How to organize storage for a home server?

Question

Iron

Good day to all!
I decided to upgrade my servers, or rather put everything on 1, I plan to take a Supermicro 6025T and run virtual machines on it with the necessary roles in Hyper-V. It is planned to use a large disk space (For home archive storage; backups of various databases, VMs, agent data from a PC; a small file storage; application servers. All this will be spinning on VMs. It takes about 10 TB of space and will grow, + all this in RAID ). And when studying the issue of storage systems, I ran into a dead end.
And so, questions: is
storage better ready-made or assemble it yourself? For example, using ESOS (Article https://blog.it-kb.ru/2018/07/25/using-the-old-ibm...
fiber channel, iscsi? Or are there any other protocols?
Have you had experience building a storage system at home and what problems did you have?
What is the best literature to read on this subject?
Budget for storage + disks + -100,000 rubles.
Thanks in advance for your replies!

Answer 1

Attention to the question: what for do you need storage?
Moreover, we are talking about a 2U chassis already for 8 hotswap disks for only 10TB of space - up to 112TB of raw capacity for modern disks.

Answer 2

Budget for storage + disks + -100,000 rubles

For such money, only the storage systems themselves, disks for the required volume, another 50% -100% of the initial amount. At this price, it will be a piece of iron without duplication, which is still weakly drawn to the level of storage systems.
Apparently, we don’t need industrial-level storage, but just a cool NAS.
I can recommend the following method:
a computer is purchased under the "server". Emphasis is placed on the processor (faster - better), memory (more - better) (ESS), disks. When choosing disks, you need to strike a balance between speed, reliability, and volume.
two flash drives of 4GB are purchased. Nas4Free is installed
on the received hardware, the system is installed on a flash drive, and a zfs array is raised on the disks.
You make pools, cut moons of the required volumes into them.
And further on iscsi you give all this economy to the hypervisor.
Keep within the specified amount, solve the tasks.
ZFS is not as scary as it seems, well, data backups to an external small nas on raid1 will not hurt.

Answer 3

What kind of RAID do you need?

Answer 4

Colleagues are correct.
SHD is a specific equipment, and quite expensive. You can't buy it for 25 thousand rubles :-) If you take a CU, then firstly, it will already be removed from support, and hence the slightest sneeze of equipment, and the whole system turns into a pumpkin. Secondly, you can’t stick any disks in the storage system. Only those that were produced specifically for this storage system. It is expensive, and most likely you will not find it for used systems. Ordinary arbitrary disks, even enterprise grade, will not work in storage systems.
Among all other considerations, think about where to put it and how to connect it. Because industrial storage systems are quite large, noisy and consume electricity in order.
So if you are not satisfied with the all-in-one system, and you definitely want to move storage to a separate piece of hardware, then there is only self-assembly and software solutions. FreeNAS, ESOS, manually build all the same on Linux or FreeBSD - depending on your skills. Well, plus to this - then it makes no sense to take a 2U chassis with 8 bays for LFF drives, it's better to take a 1U server. It will cost less, take up less space, eat less electricity. Although noisier, of course. Like this .
Literature - documentation on the relevant software systems. You can also look at Nexenta. She, like FreeNAS, also works on a freighter. Previously, the free community edition was, however, with a volume limit. Now I don’t know how things are going there, I haven’t been interested in it for a long time.

Answer 5

Sorry, but why do you need storage systems here? If you are laying on the server case and on the hyper. Put as many drives as you like into the case, make RAID10. If you need backups, take a shelf like Synology / QNAP.
SHD, as Artem and athacker rightly noted , is a brand, a support. This is necessary when there is a lot of the same type of iron. BU iron - it can turn out to be quite cumbersome - here we have an Intel blade basket - a working one, equipped with disks, 4 blades, two xeons each. A box at least 8U high, eating energy like a mining farm :)

Answer 6

A vm is created which will be the storage, the controller is thrown into it (the disks on it will be thrown by themselves), nfs / iscsi rises on this vm and is given to the hypervisor as the main storage
