Recommended Hardware for BIM Server

by István Moharos · updated: 03.20.2017

The following chart contains example specifications for BIM Server setups based on the number of active users. Note that the load on a BIM Server does not only depend on this, but also on other factors, such as the size of the projects, usage characteristics or network bandwidth. If you need further help in choosing your hardware for BIM Server get in touch with your local GRAPHISOFT reseller.

System requirements: BIM Server 20, BIM Server 19, BIM Server 18

CPU

64-bit CPU with 4 cores or more is recommended.

RAM

8 GB RAM for BIM Server is strongly recommended. For servers having a high number of active users and projects, consider 16 GB or more RAM.

As a more specific calculation, use 2 GB plus 1.5 times as much RAM as the actively used projects’ size, which is approximately 4.5 times larger than a PLN (and actively used means used at the same time by Teamwork users). For example, if there is a 1 GB and two 3 GB size projects which are used on the same BIM Server actively at the same time, then 2 + 1.5 x (1 + 2 x 3) = 12.5 >>> 16 GB RAM is recommended.

Storage

For BIM Server this is the most important factor, because the operations of the application are highly I/O intensive, which means the BIM Server has to read and write many database files at the same time really fast. Consider using the fastest possible storage (SSD, RAID solutions etc.).

5 GB free disk space is required for the installation and 10 GB or more is required per active project. Maintain 100 GB of free space for standard operation.

Make sure that the disk meets the following conditions:

  • Minimum 100 MB/s read AND write speed. For example, 7200 rpm HDD is the minimum.
  • If the database files (projects, libraries, BlobCache) are stored on a separated disk then the above mentioned speed must be able to handled by the connecting cable. For example, if the disk is an external disk which is connected with a common 1 Gbit Ethernet cable, it can handle circa 125 MB/s. Divided it into two parts (read+write) means the cable can handle 62 MB/s read and write speed maximum, which is NOT enough for the proper operation of BIM Server.
  • The disk must be started and mounted before BIM Server starts.
  • In case of external disks, the disk must have an own power supply. For example, getting power through an USB cable is NOT recommended.
