to go through my 10-gig network."
"I would like them to improve the look of the product’s external casing and shelves."
"I think it should have better performance with small files. With big data, its performance is top notch, but it is difficult to load small files."
"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."
"The pricing could be better when it comes to renewing the licenses."
"VMware vSAN could improve by adding NAS and object storage."
"The technical support, it's not satisfactory. Whenever we raise a ticket it takes a lot of time to have an engineer get involved sometimes, or we receive a less experienced engineer. We then have to repeat the situation to the next engineer which all takes time."
"I would like to see more comprehensive lifecycle management. The current path and process for upgrading or updating the firmware, as well as the storage controller software to interact with that firmware, is fairly manual and not very well documented. A little more time and effort spent on the documentation of the lifecycle management for vSan would be really great."
"vSAN does not have online dedup. When opening the inline dedupe, the performance will be lower than off inline."
"Based on my testing, I would like to expand deduplication to include hybrid deployments and not just for all-flash deployments."
"This solution is not great for large file shares/object/rich media repository."
"Because of virtual storage, the system reaches reserve storage for its functions. It also consumes a certain amount of storage, which then results in the creation of a fault tolerance for the system. All of this adds to a lot of capacity being consumed in terms of storage for each drive for vSan. I find this to be one drawback of using vSan."
