1.4 System Capacity
System Capacity
For project engineering purposes it is necessary to estimate both the RAM-requirements
and the disk drive requirements of the system.
RAM:
available RAM Basic RAM on E2H081 processor board = 2MBytes
- this may be extended in 2MByte blocks up to a max. of 14MBytes
system requirements System itself requires approx. 1MByte
site data requirements Site data requirements may be estimated from the following:
- node 250 Bytes
- intervention text 750 Bytes
- picture 5000 Bytes
- MF-entry 64 Bytes
Example: The following system could be realised with only 2 additional RAM blocks
(total RAM = 6MBytes)
- no. of nodes 8000
- no. of intervention texts 1000
- no. of pictures 300
- no. of MF-entries 200
Disk space:
available disk space a HD-floppy disk has a capacity of 1.44MBytes
a hard disk with 32 MBytes of addressable memory may be employed in a MT7023 or
MT7033 system
system requirements System programs require approx. 700kBytes
site data requirements Site data requirements may be estimated from the following:
- node 60 Bytes
- intervention text 750 Bytes
- picture 4500 Bytes
- dynamic symbol 16 Bytes
- MF-entry 175 Bytes
Example: The following system could be realised with a single 1.44MB floppy disk
- no. of nodes 1000
- no. of intervention texts 100
- no. of pictures 50
1)
- no. of MF-entries 200
