Minimum memory requirements for Symantec Encryption Management Server
CentOS 7.x requires at least 1 GB of RAM per logical CPU. For example, a Symantec Encryption Management Server with 4 logical CPUs would require a minimum of 4 GB of RAM to function properly. At least 4 GB of RAM is required to ensure proper performance for a single Symantec Encryption Management Server, and at least 8 GB of RAM if you plan to set up a server cluster.
Note
: Red Hat defines a logical CPU as any schedulable entity. So every core/thread in a multicore/thread processor is a logical CPU.
Note
: Symantec Encryption Management Server 3.4.2 was based on CentOS 6. Security updates for CentOS 6 ended in November 2020. Therefore, administrators managing the 3.4.x version of Symantec Encryption Management Server should upgrade to Symantec Encryption Management Server 10.5 or above as soon as possible because it is based on CentOS 7.
