Does it offer performance advantages over NFS root?
- a96 5mo agoI kind of expect the performance is worse, but one neat thing is that iscsi is a block device, so you could run e.g. disk crypto, volume management or whatever on it. Not to mention any FS. And you don't need to deal with NFS or RPC.
- bobmcnamara 5mo agoDunno about performance vs NFS, but I've stuffed an unaware OS onto ZVOL-over-iSCSI using a NIC with option ROM.
- burner420042 5mo agoThey operate at different layers. iscsi is a block device: you gain a 'disk drive' sitting on your network. A dedicated network for disk traffic and use it to host on-prem virtualization. It's called a SAN array.
- Tepix 5mo agoSure, but eventually you will reach a layer with files, usually. Then you can run benchmarks and compare numbers.
