| mcape | hi all – quick question about compute sizing for Swift | 04:51 |
| mcape | we have ~350TB of data (~350 million small files), 3x replicated across ~150 disks (8–10TB each) | 04:51 |
| mcape | currently each replica lives on a PACO server: 20-core Xeon E5-2630 v4 @ 2.20GHz with 32GB RAM | 04:51 |
| mcape | cluster is ~85% full, and storage load is moderate: ~50MB/s upload and 120–150MB/s download during peaks | 04:51 |
| mcape | usually we see ~60–70% CPU util, which seems ok | 04:52 |
| mcape | but recently we did a few 8TB disk replacements, and we hit high iowait and brief instability – compute can't keep up | 04:52 |
| mcape | so I’m wondering: are there any rules-of-thumb for how much CPU or RAM per TB of storage? | 04:52 |
| mcape | mainly interested in making recovery/rebalance stable even when a disk fails | 04:52 |
| mcape | any insights or examples from similar setups appreciated! | 04:52 |
