The following example checks the second disk. Just change the number after the comma (,) to indicate which drive in the array you care about.

Install the smartmon tools : apt-get install smartmontoolsĪfter that, you can use smartctl to fetch the status of any particular disk in the array. The first time you want to monitor the smart status of your disks, you must install the smartmontools package. The following is how you can manually fetch the status of a disk in array. Monitoring your disks is important so that you can know to replace any disks that may be failing. Monitoring SMART status of disks in array To install hpssacli, run the commands below:Įcho -e "deb buster/current non-free" > /etc/apt//Ībove cards work well in PROXMOX 2.3, 3.0 and 3.1. HP SmaryArray controllers can be managed using the CLI tool (hpssacli) available from HP. Both controllers are capable of accessing external SAS storage using, for example, HP MSA50 enclosures. The P600 and P800 RAID controllers work well with ProxMox 3.x and 4.x. Works very well.Ĭompaq / HP Smart Array (using in-kernel cciss driver) See Adaptec_Storage_Manager and Adaptec maxView Storage Manager ArecaĪRC-1210, ARC-1212 and ARC-1222 works very well with good speed But be aware, it has no possibility to extend it with an BBU (Battery Backup Unit). Adaptec 5805Z or 6405/6805 with Adaptec Flash Module 600 (AFM-600)Īdaptec 5405/5805 does NOT work with newer UEFI-BIOS Boards!! (This is true for almost all P67,H67,Z68 Boards)Ĭontroller completely working (RAID10), out of the box. If possible, take one with "Zero-Maintenance Cache Protection", e.g. AdaptecĪll Adaptec controllers with BBU unit are known to perform well.

so i usually use konqueror connect - login as admin, default password is 3ware configure Change password, allow remote access, change default port. Note firefox does not display all of the screen correctly. Performance give about 50MB/s on a Raid 5 with 3 HDD's a 1TBģdm2 Management tool debs available from install key wget -O - | apt-key add -Īdd to /etc/apt/sources.list : deb lenny restrictedĪptitude install 3ware-3dm2-binary 3ware-cli-binary Attention: make sure you have write cache enabled and use a BBU! Without write cache the vms seem to 'hang' or 'freeze' sometimes. This Adapter is working well under Proxmox. The site also has repositores for debian/ubuntu based systems ( ) where one can find tools and packages not available directly from vendors, id needed. has info about some vendors raid controllers RAID 10 or 60 is generally considered a good balance of performance to redundancy with RAID 60 providing additional layers of redundancy. If you are looking for performance, look for something that stripes you disks.
That being said, RAID 6 should be considered slow. If you were planning on using RAID 5, consider using RAID 6 instead. RAID 5 should not be used with modern hard drives because rebuild times are long enough that a second drive could fail causing the entire array to be lost. The configuration of the RAID array can also have a major impact on performance. Single SATA WD 400GB: 1360.17 3 x 15K rpm sas RAID5 with write-through: 159.03 (YES, only 159!) same as above but with write-back enabled: 3133.45 Here is a real world example of the performance you can expect. You can use the command pveperf to have a general idea of performance. Some controllers support using an SSD so that a BBU isn't so important, but some SSDs do not deal with power loss well, do your research before relying on this solution.Ī RAID controller using write-through instead of write-back behaves very poorly. That ensures that any pending writes during a blackout can finish being saved as soon as power is restored. If you don't want to loose your data in case of black-out, you need a battery backup (BBU). This way the OS doesn't have to wait until data is physically written to disk, since they are immediately written to the cache and the controller will take care of finishing the subsequent write to the disk(s). Paramount feature for real raid controller if you want high performance is an on board cache and "write back" mode enabled. Embedded controllers are not supported in Proxmox, and if they do work, you are doing so at your own risk. For a RAID controller to be supported, it must be a "real" hardware controller rather than an embedded or "fake" RAID. Look for a line with RAID Controller or similar. You can use the lspci command in the Proxmox command line. This article lists some hardware raid controllers that are known to work well and some information configuring them.
