    The performance of IBM FlashSystem is very good. The new technology and high throughput have given us more confidence in the solution. The management of the system has improved and we can control the monitoring system alerts and multiple FlashSystems with the Enterprise Cloud Edition, which is free. The migration of recently stored data to a new flash is much easier. You can move your data because you can utilize it externally.

    PowerScale allows us to manage storage without managing RAID groups or migrating volumes between controllers. It has really simplified things. We're not having to worry about the underlying infrastructure. That takes care of itself. We just worry about the data. It's really easy for deploying and managing storage at the petabyte scale.

    We use Nasuni's continuous file versioning feature and it fully protects us. With the ability to version files and have continuous recovery, it helps in terms of resiliency. If we have an incident then we would be able to easily recover from it by using the technology.
  7. They call us when monitoring shows a possible issue and are very flexible in working with our schedule to troubleshoot when it is convenient for us. Having instant failover redundancy helps me sleep easier at night.

What does a storage engineer take into account when deciding between NAS or SAN storage?

NAS: cheaper, slower to access, easier to manage
SAN: more expensive, fast access, needs specialist management skillset.

SAN is generally used when you need lots of storage close to computing power.
NAS when you need storage shared by networked users.

There can be MANY things to be considered here, but it can also be simple. As with most IT infrastructure things, there are plenty of variables that might apply in some scenarios and not in others. Given the limited about of information we have to work with, I'd say it mostly boils down to a few things:
(1) Is this data to be accessed and manipulated by a human user, or by another computer (such as an application server or data base server).
(2) Are the files in question large files that are sequentially accessed (video, audio, etc) or are they "small-block RANDOM" in nature - or is it a mix?
(3) Do you have specific network constraints between the storage and the systems accessing it?

Depending on Requirements & what workload defined for NAS vs SAN
NAS - Fabric -tcp/ip- File Level -Performance - lower -Scalability - limited -Manageability - easier to manage - Price - less
SAN- Fabric -FC Networks - Block Level -Performance - Higher -Scalability - scale up-scale -out -Manageability - more complex to manage Price -More expensive

First, we should define what we mean by SAN and NAS. The most common and general definition is: SAN is a stack of block access protocols and hardware, and NAS is file-level protocols. So, the choice depends on the task at hand. In my opinion, NAS is easier to manage and maintain if used for virtual machines datastores - NFS for VMware and xen and cifs for Hyper-v. File protocols are also good in sql server clustering (no need in middleware like iSCSI or costly FC SAN infrastructure). For now (end of 2020), file protocols also have faster access speed than FC (32Gb FC vs 100Gb Ethernet or even more via single link). File protocols also have an advantage if you run DECO on your storage - you don't need to run UNMAP on host, which doesn't work in some configurations and needs additional attention and administrator's time. On the other hand, block protocols (SAN) are mature, have a wide install base, and a huge amount of vendors are supported.

The type of usage has first to be taken into consideration.
Most work can be done on a NAS as disks have grown faster.
However, high performance DB should be on SAN.
In the longerterm, NAS can suffer as some users have the tendency to put DBs there because of the relative ease of use
