Hello,
I read hardware requirements and I wonder If I get it right ( Technical Specification)
CPU: Number of Concurrent Connections per core (con./core)
This tells us how many connections our computer’s processor (CPU) can handle at the same time per core:
- For RDP/SSH, one CPU core can handle 300 connections at once.
- For Web, one CPU core can handle 30 connections at once.
RAM: Amount of memory used per connection (MB/con.)
This tells us how much RAM is used for each connection:
- For RDP/SSH, each connection uses 20 MB of RAM.
- For Web, each connection uses 40 MB of RAM.
HDD: Disk space by time per connection (kB/s/con.)
This tells us how much disk space is used over time for each connection:
- For RDP/SSH, each connection uses 3 kilobytes per second.
- For Web, each connection uses 4 kilobytes per second.
===============================================
So hardware requirements—CPU, RAM, and HDD capacity—for the scenario with 500 RDP/SSH sessions, operating 8 hours per day, 5 days a week, and a 3-month retention period.
1. CPU Requirements
RDP/SSH:
- Connections: 500
- Connections per core: 300
- Required cores: 500300=1.67≈2\frac{500}{300} = 1.67 \approx 2300500=1.67≈2 cores
2. RAM Requirements
RDP/SSH:
- Connections: 500
- RAM per connection: 20 MB
- Total RAM: 500×20=10000500 \times 20 = 10000500×20=10000 MB = 10 GB
3. HDD Capacity
- Determine the total data generated per second:
- RDP/SSH: 500 connections * 3 kB/s = 1500 kB/s
- Convert kB/s to MB/s:
- 1500 kB/s ÷ 1024 = 1.46 MB/s
- Calculate data generated per hour:
- 1.46 MB/s * 60 seconds/minute * 60 minutes/hour = 5256 MB/hour ≈ 5.13 GB/hour
- Calculate data generated per day (8 hours):
- 5.13 GB/hour * 8 hours/day = 41.04 GB/day
- Calculate data generated per week (5 days):
- 41.04 GB/day * 5 days/week = 205.2 GB/week
- Calculate data generated per month:
- Assuming 4 weeks per month: 205.2 GB/week * 4 weeks/month = 820.8 GB/month ≈ 0.80 TB/month
- Calculate total data for a 3-month retention period:
- Total HDD capacity: 0.80 TB/month * 3 months = 2.4 TB
Summary
For 500 RDP/SSH sessions, operating 8 hours per day, 5 days a week, with a 3-month retention period, the hardware requirements are:
- CPU: 2 cores
- RAM: 10 GB
- HDD Capacity: 2.4 TB
