Pooled memory heartbeat in shared memory architecture

A computer system comprising:

• a memory device providing pooled memory accessible by a plurality of hosts, the pooled memory comprising at least one shared partition;
• a processor;
• and
• a non-transitory computer readable medium having stored thereon program code for monitoring pooled memory heartbeats to determine host status, the program code causing the processor to:
• check a heartbeat file stored in at least one shared partition on a pooled memory, the heartbeat file associated with a selected host in a plurality of host computing devices;
• on determining the checked heartbeat file is locked, identify a pooled memory heartbeat status of the selected host as an active pooled memory heartbeat;
• and
• on determining the checked heartbeat file is unlocked, identify the pooled memory heartbeat status as an inactive pooled memory heartbeat, the inactive pooled memory heartbeat indicates the selected host has lost connection to the pooled memory.

A non-transitory computer readable storage medium having stored thereon program code executable by a first computer system at a first site, the program code embodying a method comprising:

• checking a heartbeat file stored in at least one shared partition on a pooled memory, the heartbeat file associated with a selected host in a plurality of host computing devices;
• identifying a pooled memory heartbeat status of the selected host as an active pooled memory heartbeat, on determining the checked heartbeat file is locked;
• and
• identifying the pooled memory heartbeat status as an inactive pooled memory heartbeat on determining the pooled memory heartbeat file is unlocked, the inactive pooled memory heartbeat indicates the selected host has lost connection to the pooled memory.
