Do you need Storage Spaces in a small system?

Question

Windows

A server is planned for 50 terminal users and a medium-sized 1C file base. Selected iron DELL R710. The main work of users is browsers, 1C, instant messengers and file storage (sales managers). The base system will be Windows Server 2012, possibly HV.
The client suggests using 2xHDD in the mirror + 1xSSD for cache, I suggest using 2xHDD in the mirror + 2xSSD in the mirror. OS and DB on SSD, the rest on HDD.
Link to SS test charts, but I think it's wrong to compare large arrays of 12 HDDs with the current situation.

Does anyone have experience or any thoughts on the topic?

Answer 1

Please note that it is not possible to install or download Windows from the Storage Spaces pool (at least on Windows Server 2012/2012R2).
If the performance of the HDD is sufficient for the tasks that will be assigned to them, this is the most economical option. To use SS, you will need a separate disk / array of disks under the OS.
Tiered Storage Spaces requires a minimum of 2 SSDs if you plan to somehow protect against drive failures. With a single SSD, you can only create a Simple Pool (similar to RAID0 / JBOD).
With the performance of tiered Storage Spaces, everything is very good: all recording always goes to SSD, reading comes from where it comes from. By default, SS optimization (moving hot/cold data to the corresponding tiers) is performed once a day, but you can also start it manually with the command

Get-ScheduledTask -TaskName "Storage Tiers Optimization" | Start-ScheduledTask

If SS is planned correctly (SSD size is greater than or equal to the number of hot data), you will not notice performance problems.
PS Let me share my experience: I have a ghetto-storage for virtualization of a couple of small servers approximately your task profile. Used just tiered Storage Spaces, 2 x Intel s3500 + 4 x desktop HDD. No problems for over a year.

Answer 2

A server is planned for 50 terminal users and a medium-sized 1C file base

Filebase for 50 users? Are you joking? Or will two or three people work with her?
First you need to know how many people will sit in 1s, what configuration and size of the database.
Since the terminal, it is clear that all user profiles, the swap file and the pace must be on the SSD, and the system can be heaped.
For the rest, in principle, the HDD will do, but again, it is better to spread the file base and file storage on different disks.
And security will have to be hard-wired, otherwise someone will catch the encryptor and the server will get up, and you will lose the data.

Answer 3

Why not just 4 SSDs? Obviously it's a hundred times better.
