Keep in mind even big shops when they talk about clustering for file servers it is for failover, not load balancing.what setup do you suggest to create a failover backup cluster?
lets say i want to connect to the 2 on site servers with one connection or one path , an if one is down the second is up with the same data on itStarwind will probably work for this, in fact I had a failover cluster at work using Starwind few years ago, it wasn't worth it. Power loss was the weak point, Starwind had to sync storage after both nodes went down, so we were talking about 3-4 hours of downtime each time power went out for long enough to drain UPSes, no generators unfortunately. We had to spend additional few thousand on bigger UPS units.
So do the math, if the server goes down, would the business lose so much money to justify buying 2nd server? And probably more equipment (UPS, etc.) You can have 4 hour onsite service, Dell I think even offers 2 hours onsite, so best case you could be up and running in 3-4 hours in case of a server failure.
If you plan on going with 10gbit network, you really should be looking at SSD disks, spinning rust will have a hard time saturating that, probably 8-10 disks at minimum.

@Pete-S , thanks for the 12tb suggestion, but i want performance too if i went for 10gb lan
and unfortunately, i couldn't find any 3.5 servers except these 2, r710, r510If you're looking for servers with more 3.5" bay capability, have a look at Supermicro. They have a lot of different servers and sizes - many of them with 3.5" bays.
They also have JBOD chassis which means you can take any standard 1U/2U server, put in a raid card that has external SAS ports and hook it up to the JBOD chassis. That way you can hook up how ever many disks you want to a simple 1U server.

Dell 530 - 8x3.5
Dell 730 - 8x2.5
Dell 730xd - 12x3.5 + 4 non-hot swap 3.5There are plenty of other options. I would definitely check out xbyte. They might even have a precofigured 720xd "special" to your liking.

xbyte normally only ships to the U.S., which @GodfatherX64 isn't in from what we can tell here.

@scottalanmiller , WD Gold, OBR10 for performance, fedora (vm) with xfs maybe,
That would be your best speed and reliability, yes. And definitely XFS.

For other workloads, like databases, you want the application to handle it.

info for all : i live in Egypt
@marcinozga , thanks for your suggestion , i'm starting to think about one big server instead of two.
@Pete-S , unfortunately, supermicro is not available here and the shipping cost for a new server is massive.
@dave_c , the cost to buy something from outside the country is tough, we cant do that right now.
@bnrstnr , the r510 is the only server i can find here with 3.5 slots, either that or older,
and we can't import from outside the country these days. -

That is nearly always the better choice. It varies by region, company, task, etc. BUT...
Generally the cost of doubling the hardware is high, while the cost of downtime is low. People perceive it the opposite, and sometimes it is, but most often it is the better business decision not to have failover. Even huge investment banks rarely do that for workloads.

To ask the question, what qualifies as a " 'proper' storage server" to you?
Windows, Linux, FreeBSD, Solaris?
Physical or virtual (everyone here would recommend virtual).

@scottalanmiller , thanks
instead of the hypervizor failover, what do you suggest for a sync service in linux to just copy the differtintals between files, what do you think about rsync, would it be adequate than the hypervisor

RSync works quite well.

@DustinB3403 , is this question for me?
if it is, to me a proper storage server would be an enterprise server hardware with a stable server os, physical or virtual (i too prefer virtual), with a lot of storage features :D, and a scalable storage system for future expansion -

Dell of course is another option, which you don't seem to have any issues getting.
Storage features being? Scalable storage has already been discussed in this topic.

Indeed, StarWind could do a great job in case of clustering required for this environment.
With Ceph it could be a tough job to make it work properly, especially in terms of the amount of time spent on that. -

@scottalanmiller there's also the purple series, they are pretty much on par with the reds

In theory they are intended for special cases like video recording.

Yup, pretty much the same thing - intended for always-on, without too much heavy IO. Frankly, I doubt there's anything significantly different under the hood there.
