![]() System x RAID controller features and specifications summary Feature To enable RAID using non-Intel NVMe SSDs requires VROC Premium which is a Feature on Demand (FoD) license upgrade (part number 4L47A39164, feature code B96G) ‡ Intel VROC NVMe RAID supports Intel-branded NVMe SSDs without any additional license. Advanced hardware RAID controllers Feature RAID 940-16i 8GB Flash Internal Adapter.RAID 730-8i 1GB Cache (not available in USA or Canada).ThinkSystem M.2 with Mirroring Enablement Kit.Onboard NVMe RAID for Intel processor-based servers (Intel VROC NVMe RAID).Onboard SATA RAID for Intel processor-based servers (Intel VROC SATA RAID, formerly known as Intel RSTe).This guide introduces the RAID management tools and their capabilities, along with the links to download these tools and the respective user guides,for use on supported ThinkSystem, ThinkServer, and System x servers with the following RAID controllers: These tools enable Lenovo RAID controllers to be managed through a user interface or command line interface in the pre-boot environment, during the deployment of an operating system, and after the operating system is deployed. It’s no surprise that drives that get too hot or are otherwise stressed beyond normal limits tend to fail early.Lenovo offers a suite of management tools to simplify the configuration and management of the RAID controllers for ThinkSystem, ThinkServer, and System x servers. Smartctl also reports on things like drive temperature, how long the drive has been powered on, how many times it has been started and shut down etc. They point out that maybe a quarter of their drives fail when all these statistics are 0, so a healthy SMART report does not necessarily mean a healthy drive, but almost none of their drives survive having errors on all five counts. SMART 197 | Current Pending Sector Timeout |ī (who run huge raid arrays) have a lot of interesting information on their site. SMART 187 | Reported Uncorrectable Errors | ![]() stats that can be looked at which will provide clues: When you read the “When things go wrogn” section, you will see that smartctl is a very important diagnostic tool, but it also provides a lot of proactive information to help you anticipate a drive failure. ![]() This tool tells you all sorts of information about your drives. It’s not unknown for the daemon to fail.ĭon’t rely on this! Check regularly on a manual basis! It won’t tell you if anything goes wrong with the monitoring! You cannot assume – even if you put this in your boot-up sequence as you should – that you will be notified about important events. It will daemonize and run in the background, sending an email to the specified address if it detects any problems related to a disk failure. Mdadm –monitor –scan –mail will fire up mdadm to keep an eye on your arrays. The author leaves xosview running permanently on his desktop to provide an overview of system performance. It is currently (2016) being updated to read the status directly from /sys, and should hopefully soon be able to display raid status correctly. It is capable of displaying the state of raid arrays, but unfortunately currently the code is broken – it reads mdstat, and doesn’t understand the current output. Xosview is a venerable utility, and one of the author’s favourites. This will tell you the state of your arrays, and very importantly it will tell you whether any drives have failed, and whether any arrays are degraded. ![]() You should get to know /proc/mdstat, looking at it often.
