What configuration to choose for the 1c + office server for video surveillance?

Question

1C

Hello.
The task is to assemble a server with high fault tolerance to work with the 1C Trade Management + database for video surveillance.
File base, about 4GB, simultaneous work of 4-5 users through terminal access. The number of cameras is from 5 to 10.
The emphasis on high fault tolerance is made because the whole thing needs to be assembled in another city "once and for all", i.e. so that most of the problems that arise can be solved remotely.
I would be grateful for recommendations on hardware, cameras, as well as advice on the overall organization of the infrastructure of a small office. In general, there is little experience, but I want to do it well, I ask for help.

Answer 1

Under video surveillance, put the Recorder, cameras to it. Most often it is bought as a set.
And under 1C, choose a server, there are a lot of articles and tests in Google, so you can choose the characteristics according to your needs.

Answer 2

1C and video surveillance are services that are completely different in terms of criticality. If either trade or a warehouse is tied to 1C, then fault tolerance must be ensured precisely by it. It depends on whether 1C works or not - whether the sale / shipment will go or not.
Video surveillance, on the other hand, is a "thing in itself", which fits well with hardware solutions (the same k-guard or adequate analogues) - once, and when installed on custom hardware, it requires maintenance (the same Windows updates), which is completely unnecessary for the task which will never develop. At the same time, this "thing in itself" eats a lot of resources and, becoming more complicated (being installed on Windows, for example), is finicky and less stable.

Answer 3

A video stream is a sequential write to disk.
Working with 1C is a mixture of random writing and random reading.
The disk subsystems must be different.
For video, buy a recorder with RJ-45 - search the relevant forums. The software must be correct. And then they only work through IE 6-7.
For a 1C failover cluster, you need 2 servers + storage. This is if the downtime is not more than 10 minutes, for example.
If there are several hours left to raise the server and the loss of user work in the database during this time is not critical, then you can do without storage and backups (for example, once an hour)

Answer 4

For cameras I use NUUO. 30-IP cameras with built-in motion detection load 1 xeon E5405 by about 30%. The program itself is even nothing, not resource-intensive, a huge list of supported cameras, there are free client applications for iPhones, etc., although the legal version costs money.
But they lied about sequential writing to disk - how many IP cameras, so many streams. Although you can of course merge the stream into 1, but I can imagine how much it will eat resources. Tried to defragment a stream on the fly - bad business. Even offline defragmentation of 2Tb disks (for me they work in pairs and alternate as they fill up) takes more than a day, so I decided not to torture them but leave them as they are - defragmentation is always 100%.
Under the video surveillance system, an HP ML370 G6 server is used (I took a second-hand one at an inexpensive price). Given that you can stick 2 or even 3 baskets of 8 SFF or 6 LFF disks, 2 Xeon X5690 processors, almost 300 gigabytes of memory, I think such a server will take out 1C with 50 users and video surveillance at the same time, especially that initially the server can be taken with the 1st processor and one basket, and then to increase as required.
Considering what omn in 90% of cases are SSD disks for workstations (and you are unlikely to pull server disks), then you need to use SAS for the database, preferably from HKL. If at the same time there is a normal RAID with a write cache and BBU (or better FBWC), then the performance difference between SSD and SAS with up to 10 users will not see 100%, it does not matter what kind of RAID, at least a mirror, at least 5 th. RAID-6 approached me.
