Featured Reviews

Eugene Hemphill - PeerSpot reviewer
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.
Syed Habib - PeerSpot reviewer
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.
Pramod-Talekar - PeerSpot reviewer
Enables efficient multi-environment cluster deployment and resource management with versatile features
While VMware vSAN is quite comprehensive, if we are running multiple infrastructures, applications, databases, and other elements, having a diagnostic tool to identify the actual problem area, whether application-side or infrastructure-side, would be beneficial. A proper monitoring tool that encompasses both applications and infrastructure would help in quickly resolving issues.

Quotes from Members

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

Pros

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"One of the best features is the support, which is excellent."
"It has benefited my organization because it has reduced time to insights."
"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."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"Snapshots provide a unique feature for testing and make management more comfortable and easy."
"Dell Unity XT is quite scalable and can be scaled up to the petabyte level."
"It has made deployment, configuration, and maintenance a lot simpler."
"The Dell EMC unity interface is simple to manage. We manage it by ourselves. We create logs to store data."
"The All-Flash models are pretty fast for the vast majority of our remote workloads."
"Veeam Backup integration: Veeam is the defacto standard for backing up of virtual environments."
"It's easy to use, easy to manage, easy to troubleshoot, and the process support is good."
"Scheduled components are sourced from Korea based on their quality selection, with the actual purchase taking place in Vietnam. The notable features include cache memories and MOS feeder in Dell Unity. Additionally, the storage dynamics are managed uniformly on a global scale, whether it is a simple or wide-ranging configuration."
"The most valuable features of vSAN are its simplicity to deploy and that we can use commodity disks in our servers without complexity or need for external storage arrays or storage specialists on our teams."
"The features of vSAN allow us to reduce our operational complexity to a large degree."
"The most valuable features are Erasure Coding, Deduplication and Compression, and the advancement in stretching regarding replication."
"Since the storage space is local to the hosts, it reduces the overall response time and improves the performance."
"Easy to deploy and manage."
"The most valuable features are productivity and data storage."
"Scalability in vSAN has been really good. It's very easy to add nodes in, to automatically generate the drives and the disk groups. It has been a piece of cake, surprisingly so."
"The technical support is good. We are always thankful for the technical support from VMware. They are very supportive when we have a technical problem."
 

Cons

"In terms of what needs improvement, the dashboard and management could be simplified."
"I would like to see replication and DR features in the next release of this solution."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"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 pricing is higher than competitors."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"Dell Unity XT could improve the compatibility of some of the features. Some of my customers had some problems. Additionally, it would be beneficial for the solution to have advanced AI and ML features."
"We would like an AI feature that would protect the backup and minimize the consumed space so we can maintain the quality of the backup. This would help us minimize our IT cost in terms of the backup procedures."
"Maybe deduplication would be something that would be better to have. Also, it's a fairly new management interface, so work is still being done on that. But compared to other vendors and previous EMC storage, the Unity is really good."
"I would like it to be a little bit easier to contact support. We can contact support, but we have to go through a phone tree. We get routed to different places. I might call support to say that I need a drive replaced and get transferred to three different groups before I get to the group I actually need."
"The interface can be a little challenging for someone new."
"I would like to see better compression, better dedupe. It's not nearly as good as what is built into the XtremIO. I understand why that is the case, but if they can take some of that technology and leverage that a little bit better in the Unity array, that would be great."
"For the integration of the VPLEX function for Cross IDC structure, they should integrate the function into the SP controller."
"It could go faster. Make it bigger, better, and faster at a lower price, and I am there."
"It could have some automation. We haven't involved ourselves in a lot of automation around the vSAN environment capabilities. We're still running it using a very traditional setup. So, there could be some plugins to automate it using third-party environments, such as Jenkins."
"I am looking for more of a software-defined storage platform that uses different protocols, such as iSCSI, NFS, and CIS, and maybe also has an object as part of that. They should 100% make it more of a storage-based product where it is not linked just to VMware, and it also has NFS and iSCSI built-in at a scalable level. They should turn it more into a dedicated storage-as-a-service platform instead of just being built into the VMware kernel. Their level one and level two support is not at all good, and it should be improved."
"This solution is not great for large file shares/object/rich media repository."
"Disaster recovery needs to be improved, when there is a crisis, there is a problem with what is the quickest way to get out of it."
"We would really like them to look at what Nutanix did for day-one/day-two operations deployment: Bringing in the equipment, getting it deployed, getting it setup, and ease of use of one-click for deploying our 30-node solution. With vSAN we had to go into each one individually and set it up."
"Pricing is something of a concern."
"It would be ideal if clients didn't need to monitor the solution on a daily basis."
"Lacks an integrated backup solution."
 

Pricing and Cost Advice

"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."
"The support cost per array is about $20,000 a year for 24/7 support."
"The product is expensive."
"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."
"Our licensing fees are $500,000+ USD."
"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."
"What they really like is the easy licensing now - Dell EMC has caught up to a lot of their competitors - based on not having to charge for everything, and they can get everything in one bundle."
"The price is good for commercial grade storage arrays."
"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.""
"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."
"There is an annual charge for the license of this product. It has better pricing than its competitor: Pure Storage."
"Pricing is as high as it has ever been for EMC."
"It is priced at around or under $50,000."
"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."
"If they could reduce the cost, it would be better. Licensing costs are something that they could take care of. If you are a smaller and strong IT team, then VMware vSAN is a very good product. If you want to expand in the service provider space, then you will have to go for an open-source solution like OpenStack. We are now looking at OpenStack because we sell licensing costs. We are a service provider, so the IT component data is a substantial component in our overall costing. We feel that OpenStack might help us to cut down the licensing cost. Therefore, we are looking at SAS storage instead of vSAN. SAS is open source, but it is not wise to have open source without having the backend support. We are using RedHat SAS, and it is an open-source solution. You can also have a free version, but we are using it with support from RedHat so that we have somebody to back us up in case we have a problem. If you do normal business, then IT expense is 1% or 2% of the total turnover. The higher licensing costs sometimes don't make difference to the big companies who are not service providers and are using it only for their internal use. For them, the IT cost is 1% or 2%, but for an IT service provider, the IT costs will go up to 15% to 16% of the total cost of the operations. This is where the licensing costs become irrelevant. For example, the licensing cost of using VMware, VC, and vSAN is 8% of my monthly revenue. Every month, I pay about $35,000, and, with the revised plan, it will be something like $50,000 or revenue of 600k per month, which means almost 8% of the revenue is going into VMware licensing. In a very competitive world, 8% as a cost element is huge. So, if I can bring it down to 2%, I save 6% in revenue expenditure. In terms of profit, 6% of 30% is something like another 25% increase in my profit. My profit can be almost 25%. It would be 20% to 25% in case I am able to handle the licensing costs and bring them to a very low level. Because these IT costs are substantial for us, that is why we are going with OpenStack. OpenStack has a limitation that it requires more hardware. There will be some increase in the hardware cost, but overall we will save 5% to 6% of our licensing cost by using OpenStack."
"It is an expensive solution. There should be more flexible with licensing to allow small businesses the essentials of the solution's features."
"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."
"The solution requires a license. The payment is on a yearly basis and It is not overly expensive."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a seven out of ten."
"The vSAN is somewhat expensive to license."
"The vSAN licensing is not an inexpensive product. It does cost more than hypervisor."
"I feel the pricing to be reasonable."
