Popular Comparisons It's very fast and very easy to use. It performs well and is both flexible and compatible. We like it because it's easy to use.
At this point, I don't know anything that they could provide in a better way.
Popular Comparisons Technical support is good.
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.
Popular Comparisons Integration is easy with this product.
This solution makes it easy to manage storage, provision new workloads, and scale-up.
Popular Comparisons The features which are most valuable are the availability of the system and the management.
The speed is very good.
Popular Comparisons The deduplication and compression capabilities are powerful.
Good architecture and produces a lot of IOPS.
Popular Comparisons The power systems are very reliable if you are running 24/7 operations. For ongoing mission-critical applications, it's the best solution.
I like most of the features. Its speed, performance, and availability are valuable. We are implementing the data reduction technology the most.
Popular Comparisons The most valuable features are the Metro clustering, and disaster recovery.
It's very easy-to-use.
Popular Comparisons One time, we had a drive fail and we were notified before we even saw it on the device.
They have a feature called Live Migrate; it's been very, very useful.

How do thick and thin provisioning affect all-flash storage array performance? What are the relative benefits of each?
What is All-Flash Storage Arrays?
The all flash storage array has matured to the point where it is now powering much of the growth in the enterprise storage business. Advances in the design, performance and management capabilities of solid state drive (SSDs), coupled with declines in cost, make flash storage viable for many workloads. The category includes NAND flash, SSD SATA, tiered storage and NAND flash memory. Enterprise storage is relentlessly demanding, though, so potential buyers need to think critically about what makes the best choice of flash array.
IT Central Station members who have experience with solid state storage emphasize ease of use as an essential selection criterion. They suggest asking if daily and weekly tasks can be completed easily. For example, how difficult is it to add or change storage volumes and logical unit numbers (LUNs)?
Some popular user comparisons:
Performance also matters, though many members comment that virtually all flash drives offer strong performance. Look closely at (IOPS), reduced footprint and lower power usage. In addition, they suggest asking whether one needs an array with larger block size and one where compression and de-duplication can be enabled or disabled on select volumes. But, reviewers add, it’s important to understand one’s data. For example, with an Oracle database, block size will matter a great deal.
Data reduction and data management capabilities factor into many comments about solid state hard drive selection. Deduplication and compression help manage storage growth. Reviewers also point out that recovery abilities matter with solid state drives. No one wants data loss if the storage array powers down suddenly.
Data storage companies offer many different reporting options. IT Central Station members stress the importance of this feature. For instance, do reports show the business the efficiencies provided by the storage infrastructure? Or, do they report on the specifics of data compression, de-duplication rates, I/O Latency reports and so forth.

It has better performance than Hybrid storage and customers can have more IOPS,
for the mission critical application customers better use all-flash arrayas
Speed (IOPs), increased reliability, compactness.
If your application does not needs those you can go with legacy solutions as far as price justifies.
Sooner or later even price will be in favour of all-flash
In general, all-flash arrays have much better price/performance (in case if turning on DECO is not slowing down the array - some vendors have this issue, so PoC is needed) than hdd-only or hybrid arrays. Higher performance, lower power consumption per TB. The support cost for the HDD-only and hybrid arrays will be more an more expensive, as the HDDs share is going lower, and the main R&D is moved to all-flash arrays. Of course, in some cases (i.e. video surveillance, D2D and maybe several others), HDD-only arrays are the better option, so it's better to make a decision case-by-case.
It all depends on the Budget as well....if required High IOPs for Database or other read/write intensive services and also budget is not a issue then go for All Flash...Otherwise combining SSD with NL-SAS alongwith tiering / cache features will suffice purpose in most conditions...
The selection of All-Flash Storage Solutions depends on requirements and the goal any customer is looking to achieve at the end.
All-Flash is not a fit for all requirements......
"If a customer needs a storage solution with high to extreme performance,
Rack-space
efficient, power and cooling efficient (environmentally friendly),
build-in compression; then they should choose All-Flash solutions."
It is not all about the performance that storage manufacturers are very aggressive to sell their All-Flash boxes.
Just think about SAS disks..... those were used as performance and SATA as capacity.
Enterprise SAS disk technology is limited to 1.8TB/disk only; that is why storage manufacturers are promoting their All-Flash to fill the capacity gap created because of SAS disks technology limitations.
The modern Flash disks are covering both requirements (Capacity+Performance) but are still expensive (if we assume the same RAW capacity).
If a customer comes with the requirements that fits to an Enterprise Hybrid Storage solution like 40%SSD, 30%SAS and 30%SATA; 400TB RAW in total, then they should select All-Flash instead, as both solutions will not have any significant cost differences.
If a customer's requirements (Performance+Capacity+Cost-effective) fits to SAS then they should choose a SAS based storage solution.
If a customer needs an archival storage then they should choose SATA based solutions.
If a customer needs a storage solution with high to extreme performance, Rack-space, power and cooling efficient (environmentally friendly), build-in compression, then they should choose All-Flash solutions.
If customer needs less SSDs/Flash disks; like.... 10%SSD+45%SAS+45%SATA, then Hybrid type of storage solutions will be a good and cost-effective option.
All-flash arrays are more costlier than any other storage arrays.
Will give more performance with less latency when compared to any other arrays
