Yes, at least for the storage stuff, LVM2 can do much of this. |
9 |
But my ideas go some steps futher, eg: |
10 |
|
11 |
* mapping blocks instead of larger chunks |
12 |
* defect management directly on block basis (w/o additional |
13 |
stacking layers). |
14 |
* distributed storages (not just disks, but several hosts) |
15 |
* volumes attributes which let the volume manager decide how/where |
16 |
to actually store blocks, eg.: |
17 |
|
18 |
+ mirroring: min/max number of copies, allowed device classes |
19 |
+ compression: allowed algos or grades |
20 |
+ encryption: ciphers, keys, ... |
21 |
+ reliability: hard/limit (eg. use "unstable" disks exceptionally) |
22 |
+ caching: allow some volumes to be cached on fast devices |
23 |
... |
