Selecting a server to work in terminal mode with 1C?

Question

VMware

Good evening everyone!
The task was to virtualize the terminal (iron) server 1C on a dedicated hosting.
Current server config:

Processor: 2x QuadCore Intel Xeon E5620, 2400 MHz
Memory: 32GB RAM DDR3 1333MHz
Disk subsystem: Smart Array P410 Controller, RAID10, 6xSAS 600GB.
OS: Windows Server 2003 R2 Standart
Soft: MS SQL 2005, 1C Enterprise v8.2, number of concurrent users <= 50, 1C database size about 20GB.

Task: to select an iron dedicated server that can handle such a load under the following conditions:

1. VMware ESXi will be installed on the new server, inside which there will be a virtual machine with Windows Server 2012 R2, MS SQL 2008, 1C v8.3
2. It is possible to increase the number of simultaneous users up to 60 people. You need to have a supply of resources.
3. On the same ESXi, a VM with Linux on board will be running as a VPN server for these 1C employees.

At the moment, in the hour of the greatest load on the current server, about 16GB of RAM and about 30-40% of the processor resources are "eaten away", judging by the task manager and the performance monitor.

Ordering the same server by configuration is not a problem, but I want to save money if possible. All two-processor servers for rent start from 300 euros / month, which is not very budgetary. Similar configurations with the same memory, disk subsystem, but with one processor, say, the Intel® Core™ i7-4770 (the most common processor among hosters at the moment) are much cheaper.

And now the question is whether it is possible to somehow make sure in advance that the above configuration will work fine on this Intel® Core™ i7-4770 processor or not. What measurements on the current server need to be done to give such a forecast? Thank you.

Answer 1

Not as an advertisement, but simply as an advice - nforce.com - host servers in different Dutch data centers. The cost of Dedicated servers is very pleasant. Platforms are mainly HP Prolian with super flexible customization - you can choose the number and type of disks yourself, you can deliver separate RAID controllers or PCI-ex SSD boards.

Theoretically, at the same load, the i7-4770 will pull out + 25-30%, if you look at the tests in parrots.
Platform difference. Two-socket configurations are at least slightly server-oriented. Single-socket - sometimes this is really the cheapest iron stuffed into a thin case. Which in principle is not a serious minus. That's just on such hardware is definitely softraid. Accordingly - how will you implement the minimum fault tolerance if you install esxi?
With so many users, if I were a manager, I would definitely demand fault tolerance or system recovery with a downtime of no more than 15 minutes. If you take a server with small SSDs, they may already be well used.
With an employee cost of $1,000 per month, the cost of an hour of downtime will be (60*1,000)/160 = $375, not counting lost profits. Those. monthly savings are offset by one incident.
