Helps to save money and resources with the data compression feature

One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

Efficient data replication and fast IOPS have improved operational performance

Dell and a partner jointly implemented this solution in Auvink. We installed the Flash, which makes our IO operations fast and efficient. Replication is available, allowing us to replicate data simultaneously from one site to another. All-flash technology and vTXT enhance speed, and the IOPS are faster. The cache's IOPS are much better. Snapshots provide a unique feature for testing and make management more comfortable and easy. The platform is multi-supported and certification is more convenient and easy to manage.

Expensive solution that requires professional services for installation and implementation

I'm still using a different solution. I only took two servers with vSAN to support one application that needs one feature that only VMware has. If not for that feature, I wouldn't touch VMware. Now, I'm looking at products like Nutanix, Silver Peak, Flexione, and FortiGate. For products that I choose, I don't need a specialist of that vendor. In VMware, I need a specialist in VMware. That's the issue I have with VMware. It's not like I can take any IT person, and they will know what to do. I need to make sure he will do the call, get the certificate and time to practice.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Overall stability is very good. It is a very stable solution."

"The initial setup was extremely simple and straightforward."

"The solution uses newer technology for deduplication and compression."

"The solution is scalable."

"The solution is very straightforward to set up."

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

More Pure FlashArray X NVMe pros

"We've never had an issue with storage."

"We can put all the virtualized servers in one place, so our customers can share and manage the devices very easily."

"It has reduced complexity."

"A lot of the Unisphere interfaces are greatly improved in terms of monitoring capabilities, alerting, and ease of use. Setting up the storage and the file system are all just a few clicks away."

"Its most valuable feature is the storage alarm."

"I don't think I've ever seen latencies above 10 milliseconds unless it was something that wasn't the array that was messing up. The thing is rock-solid."

"We use it to implement all our VDI solutions."

"It's an all-flash Unity, With that compression feature, it's comparable to a hybrid. That is one thing that we definitely like."

More Dell Unity XT pros

"The product's initial setup phase was very straightforward."

"One of the valuable features of vSAN is it has a universal type of technology that allows you to deploy it on any server or hardware. Competitors, such as Nutanix, provides the AOS and can be deployed only on certified hardware. For vSAN, it does not require any kind of certified hardware."

"The most valuable features are Erasure Coding, Deduplication and Compression, and the advancement in stretching regarding replication."

"IOPS is comparatively best to run VDI solution."

"The installation is very easy."

"To me, VMware is a leader of the visualizations. I think everyone just follow VMware."

"VMware vSAN has greatly reduced refresh spending."

"The feature we have found most valuable is the compatibility of VMware products with VCF and VMware Cloud Foundation."

More VMware vSAN pros

Cons

"The software layer has to improve."

"One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them."

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

"We've seen that when we create a POD in synchronous mode, it increases the latency."

"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."

"The tool's portfolio is minimal. It is expensive."

"It is on the expensive side."

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

More Pure FlashArray X NVMe cons

"My only complaint would be some of the CLI Help files could be a little more detailed, but that's very minor complaint. We were trying to run some commands just to see how the storage snaps were interacting with the storage array, and it was a little difficult to look up exactly what commands should be run. The Help files detailing what exactly the commands did wasn't as detailed as we would have wanted them to be."

"It would be better if there were more integrations."

"We have only used this solution for less than one year so I don't have any improvements suggestions yet."

"Issues with slow responses from the support team."

"The one thing that we would look at would be if they were to expand the file level features, just to give us a balance or a tier between it and Isilon options out there, for unstructured data."

"Scalability is not good. We have a Unity 300, now we have to do a data-in-place conversion for the next upgrade because only 150 slots are supported, not drives, only slots."

"I would like the UI to look better."

"We noticed in the last release of code that there were some inefficiencies around getting our data efficiency up in terms of dedupe and compression."

More Dell Unity XT cons

"Troubleshooting tools could be improved."

"Better options would be clustered nodes, or even cloud configuration. There is room for improvement in cloud configuration, we typically do web browsing for management."

"The UI falls short compared to other solutions. It needs some development to make it more user-friendly."

"We have encountered some challenges related to administrative tasks and licensing issues for the product."

"It should be easier to use."

"Its price could be improved. It is too expensive for our clients."

"When we talk about improvements for vSAN, there is some way to go from a at least stability perspective. Adding all these new features is nice, but we are now at the level that most of the features you need in production are there."

"I would have liked it to have been more scalable. It's scalable but not as much as, for example, the ScaleIO systems were or the Kaminario"

More VMware vSAN cons

Pricing and Cost Advice

"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."

"With VMware, we pay $300,000 annually."

"The support cost per array is about $20,000 a year for 24/7 support."

"Given its price, Pure is not the first option."

"The licensing is on a yearly basis."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."

"Our licensing fees are $500,000+ USD."

More Pure FlashArray X NVMe pricing and cost advice

"Because of the attractive price, we were able to get rid of more expensive arrays, standardize, and get rid of a lot of spinning disks. We also got rid of more expensive flash that we weren't properly utilizing."

"In the SQL Server instances in our data warehouse, we immediately saw a great return on investment."

"The pricing of Dell Unity XT is good."

"Licensing is fine. We worked with a sales rep to purchase our Unity."

"It is an average priced solution."

"Here is our major complaint with pricing. Dell EMC comes to us and gives us a price. We are like, "Well, this doesn't even compare to what we got on the last project." We say, "No, you should bring it down to this level." Then, they come back again and we are sort of in the middle again. I am like, You already sold us other stuff at a better price. We are not going to just say, 'Yes,' because we are out of time.""

"The license is not required, but we must renew the support every year, every two years."

"The solution is very expensive."

More Dell Unity XT pricing and cost advice

"It is an expensive solution. There should be more flexible with licensing to allow small businesses the essentials of the solution's features."

"There is a license to use this solution and we pay approximately $30,000 annually. There were not any additional fees required other than the license. The solution is expensive."

"The product’s pricing is a bit higher than other solutions."

"It is fairly cost-effective for entry to mid-level performance based on the underlying hardware components."

"ROI from an administrative perspective is clearly much better because I only have to deal with one user interface."

"The solution requires a license. The payment is on a yearly basis and It is not overly expensive."

"Its price could be improved."

"This solution is expensive. Nutanix provides us with Acropolis Operating System (AOS) along with its hardware, while VMware provides vSAN, vCenter, and vSphere which all have separate licenses and costs."

Reviews from Real Users

Below are some reviews and helpful feedback written by Dell EMC Unity XT users.

A Systems Engineering Manager at a manufacturing company says, "It is definitely one of the most robust, solid, well-performing products that I have dealt with. It is set it and forget it, which is pretty amazing." He also mentions, “We can do both block and file storage on one unit without purchasing a separate device.”

Peter S., Senior Technical Specialist at a healthcare company, states, “The most valuable feature is reliability. At the end of the day, it just runs. This solution is easy to work with and easy to maintain.”

PeerSpot user Melvin T., Senior Systems Engineer at Prosperity Bank, explains that the solution is “easy to use and we can add LUNs or space without interruption to end-users. We're able to access it from just about anywhere, as long as we have access to a browser. That feature is really neat because sometimes we will go to a different data center or a different site, and if we need to access it to see a LUN or to see any type of storage, we can do that. That's one of the big takeaways with Unity."

VMware vSAN is a software-defined storage product that is used in collaboration with VMware ESXi hypervisor and that provisions and manages storage based on policies, regardless of the underlying hardware. The solution enables you to prime your business for growth through its seamless evolution (it is integrated with vSphere and requires no new tools), its flexibility, and its multi-cloud capabilities. As an industry-leading software, VMware vSAN provides high levels of performance with minimal impact on CPU and memory.

VMware vSAN Features

VMware vSAN has many valuable key features. Some of the most useful ones include:

Storage policy-based management (SPBM): VMware vSAN supports storage policy-based management for automated management of storage profiles.

Software-defined data-at-rest encryption: With this VMware vSAN feature, you can prevent unauthorized access of data at rest.

Multiple nodes: VMware vSAN provides clusters that can include as few as 2 nodes or as many as 64 nodes.

High security and availability: VMware vSAN offers stretched clusters, allowing more than one virtualization host server to be used in the same setup, promoting higher security as well as availability.

Deduplication: VMware vSAN’s deduplication compresses data to ensure efficient storage management and security.

HCI mesh updates: VMware vSAN clusters can share storage capacity with non-HCI Sphere clusters and can adopt HCI without having to scale computing resources and storage or replace existing servers.

Simplified file services: With VMware vSAN’s file services, backup of file shares is simplified. You can use APIs that allow backup and recovery software vendors to integrate with your VMware vSAN file services, which enables backup software to track new data and add scalability enhancements to files.

Reduced risk: VMWare vSAN reduces the risk associated with digital transformations by utilizing existing tools, skill sets, and solutions.

Reviews from Real Users

Below are some reviews and helpful feedback written by PeerSpot users currently using the VMware vSAN solution.

PeerSpot user Yves S., CEO, Cloud Evangelist at Comdivision Consulting GmbH, says, “vSAN gives us a lot of advantages when we need to expand resources. We have an overall larger host infrastructure, and we split that up for specific customer test and use cases. In that specific scenario, we can easily add more hosts or reduce the number of hosts in the environment.”

A reviewer who works in Infrastructure Security explains, “The ease of use is great. The initial setup and upgrade process was pretty straightforward. And, technical support is great.”

Laurent N., Director at Softlogic, comments, "The feature that I have found most valuable is that it is easy to deploy. It is easy to create and delete virtual servers. It is easy to create the load balancing and the clustering."
