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.
Kirubel Behailu - PeerSpot reviewer
Enhancing storage management efficiency with user-friendly experience
Our customers are using Zadara for their research and development environments. We provide infrastructure for government projects, but we are often not fully aware of their specific usage.  I typically use it for our infrastructure and offer both Zadara and Microsoft Azure to our customers Zadara…

Quotes from Members

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

Pros

"On a scale of one to ten, I rate Pure FlashArray as ten."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"Everything, especially the VMs inside, is pretty fast."
"Technical support has been helpful and responsive."
"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"It has good, reliable, fast storage."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"With all-flash it should be able to scale. You probably just need one 4U device and you have terabytes of space."
"The most valuable features of Dell Unity XT are the data compression for all of our VMs up to four times and the performance is good."
"It is scalable, and we usually recommend Dell Unity XT to small and medium companies."
"Integration; We use the product with VMware, and also use it with Syft for home directory and departmental shares."
"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."
"Because I always need to trouble shooting for IOPS & database (DB) performance issues. I can quickly focus on what is part of the issue. I can decrease downtime and can plan next year's extended capacity budget."
"On a scale from one to 10, I'd probably give EMC customer support an 11. It's been really good. We do have premium support, which means if we have a problem, it gets solved really quickly."
"The most valuable feature is that the solution is a hybrid system, so you can do both block and file storage."
"Zadara is a fully-fledged platform, and our customers are happy with its use."
"Zadara Storage Cloud having 24/7 management saves me support and engineering costs because the storage and computing are managed by a third-party. We are able to focus more attention on the customer, which is truly our core business. Even at 1:00 AM or 2:00 AM at night, someone will answer, which is important."
"One of the most useful features is that they provide iSCSI as a service."
"It provides very satisfactory storage performance."
"Being able to scale on demand, and being able to get out of our security operation center, and not having to purchase hardware upfront, has drastically reduced the overhead that was required to maintain our information. We have also gained additional capabilities in terms of speed of replicating that information."
"The most valuable feature is the flexibility in terms of deployment options."
"The processing is much faster with this product."
"The most valuable feature of Zadara is its ease of use and safety. Overall the solution is a complete package, it has all the features needed."
 

Cons

"In terms of what needs improvement, the dashboard and management could be simplified."
"Maybe the price can be reduced since the solution is very expensive."
"I would like to see replication and DR features in the next release of this solution."
"In the future, I would like to see integration with enterprise backup systems."
"I'd like to see the product implement active replication for vehicles such as VMware."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"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."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"Our request to Dell EMC for improvement was in the reporting and monitoring areas. Dell EMC built up a cloud ID so that we could see the overall storage numbers. We needed to have the proper KPIs to be able to see and manage things."
"What I'd like to see is a little more detail on the networking side. I can go into where it's showing me the replication, but when I go into the network it just gives me broad-based information. I don't know which replication job is actually feeding it. I have to go in and rely on other apps."
"Recently, they released products, sometimes without proper testing, it seems."
"It might be nice to have more integrated features instead of having everything as a separate module, like the networking. The networking is attached separately in the back. It would be nice if that was more integrated with less ports."
"We have had some downtime. Nothing is perfect. Unity’s have had some code-release problems, versions that, from a compatibility perspective, had some glitches which caused an outage. But, given the amount of Unity’s we run, that has been fairly minor and it hasn't happened at scale or across all of our Unity’s."
"We've also encountered an issue when it comes to migrating to compressed LANs on the Unity, and during the Storage vMotion. It appears that the compression algorithm is overwhelmed, and when it becomes overwhelmed it just stops compressing and writes the raw data to the destination. We later copied internally another Storage vMotion to another compressed LAN and achieved much higher compressions on that internal copy. It would be really nice if there was a way to automatically throttle, as a part of a Storage vMotion, to say, "I want to gain the maximum benefits from the compression algorithm, so throttle back the Storage vMotion to implement 100 percent compression.""
"As the solution continues to grow and gain more traction, things will come up that will just continue to deepen the integration between VMware, vCenter, and all those other components. Anything in the divisibility there and additional tools is always great."
"For the integration of the VPLEX function for Cross IDC structure, they should integrate the function into the SP controller."
"Currently, when we do firmware upgrades, it sometimes causes issues and is not as nondisruptive as desired."
"There is room for improvement in pricing as it is currently quite expensive."
"The initial installation was difficult because many steps required the command line interface (CLI). Maintenance can also be complicated, especially when deeper troubleshooting requires navigating the CLI and searching for logs."
"The range of support of VMware could be better. It can support Windows, however, it cannot support other operating systems like IBM AIX. This needs to improve."
"Having iSCSI over the internet using a VPN, the IPSec tunnel is really the only thing that I find missing from this product."
"There are still some storage features that they lack. For example, other vendors implemented the auto-tiering feature a long time ago, while Zadara Storage Cloud is just coming out with this feature today. So, they are a little bit late compared to the market."
"Some of the features are a little bit slow to come to market."
"The cost is not favorable as Zadara does not provide competitive rates for regions like South Africa and Ethiopia."
 

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."
"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 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."
"We pay approximately $50,000 USD per year in licensing fees."
"The support cost per array is about $20,000 a year for 24/7 support."
"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."
"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."
"It is priced at around or under $50,000."
"Currently, we buy directly from Dell EMC. We've tried going through resellers before, but we've found that if we go directly through Dell EMC, we get a good a price from being with the government."
"I rate Dell Unity XT’s pricing a nine out of ten."
"The Dell EMC Data Protection license covers everything, like a one stop shop. All our options are covered."
"The flexibility is important. We still have a lot of customers that have a use case for non-flash, yet you can also build the flash version as well."
"It is shipped with all licensed, included for this product range, no need to buy additional licenses"
"One of the most valuable features is its cost. It was inexpensive compared to other arrays that we were looking at."
"The pricing and licensing are very simple and the cost is predictable, although, like everything that you pay for as you use, you have to be mindful of what you're using."
"It is a nice licensing model and it makes it quite simple because we just pay for what we use, and the bill that comes shows us exactly what customers are using what resources."
"One of the factors that ruled out several providers was cost. They were way too expensive for the volume of data that we needed and the speed at which we needed to be able to manage it. There aren't a lot of providers that can do that."
"For our use, it's appropriately priced and overall, it's proved to be very cost-effective against other tier-one vendors."
"The price of Zadara is very good and it covers everything. There is no subscription needed."
"If you just take the street price of Zadara Storage Cloud and look up the price or cost per hour, then you could think that Zadara Storage Cloud is extremely expensive or a solution only for enterprise use. That is not true. You need to compare the entire system. This means that you don't stop looking at just the street price, but you need to consider all the features, requirements, and costs of support as well as the extra cost that other vendors have. Other players just play with hidden, additional costs. Everything is included in Zadara Storage Cloud's licensing cost; what you get is what you pay for."
"The pricing is very competitive and the fact that they have very compelling discounts for multi-year commitments is great."
