| 03:19.56 | ChoHag | Yeah JBOD is a specific thing (which I've never really seen the point in - all the disadvantages of RAID with none of the advantages) |
| 03:20.32 | ChoHag | More like an AID, except unhelpful. |
| 06:30.35 | morsing | Any Perl people awake? |
| 08:24.20 | ChoHag | " I wonder if we should stop calling them browsers and start calling them webVMs. " |
| 08:43.40 | wethrin | ChoHag: I guess it's just an extra layer of indirection. So you set up your software raid on JBOD, rather than individual disks.... |
| 08:43.43 | wethrin | Which seems silly |

| 12:33.49 | vagarwal | i am not sure if I can expose the disks directly to the OS. They have to go through the raid controller. |
| 12:34.33 | yaMatt | the raid controller should let you do that |
| 12:34.47 | vagarwal | a work around i found is to create 6 individual virtual disks with one disk each |
| 12:35.19 | vagarwal | we bought 8x dell r730 for hadoop installations |
| 12:35.28 | vagarwal | that is what dell _advised_ |
| 12:36.05 | yaMatt | we have 10x HP DL380 Gen 9s, they just presented individual volumes |
| 12:36.20 | vagarwal | due to lack of time, we couldn't replace the raid controller and moved forward with 1 physical disk per virtual disk |
| 12:37.30 | yaMatt | HDFS works on physical disks anyway, you just need a plain file system on the disk and mounted and then tell it where to look |
| 12:38.25 | yaMatt | it works a bit like Ceph in that it just places file objects on disks and manages the resilience for you |
