Hi Could anyone explain what exactly "System" is in this graph from SSMC? Attachment:
File comment: SSMC Screenshot allocated capacity 2017-06-23_08-11-03.png [ 13.65 KiB | Viewed 15245 times ] That's almost 15% of the allocated capacity? Thanks Michel |

Usually that's mostly spare capacity and some space is used for system reporter logging and other system data. |

Also keep in mind that's Allocated not Total capacity so it doesn't take into account Free space. It's just showing the percentage of what the system has reserved vs what you have reserved. If you look at the whole picture including free space then system space will be a smaller overall percentage - unless that is you only have a very small system.

I'm worried that it keeps growing... Even on total capacity it's more than 10%... Attachment: 2017-06-23_15-34-05.png [ 26.81 KiB | Viewed 15229 times ] |

Yes, it's spare. System : 4609024 Internal : 234496 Spare : 4374528 Used : 0 Unused : 4374528 So this is the space it needs when a disk fails to do a rebuild, right? https://www.hpe.com/h20195/v2/getpdf.as ... df?ver=1.0 All good then  Thanks (We have 24x 1.92 TB drives)Default: roughly 2.5 percent with minimums Small configurations (e.g. 8000’s with less than 48 disks, 20000’s with less than 80 disks) have a spare space target equal to the size of two of the largest drives of the type being spared. |
