Cristian Ion - PeerSpot reviewer
Senior Information Technology Engineer at Eta2u
All-flash storage has unified my clients’ workloads and has reduced TCO through efficient data services
The pricing and licensing of Everpure FlashArray is a problem because Everpure is considered more expensive than competitors. IBM, Lenovo, and Dell are more aggressive on prices. It is a very complicated market, especially now, and I understand the prices are higher at Everpure because of the software and all the enhancements it has. However, in this competitive market, we have a big problem selling to customers that are on a tight budget. A product with better pricing would be a win in the end. The RC or C20, for example, was a very good product that I could sell more easily than other options. Everpure FlashArray//C is sufficient for most workloads and virtualization workloads if you do not have very large databases. A product like that helps, and perhaps a new product in the future that is a little cheaper than the current options would be a possibility to gain more market share. I see the return on investment clearly from using Everpure FlashArray, but the challenge is selling it to customers for the first time. There are many customers who fall in the sweet spot where they are too small for an X or even a C model. They need something a little cheaper, they have the money for a cheaper version, and they need the performance of a Pure system. These customers could be more easily approached if Everpure offers a version of a local device in the future that is even cheaper than the C-class. I am trying now to help customers understand the concept behind AG1. I know that AG1 is not profitable if capacity is less than 50 terabytes. However, some customers would be very willing to pay for 25 terabytes in a cloud operated by Pure and to have it accessible with very good speed. We will see what the future brings.

Offers high performance and dependable support for fast storage needs
The most valuable feature of IBM FlashSystem is its robust back code. When integrated properly into the environment and configured according to the guidelines, it provides a very solid infrastructure that does the job on demand. Additionally, IBM FlashSystem offers competitive pricing and reliable performance. The hardware is dependable, ensuring that it functions effectively when the setup is done correctly.
Mir Gulzar Ahmed - PeerSpot reviewer
IT Manager at Synergy Computers
Unified storage has delivered efficient AI analytics and low latency for critical workloads
There might be some lag or response time with respect to support cases, but even then I will rate it 8.5 out of 10. All of this is the same for all product ranges, whether E-series, NetApp AFF, or FAS series, because they are very efficient to respond. The only reason I rated it 8.5 is because the warehouse for spare parts, when a problem comes, a spare is needed to replace it, for example, a disk. In Pakistan, they have only one warehouse in Karachi. This warehouse manages all the problems when a problem comes. They ship the part based on the customer use case and customer service request. That is the only reason I rate it 8.5 because they have only one warehouse in Pakistan, which is in Karachi. For example, if a problem comes in Islamabad, it will take time to deliver the spare because the part will be shipped from Karachi to Islamabad, which will take around maybe a day. Other OEMs have their warehouses in Islamabad, Lahore, and Karachi also. In terms of part replacement requirements, they are very efficient in that area because they have warehouses in multiple cities of Pakistan.

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…
