You should consider different perspectives for this question, performance, data reduction, price, management and usage.
In the Performance view you should consider All Flash Platforms for this value. HP 3Par, EMC, Netapp and Pure Storage All Flash arrays give you much more but I can put EMC and Pure Storage a bit infront as you can see from the last years All Flash Gartner Report.
For the data reduction perspective, again EMC and Pure Storage is far from the other vendors, altough Netapp started to use Data onTap 9.x for better reduction values, and HP announced compression algorithm in its new firmware but still with 512 KB data slicing and with double deduplication values Pure Storage gives minimum 3X-4X in virtual environments.
Price differentiate in a large scale at the regions.
Management and usage is not a big problem for a good storage admin, you always find the automation processes for all vendors.
Pure Flash Array,Its the best enterprise storage which I come across recent days,Its technology and performance are awsome.
Storage solution depends upon customer's requirement but Dell EMC Unity is best storage solution that fits every requirement of most customers by providing them high performance at low cost.
This is a type of questions that leads to many answers. But, the best will be: It depends on your case.
Generally: EMC, Hitachi, HP, and NetApp are leaders (alphabetically order; not technically), and are capable of meeting your demands.
To assist you limit your options, kindly take these points into consideration:
Your budget --> Although "All Flash Storage" will provide the best performance, it will be the highest in price. On the other hand, "All SATA Storage" will provide the least performance; yet with the least price.
your current storage vendor/family/model/firmware --> You may think of a migration and/or cascading the old and new boxes. So, you'll need assure that there is an upgrade path and/or a migration capability.
Your required latency --> All disks have latency in retrieving data. Some applications may stop responding when a certain delay is reached. So, assess your applications.
Envronment Type --> Will the box be for a Production or a Test environment, or just for Archiving old/stale data. The best configuration should go for a Production environment; unless your Test needs that so.
Virtualization --> Do you depend on Physical or Virtual ennvironment? Are you going into virtualization of the existing physical ones? Are you going to expand in either types? ... Virtualization is a "Storage Trap"! (Capacity Planning + Deduplication + Backup + Cloning) are key determinants.
Support --> Based on your country and the available Levels of Service Agreement with the vendor.
Replication --> If you consider so; Whether your replication will be within the same site or with a remote site (e.g. a DR one), you'll need examine the replication technique and its performance using the available connectivity links.
Management & Administration --> You'll need to check wih the vendors ther way of administering their resective boxes. Ease of use and availability of training/support are essential in a heavy workload environment.
Tiering --> If it will be a "General-Use Box", consider mixing the types of drives (e.g. Flash + SAS + SATA) and assign the appropriate type to the appropriate application/environment.
I hope this helps.
The best storage solution is the solution comply with your organization or company needs and wants, the brand is not the only matter; how to use the solution what design you use is much more matter than the brand, in some cases you don't need more than some external hard discs and in other cases you need a huge data center, I prefer the DellEMC solutions for the big data centers and there are various series in both storage and backup solution which got the number one based on Gartner annual report.
I think EMC storage or HP but this depend on what kind of storage do you need .
HP storage and Oracle FS Storage. You can choose EMC aswell
Thats a vague question, as it totally depends upon the requirement.
I agree that we should consider the best solution which complies to our organization and to consider all Flash Platforms.
Recently I had been through a POC with a technology called "Nutanix". This really surprised me a lot. This box is totally amazing which makes your Data center a software based platform, virtualization and storage is totally invisible, central dashboard for administrating and managing your entire environment.
As an IT Pro you think what could be the best possibilities for your organization, you will find your answers in it, from small till large businesses, you can scale easily whenever and however you need to, your new Data center can be up and running within an hour.
Installations, Upgrades and migrations with just few clicks, all hypervisor OS supported, recently they have build their own hypervisor called "Acropolis". Now they are making cloud invisible, for more details you can visit their website: https://www.nutanix.com/
EMC Storage is easy to mange also easy interface
