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.
Raanan Sitton - PeerSpot reviewer
Offers cost-effective storage for small companies with budget constraints
IBM FlashSystem 5300 is offered at a very low cost in Israel, which is advantageous for small companies. However, other features like deduplication and compression do not perform effectively. The price sensitivity makes it a viable option for clients with budgetary constraints, as it allows us to secure deals based on the cost rather than advanced performance.
Anna Sofo - PeerSpot reviewer
Since switching, our clients have reported improved performance and reduced latency
I like NetApp AFF's deduplication. The solution's AutoSupport feature is efficient and effective because customers are notified of potential issues before they experience problems with NetApp. The support is sold based on metro clusters, so they guarantee the client's business continuity. NetApp has an Active IQ app that allows you to get information on your smartphone.

Quotes from Members

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

Pros

"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."
"The most valuable feature of this solution is its ease of use."
"Everything, especially the VMs inside, is pretty fast."
"It has good, reliable, fast storage."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"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 FlashSystem 900 consistently delivers performance below 1ms for read/write. This performance is essential for an effective SVC stretch-cluster configuration across two datacenters, and presenting active-active storage to the customer."
"IBM FlashSystem 5300 is offered at a very low cost in Israel, which is advantageous for small companies."
"IBM's technical support do excellent work."
"The initial customer technical support was efficient and effective."
"The Flash core models offer amazing performance."
"The most valuable feature of the solution is compression."
"This solution is convenient, user-friendly, convenient and reliable."
"The most crucial feature of IBM FlashSystem is compression."
"High availability"
"I work on the infrastructure engineering side. I usually get to install NetApp appliances, and I like how easy the installation is. It seems to be easier than other technologies that we use."
"The NVMe flash cache is the most useful feature. It lowers transactional speed even more."
"One of the main features that differentiate AFF from the FAS products, or some other technologies used, is the footprint of these arrays are significantly smaller than the traditional ones. Also, the performance that you get to these new arrays is really significant. You can see a huge difference there. By switching to it, we can achieve more storage performance and efficiency as well as in the long run lower down some of the TCOs due to reducing the footprint."
"The in-line dedupe, and the compaction saves us a lot of space because most of our AFFs house VMware VMDK files."
"We have SQL clusters across the United States. It has sped up our IOPS and made it a lot easier for users."
"From my standpoint, NetApp AFF is the most powerful enterprise solution. I find it to be highly flexible, allowing me to do whatever I want."
"The cloning and snapshot features are the most valuable. With snapshot backup, we can clone a big database in minutes. We take a lot of snapshots for clients in different environments."
 

Cons

"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."
"Adding some functions to the product would be beneficial."
"There is room for improvement in the pricing of the product."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"The UI for this solution needs to be improved."
"In the future, I would like to see integration with enterprise backup systems."
"They could add more support for file storage and different types of storage."
"The installation is not easy. You need to have extensive knowledge to handle it."
"We use some open-source tools for monitoring, such as Grafana and it should be bundled along with IBM FlashSystem."
"Our customers have raised concerns about the limitations of the FlashSystem 5200 and 7300, which only offer a 32-gigabyte connection."
"The security features can be improved such that the encryption does not affect performance in any way."
"Additional licenses might be added for the fundamental licenses, such as those for copying and flash copies."
"The ease of installation should be improved. We had issues with the configuration model."
"This solution could be improved by offering greater amounts of storage."
"The solution's pricing is a bit high so there is room for improvement."
"We only had a few upgrade issues."
"Their backup software could be improved."
"This is an expensive solution that could be cheaper."
"I would like NetApp to be more aware of organizations that don't run it on a public cloud. Everything is built on the cloud, so if you want to run BlueXP in an environment like ours, it's a real pain because it wants to host too much info on the cloud."
"There are no RDMA capabilities in CIFS (SMB) and NFS protocols."
"Going forward, I would like more performance analytics on it, on the area itself, instead of using some other tool."
"We would like to have more behavioral reporting."
"We don't have any challenges with NetApp. We only need to update it on emerging software and versions that are put out or any enhancements that they've included or things that they've deprecated. NetApp's product is superior, so our engineers must stay on top of all the features and things that they've taken away."
 

Pricing and Cost Advice

"The support cost per array is about $20,000 a year for 24/7 support."
"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."
"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."
"Given its price, Pure is not the first option."
"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 licensing is on a yearly basis."
"The product is expensive."
"Our licensing fees are $500,000+ USD."
"The cost of the IBM FlashSystem is lower than the HPE solution."
"Our customers would like IMB FlashSystem to be less expensive."
"We have no issues with the price as it is very competitive."
"I'd rate the basic licensing and the Virtualize software a ten out of ten, and the extra Spectrum and other an eight out of ten."
"The tool is cost-efficient."
"Regarding licensing make sure you add at least three years software maintenance from IBM at the beginning, because you will not be able to download firmware updates or any fixes/patches without this."
"They've been much more aggressive in the last five, six years than they were before that."
"It pays to go back and get the best price you can from your supplier. The first offer is not always at the best discount."
"Look at the different options that NetApp offers. Look for a model and option which fits your needs correctly. Don't buy a low-end product for a high-end job."
"I looked at other vendors for other potential projects and thought NetApp's pricing was very competitive."
"We have used the solution’s thin provisioning to add new applications without having to purchase additional storage. We use thin provisioning on all of our flash arrays at this point. It gives us the choice to be able to overprovision and take advantage of compression, compaction, and thin provisioning all at the same time. We can get more out of the purchases that we make."
"The price of NetApp is very expensive, but we don't know how much Pure is, so we can't compare."
"I think the pricing and licensing are a little high, but compared to those of other storage vendors, it's within reason. After the three-year prepay, the extended warranty is a little expensive."
"With other options, you need to buy a couple of different products to achieve the same outcome."
"In addition to simplifying the management across a mix of solutions, AFF simplifies the cost. That was one of the main reasons we purchased AFF."
"ATTO bridges add to the total cost of the system."

NetApp vs. XtremIO
Is there another storage platform as feature rich as NetApp FAS? I think it is fair to say that NetApp FAS running Clustered Data ONTAP is a very feature rich platform – the move to the clustered version of ONTAP has brought many next-generation features including Scale-out and Non-disruptive…
