Works well, is easy to implement, and has upgrade analysis capabilities
We love the product. Pure Storage works really well. The CAT tool and also the ability to upgrade the unit's place grades are great. It allows for in-place control or upgrades. It's a very simple implementation. They have a good tool to analyze upgrades. The stability is good. Technical support has been excellent.
Srikanth Purushothaman - PeerSpot reviewer
Easy to set up with good data compression technology and useful deduplication
The initial setup is very straightforward. Even upgrading the firmware is very nice. You don't need to shut down. Previously, we used to have a shutdown, and now we hand over to one more processor, upgrade the one processor, and then switch back to this process, and then we'll do the upgrade for the process so there is no downtime. I'd rate the ease of implementation nine out of ten. Since we are holding almost all the data, which are all critical and confidential, the deployment is always on-prem only. It takes a maximum of two to three hours. The solution is almost finalized before ordering. We plan what has to be done, and how many services have to be connected through the HBA. Based on that, the number of fiber ports should have been ordered along with the system. Normally, it comes with two fiber-channel HBA adapters. We used to order with four channels instead of going for a sand switch. We connect three servers directly into process A and process B. Before getting into the server, all the servers should be up and running with the HBA connector with the fiber cable ready. Once we install the server, we will see if the firmware is up-to-date or if it is one month old since the shipment takes at least one or two months before it reaches our hands. If there is any new update, we will check with them to see whether the new firmware is good or if there are any bugs in it. If the support team says there is no bug, it means we will update the firmware and create a pool. If it is a hybrid pool, we'll do a mix and combinations of flash as well as the NSS for the images. For the data, we have only the flash itself, and we use a rate six for the data. Previously, with the regular SaaS drives, we used to have a rate ten; however, with the flash drives, we used to have rate five or rate six only. Normally, in-house inside the rack, we need two people. Otherwise, one engineer itself will do. If it is a flash drive, only one person itself will be enough. If it is three bay drives with 144 TB or 288 TB, then we'll go for one more person to fix inside the rack. Once it is fixed, the installation will be done only by one person. For maintenance, normally, we check the firmware updates within a month, or we check every 30 to 45 days to seek out firmware updates. We provide maintenance to our customers. For other issues, we might call technical support. Most things we can manage.

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.

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…

I saw that you have doubts about what you chose. I have a lot of experience with the constructor, honestly I can recommend Dell EMC Unity XT All-flash which can guarantee you a ratio of 3:1 signed by Dell and you have to deploy all types of workload from block to file. You can also rely on the native cash and fast cache functionality for increasing application performance

First of all the decision should be taken looking at similar products in terms of capacity and performance. I will show a few aspects helping the decision, comparing Unity Xt480f and AFF220 (both chosen by distributor to be in the price range for capacity): 1. Comparing 2 systems with the same capacity and performance: pricing is the first to look at: 1a. Cost per GB, war capacity and usable capacity (+Unity) 1b. Cost of adding capacity (+Unity) 1c. Cost of licensing per GB / per added capacity (+Unity all included) 1d. Cost of maintenance after initial contract (+Unity same for all life ) 2. Comparison of CPU/MEM, we choose Unity XT because of better CPU cores/frequency and memory per controller 3. Percentage of space lost in various configurations. Our goal was to use Dynamic disk pools, available on Unity. Easier upgrades/downgrades. 4. If virtual volumes are considered, Unity has a VASA provider included in the controller, Netapp is using external VM. 5. Product lifecycle 6. Inline compression / deduplication, performance, From the above 1=80%, 2=5%, 3=10%, 4+5=5% We went to Unity XT480 where on the same budget we got 20% more usable flash capacity, while enough slots remain for future upgrades.
