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.

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.

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.

EMC's Unity is not comparable to the performance of an IBM FlashSystem option, but it is fairly close in performance profile to the just released Storewize V5100 model 424. If you provide the initial amount of storage you are going to purchase and your expected capacity growth rate, plus any workoad/performance info you have on hand, and we will give you a very quick TCO and performance compar...

For a performance comparison, I use a vendor-neutral benchmark portal like Storage Performance Council: For SPC-1: a) IBM storage, including All-Flash (performance) https://spcresults.org/benchmarks/results/top10/performance/spc1/1?field_peer_review_status_target_id=48&field_sponsor_target_id=18 b) Overall top 10 SPC-1 (performance) https://spcresults.org/benchmarks/results/top10/performance/spc1/1?field_peer_review_status_target_id=48&field_sponsor_target_id=18 c) Overall top 10 SPC-1 (price/performance) https://spcresults.org/benchmarks/results/top10/price/spc1/3 For SPC-2: a) Overall top 10 SPC-2 (performance) https://spcresults.org/benchmarks/results/top10/performance/spc2/1 b) Overall top 10 SPC-2 (price/performance) https://spcresults.org/benchmarks/results/top10/price/spc2/1 I also look at specific benchmarks from the vendors: a) IBM https://www.ibm.com/developerworks/community/blogs/InsideSystemStorage/entry/spc_benchmarks_for_disk_system?lang=en b) Dell EMC https://www.dellemc.com/resources/en-us/asset/white-papers/products/storage/h15161-dell_emc_unity-performance_metrics.pdf

I am about to take delivery of a Unity 400 with SAS and have never considered an IBM hardware so i am not able to compare based on experience.
