HPE 3PAR StoreServ is a great storage device for both file and block-level storage needs. You can use it in place of SAN devices required by database servers. It provides an amazing compaction ratio and, hence, reduces overall storage footprint and cost. This is, however, slightly costly if your environment doesn't really see high transactions most of the time.
If you have one user or 1000's of users (especially using Windows), Windows Server is a no-brainer! The only reason I would suggest going with a Linux server is if you have old hardware (Windows Server is more process intensive than Linux). But, Linux is open-source, so anyone can publish updates/security updates, but on the flip side, malicious people also have full access to Linux's codebase allowing for much easier writing of exploitations/viruses/malware/ransomware.
We are using HP 3PAR storeServ 8200 for both our file level and block level storage.
I really love the amazing compaction ratio provided by HP 3PAR. Some of our disks have compaction ratio above 25:1, which is super amazing. You can definitely look for around 75% reduction of storage footprints.
It has a great user friendly web console "SSMC"(StoreServ Management Console). This is an additional bonus and can be used by even non-storage people like DBA and Network to take a look at storage performance.
The system requires a physical or virtual system to manage upgrades and patches and for call home features. Most other systems have this integrated into the array. Just another piece of infrastructure to manage.
There are some system jobs that come pre-scheduled in the initial setup, but there is at least 1 job that should be added to this by default. When you delete storage, you also need to run a job to compact the CPG (a group where the luns all reside) to reclaim the previously used storage as free. This should be done by default at least monthly in the background.
There are 2 different GUI front ends that can still be used. The older version (3 PAR management console) is being phased out (has been for 3 years).
DHCP Server could be better - we use the router for DHCP Routing
Print Server - not a fan of using the server as a print server since you have to license it. Direct access to printers via IP addresses is a much more efficient way to go
Better backup program - we utilize a third-party program that gives us more flexibility when restoring individual files.
We are very satisfied with 3PAR performance and especially the IOPS (Input Output Per Second) is pretty amazing. It is easy to configure and doesn't require much knowledge of storage for Tier 1 support team.
I've carefully reviewed the servers and services currently running on Windows Server 2012, and given the opportunity would renew them as is going forward. There are two systems I currently have in place, one is a very large Linux implementation for a large ecommerce site, and one is a very large backup solution front ended by FTP servers running Linux. Neither are well suited for Windows, but the overall network infrastructure is and will be Windows Server for the foreseeable future.
There are simply too many different parts of Windows Server to make it a cohesive piece of software. While some of the newer features found in Windows Server 2012 and 2016 have nice UIs that are logically laid out, there are enough parts of the system that is still based on old code with clunky UIs and confusing options to make Windows Server a particularly user-friendly experience.
With their phone home technology, we usually have a replacement part on its way by the time we wake up in the morning, or if the event occurs overnight. We have had great support when we had questions or events that required a call.
Microsoft's support is hugely wide-ranging from articles online to having to contact them directly for the more serious issues. In recent years when I have contacted them directly, I have found the support o be excellent as I have found myself connected to very knowledgeable people in the field in which I needed the support. The online support available is vast and I tend to find most of the time that there is always someone out there who has had the same issue as me in the past and knows something about how to resolve it! This is the advantage of using industry standard and long-established systems such as Windows Server.
Make sure that you have detailed processes in place for every server instance you plan to install/upgrade, if possible get the base OS loaded and Windows Updates applied ahead of time, and if using a VM take a snapshot prior to installing each role, as well as along the way.
We still use NetApp storage enclosures at each plant for our routine file shares (CIFS) but I would love to swap them out for the HPE 3PARs as we use for our ERP app data. The 3PARS are simply faster and much better at near-instant replication. But even more importantly we can get the reporting that we need from the 3PAR within a few minutes, even custom reports. 3PARs are much easier to manage than NetApps in general and I think that the only place that they compete is in compaction.
I didn't use any other system which gives the same functionality and I am not aware of any. The full integration between all components and especially the ability to integrate mail via Exchange or even via a hybrid setup with the Ofice365 cloud, including the ability to directly manage the cloud from the server, using Power Shell, is something I didn't see anywhere else.
Because of our Microsoft Campus Agreement, Windows products are fairly affordable for us and that has been a huge blessing. We are considering some Azure cloud options and some of that is covered under our Campus Agreement, making it a nice incentive to start migrating certain apps and functionality to the cloud
I don't have access to our budgets so I cannot give a good answer as far as the impact of ROI on our institution, but if your company can afford it, you cannot go wrong with Windows server. Not having to send your sys admins to Linux or Unix school alone is a big savings as well as not having to train your staff on using a Linux desktop instead of a Windows-based one.
The compatibility with end users of all varieties and platforms will definitely impact your ROI in a positive way. We have Apple users, Android, Windows, and even a few Linux end users on our campus and Windows server works quite well with all of them.
