See below for the PKI DB Appliance machine requirements.

Required number of CPUs 

PKI DB Appliance requires at least 4 CPUs.

Required RAM memory

PKI DB Appliance requires at least 16 GB of RAM memory.

Database storage

To calculate the required disk space, add 65 GB to the disk size required by each deployment solution. 

Solution

Number of managed certificates

Size

Certificate Authority

100,000

~1,500 MB

Certificate Enrollment Gateway

100,000

TBD 

Certificate Manager

100,000

~350 MB

Validation Authority

100,000

~75 MB

Storage data are approximate, as the size of each certificate depends on factors such as the certificate algorithm and extensions.

Maximum tested capacity

PKI Hub has been tested with databases containing up to 1 million certificates.
