- Document the total installed memory and current usage.
- Check for any existing memory errors or alerts.
- Take note of the current memory module specifications.
- Refer to the server's hardware compatibility list.
- Cross-check memory specifications against the new modules.
- Ensure the memory type (e.g., DDR4) matches.
- Verify the speed (MHz) is supported by the server.
- Confirm the number of channels and capacity limits.
- Consult the server's technical documentation.
- Identify the maximum memory limit for the motherboard.
- Check for any firmware updates that may affect capacity.
- Document any limitations based on current memory configuration.
- Ensure planned upgrades do not exceed this limit.
- Purchase memory modules from a reputable vendor.
- Ensure modules match specifications from compatibility list.
- Keep receipts and warranty information for the modules.
- Check for any return policies or guarantees.
- Verify the delivery date aligns with upgrade schedule.
- Create a full backup of the ESXi host settings.
- Export virtual machine configurations and data.
- Store backups in a secure, separate location.
- Verify integrity of backup files.
- Document backup procedures and locations.
- Check the current ESXi version through the management interface.
- Refer to VMware's compatibility guides for memory support.
- Plan for any required upgrades to ESXi version.
- Document version history and upgrade paths.
- Schedule time for any necessary version upgrades.
- Access the performance monitoring tools in ESXi.
- Review memory usage statistics and performance graphs.
- Identify any alerts or warnings related to memory.
