[VMWare] ESXi 호스트의 Memory 정보

Linux에서는 dmidecode 와 같은 툴로 쉽게 Memory 정보 확인이 가능하지만 VMware ESXi 에는 없다.

ESXi 호스트의 슬롯에 장착된 RAM의 양은 호스트로 ssh 접속 후 smbios 명령을 수행하면 아래 정보 확인이 가능하다.

 

# smbiosDump |grep -A 4 'Physical Memory Array'

sample output below Physical Memory Array: #4096 Use: 0x03 (System memory) Location: 0x03 (Motherboard) Slots: 24 Max. Size: 1536 GB   This shows that 24 slots and a total of 1536 GB of memory can be installed. So this server can be filled with 24x64GB sticks of memory.   Secondly which slots have memory installed, along with type and size.

# smbiosDump |grep -A 24 'Memory Device'
