I'm trying to find more details about a 160 TB storage server I'm using. When I run the command `lsblk`, I get the following output: `sdc 8:32 0 160.1T 0 disk /data`. In the out-of-band management tool, I see ten entries that look like this: `SCSI_Target1_LUN0 N/A WDC NA WUH722222AL5204 C7C0 Unencrypted HDD Enabled 0`. After researching the part number WUH722222AL5204, I discovered that these are 22TB hard drives. However, I'm unsure how to monitor their health, especially since we're using ASUS servers with ASMB11-iKVM IPMI. Any suggestions?

It looks like you might have a RAID controller in play here. Depending on the specific model, the commands you use might differ a bit. Try running `lspci | grep RAID` to identify your RAID controller. You may need to install some vendor-specific software for more detailed monitoring—like MegaCLI if you have a Broadcom LSI MegaRAID setup.
You might want to check out SNMP for monitoring. Your IPMI or RAID card should expose some monitoring data. Doing a bit of googling can lead you to download MIBs for your RAID controller or IPMI which can give you insights on the metrics you can scrape. Many IPMI interfaces allow you to set up SMTP notifications too, so it's a good idea to have multiple monitoring methods in place, just in case one fails. You wouldn’t want to miss a notification due to an expired password on your SMTP relay.
If you're running 10 of those 22TB drives in a RAID6 with a hot spare, that setup will indeed get you close to 160TB! Just make sure you have backups and monitor health regularly.
Thanks! I ran the command and this is what I got: `01:00.0 RAID bus controller: Broadcom / LSI MegaRAID 12GSAS/PCIe Secure SAS39xx`. So I guess I’ll need to install MegaCLI. Found the docs here: [Broadcom Docs](https://docs.broadcom.com/docs/12351583).
