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

"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

"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 most valuable feature of this solution is reliability."

"The most valuable features of this solution are its ease of use and performance."

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

"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

"It has benefited my organization because it has reduced time to insights."

More Pure FlashArray X NVMe pros

"It will certainly help us scale bigger. If I look at the footprint, the VNX's was multi-rack. Now, all of a sudden, we're only at a portion of a rack. And, obviously, if we can scale within the same rack - we can certainly see that by the number of hard drives we've had to put in - we can scale a lot more easily."

"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."

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

"With all-flash it should be able to scale. You probably just need one 4U device and you have terabytes of space."

"We just recently started using the Dynamic Pools, so while it's scalable, we actually find it valuable that we can just pop in one or two drives when we need to, instead of having to add a whole RAID set. That has actually been very handy for us."

"It's easy to manage. We access it and manage it through Unisphere and have had no issues. We're able to provision storage, create consistency groups, create RDMs for our virtual machines. Creating it through Unisphere, it automatically adds the data store on the VMware side and rescans the LUNS. We just have to add and configure the storage in one place and it takes care of everything, which is very handy."

"Stable data storage platform which promotes ease of management through its multi-cloud support. Remote support provided to users to address issues is very good."

"Being all-flash makes everything super-fast. It's also great to manage. That's the easiest part. We also have another SAN, from Pure, and the Unity is easier to manage than the Pure."

More Dell Unity XT pros

"The ability to have a disaster recovery option for our end-users by being able to use VDI and the vSANs, and the ability to do replication across multiple data centers, are valuable to us."

"It has a single pane of glass for management and operational control, which is the most valuable feature. The integrated storage is also valuable."

"VMware vSAN's most valuable features are the capability to consolidate standalone physical infrastructure into virtualization and the ease of management."

"It is easy to work with, easy to handle, and easy to manage."

"We are finding that vSAN is a lot more scalable and adaptable, because we can go in with hybrid arrays for our lower-end storage needs or with all-flash versions of vSAN for places where we need more performance, and it's coming in at a lower cost point than an actual traditional array."

"The setup is straightforward."

"Allows us to implement more quickly, and to ease the maintenance."

"it's easy to scale, it's easy to predict IOP needs, and you can design for low latency using all-flash... Also, for setting up new clusters for VDI quickly, it's nice. You don't have to wait on an order for a storage vendor to ship you a system and help you configure it, you do it all yourself. And the sizing guides are pretty straightforward."

More VMware vSAN pros

Cons

"The software layer has to improve."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."

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

"It is on the expensive side."

"There are some challenges with data encryption and reduction."

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

More Pure FlashArray X NVMe cons

"Licensing costs could be reduced."

"The solution can use improvement with the patch cluster like the Synchron and Active replication."

"It should be lighter. It takes up a ton of rack space. It would be nice to have a smaller footprint."

"We did encounter a firmware bug which actually caused loss of data. There was some heartburn around that. But in general, it has operated as expected, except for that bug."

"In the dashboard there could be notification of duplicate files and the like, so we don't have to rely on Windows to do that."

"It needs more functionality and the ability to move across more landscapes."

"Recently, they released products, sometimes without proper testing, it seems."

"It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions."

More Dell Unity XT cons

"I would like to see replication as part of it. I would also like to see direct file access, being able to run SIF shares and NFS and the like. I think that would be critical to continuing the use of it going forward."

"There are certain shortcomings in the stability of the product where improvements are required."

"I would like for the next release to be a bit cheaper."

"VMware vSAN needs to improve its features because other solutions have more advanced features."

"I would like more integration with the hardware when it comes to disc types and supporting the newer types of storage."

"The architecture of vSAN is not good. vSAN works with objects, such as disks, and it causes problems with availability."

"The ability to access SAN environments with fiber channels (or even NVMe) would be a good addition."

"I would like compression and deduplication to be offered for offloading hardware, instead of doing it with software. That would be nice."

More VMware vSAN cons

Pricing and Cost Advice

"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."

"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."

"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."

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

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

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

"The product is expensive."

"The licensing is on a yearly basis."

More Pure FlashArray X NVMe pricing and cost advice

"When you look at what Dell EMC is compared to, like NetApp, they're all priced pretty similarly. I think the pricing of the hybrid model is good."

"The ROI is right where we need it to be. It's a reasonably priced array."

"The pricing was quite okay compared to others. We probably got it cheaper because we were the first ones out of the gate, but I would say that it's good value for the money."

"We checked both HP and Dell and we determined that Dell EMC was a better option."

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

"The price of Dell Unity XT could improve. However, it is a one-time purchase."

"There is no capacity license for XT and no additional costs for expansions. I would rate its pricing as four out of five."

"The price of Dell EMC Unity XT is not reasonable. They should lower it because the trend is to move to the cloud. They have to protect their market by giving commercial or financial incentives."

More Dell Unity XT pricing and cost advice

"We pay for a license to use the solution through our company CapEx and then we continue to pay annually."

"The only problem I have with VMware is the price. It is a good product, but it is expensive."

"It is too expensive."

"Perhaps a bundle, like Essentials, would allow more businesses to make the leap to the product."

"Its price could be improved."

"I would rate the licensing model a three out of ten, where one is expensive, and ten is cheap."

"The vSAN licensing is not an inexpensive product. It does cost more than hypervisor."

"It is not a subscription model. It is a purchase model, but it is very important that you also buy technical support from VMware. This is probably the only disadvantage of vSAN. It depends on the use case, but it can be very expensive."

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."

Dell Technologies

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.
