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.

Gives us a lot of advantages when we need to expand resources

Stability can be improved. Adding all these new features is nice, but we are now at the level where most of the features you need in production are there. The stability is not from a day-to-day operations perspective, but more from a supportability perspective, because currently some of the support scenarios require you to completely evacuate hosts or the complete cluster. That sometimes can be a stretch. This would clearly be an improvement if the support teams were given additional tools to make that easier. Upgradability could be a bit easier sometimes. We are now where vSAN can be updated without ESXi, but there is still enough dependency. So that would be good if that actually would be uncoupled even more. Dashboards are there, and we use vROps as well. So, we have all the beauty of capacity planning and everything over there. That's not really something where we need a lot of other things.

Quotes from Members

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

Pros

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

"I appreciate the performance."

"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."

"The high availability of the product is the most valuable feature."

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

"The initial setup was extremely simple and straightforward."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

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

More Pure FlashArray X NVMe pros

"The most valuable feature of Dell Unity XT is data duplication. Additionally, the management interface is simple, and is not a hassle using it. You don't need too much to learn or to be familiarized with it."

"Their support cases are all handed through the portal. The support contacts me when they need to do upgrades. It has been great. It's all very well-handled, scheduled, and performed."

"I like the idea that it can compress and dedupe inline. That is quite a stunning feature for mid-range customers."

"It is nice the way ESRS works with remote support, being able to remote in and take a look at problems proactively."

"Unity's are more easily administrated, so we need fewer people to do the administration. We have less overhead because of that."

"In the hybrid version, I would say they are fast. They have fully automated storage tiering. In the all-flash version, higher performance, compression, data replication."

"The technical support is very professional and provides quick responses."

"The scalability is really good now that they have the Dynamic Pools. We don't always have the money to buy complete write sets when we have to expand the storage, so now with the Dynamic Pools we can add disks on the go."

More Dell Unity XT pros

"Storage policies are used to perform operations in the VMs. This feature allows you to create storage policies for VMs to get performance, high availability, I/O policies, etc."

"The product is highly scalable and significantly supports our organization's needs."

"The most valuable feature is the ability to continue our business needs and have higher visibility. It has definitely increased our business productivity levels."

"It is easy to find information out there, not only from searching the web, but even the times I have engaged VMware support."

"Being able to deploy multiple applications with virtual servers is the most valuable for us. The capacity of the system is quite constant so it's got some of the good features."

"vSAN is one of the easiest implementations of any VMware product. It's almost like click it to enable it, then you're almost done."

"We didn't only choose vSAN; we chose VMware because of SR-IOV, which is more on the hypervisor level and not on the vSAN storage. It's part of the whole system."

"The most important thing is the simplicity of the product. It is a well-established product with good stability."

More VMware vSAN pros

Cons

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

"We need better data deduplication."

"There is room for improvement in the pricing of the product."

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

"I would like to see replication and DR features in the next release of this solution."

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

"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."

"It feels more suitable for small and medium-sized businesses rather than enterprises."

More Pure FlashArray X NVMe cons

"One of the issues we've had is that controllers have crashed several times... We've had a lot of problems with the storage processor, SPBs. We've actually had them crash."

"Stability is the problem. We've had stability issues with it. We've had problems with the iSCSI interface. We've had it for two years now and for two years we've had problems where a service processor will drop, we'll lose connectivity to LUNs, we'll lose connectivity to the storage, issues like that. No matter how we've tried to chase it down, everybody just points fingers at each other. The only thing that changed in our environment was that the Unity solution was installed."

"This solution would be improved with the addition of flexible raid volumes."

"They can certainly improve in terms of monitoring."

"More integration with VMware would always be helpful, plugins that go directly into the vSphere management. A single pane of glass is always beneficial."

"There are a lot of things that can be done with it. It's got Cloud IQ, but I think it's not as mature as it could be, they could make it more effective. They could make it more comparable to some of the other products out there that have cloud analytics. The amount of insight that the Unity product is able to give, at this point, is okay, but not class-leading. Some of the other data-reduction technologies, like deduplication, are not to the level of other competitors and what their products provide."

"This solution could be improved by offering containerization. This is something many of my customers are looking for."

"It's very frustrating that it's not backward-compatible with the previous platforms, so it's a struggle for a lot of our customers."

More Dell Unity XT cons

"VMware vSAN could improve by adding NAS and object storage."

"The only thing I can think of at this time is to improve the performance monitoring and performance visibility within the GUI."

"I would like to see a little bit more documentation on the initial setup, and a little bit more explanation on the expandability: How to extend out your vSAN much more simply through the console because, a lot of the time, you have to do it through the command line."

"The vSan product uses a software system called Vsphere to monitor the system. It is sometimes difficult to manage the PCs within the systems."

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

"They can package it in a way that is specific to the hardware infrastructure and the hardware platform. It should stay fairly up to date with the drivers and the manufacturer issues. The problem with uncoupling the proprietary technology and component capabilities is that by uncoupling them, you run into some concerns or challenges over the poor performance model. These concerns really come when you start talking about high performance, high bandwidth, and high availability types of environments. While vSAN is a leader, in a critical view, it is not about being cost-effective. It is more about the immediate impact of money loss to the business in critical applications where we want to maintain a continuous operational 59 model. It is, however, good for QA/QC tasks. I don't necessarily know how it works in regards to VDI or virtual desktop infrastructure."

"They should make the software updates easier. We should be able to upgrade it more easily."

"vSAN has a significantly higher license cost post-merger."

More VMware vSAN cons

Pricing and Cost Advice

"The licensing is on a yearly basis."

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

"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."

"As far as the licensing costs, everything is included in the license."

"We pay approximately $50,000 USD per year in licensing fees."

"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."

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

"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."

More Pure FlashArray X NVMe pricing and cost advice

"The price is up a little bit from what we used to pay so I'm hoping that it's a little bit of a better system than the VNXe was. But I still think it's a good value. It's new, so I'm sure there's room for the pricing to drop."

"The solution is very expensive."

"The support you're getting with it is probably an underestimated value that comes with the box you're buying."

"Pricing for this product is manageable, though slightly higher than comparable products."

"All the licenses are included from day one of your purchase of the product, so you don't have to buy licenses separately. There are no additional costs to be paid for the maintenance of the solution."

"It is priced at around or under $50,000."

"Looking at it based on cost per gigabyte, it's certainly very effective."

"The solution is very expensive."

More Dell Unity XT pricing and cost advice

"The price of VMware vSAN is expensive and there is an annual license required."

"The price is expensive."

"The product is quite expensive, regarding the open source solution."

"This solution requires the purchase of a license."

"The cost of VMware vSAN is reasonable."

"There is a license required for this solution, it is a one-time payment. However, if they want support for the solution, it can be paid annually or for three years."

"The first 1-2 years of purchasing vSAN will be expensive. Thereafter, the longer you are running it, the more cost savings you will have."

"If you compare the price of VMware vSAN with other players like Nutanix and Cisco, its price is good, but could still have some improvement."

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.

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."
