I have recently started looking at server resilience and availability in |
| 2 |
the context of a hardware failure or hardware upgrade. I've come to the |
| 3 |
conclusion that it would be very desirable if terrabyte-scale data did |
| 4 |
not need to be restored from backup. This isn't a commercial server - |
| 5 |
so I'm interested in minimum cost approaches. |

With this in mind, I'm interested to discover what represents |
| 8 |
state-of-the-art from the perspective of the OS and its configuration. |
| 9 |
Issues I envisage are: |
| 10 |
|
| 11 |
* With NAS, it would be desirable to have a Linux filesystem rather than |
| 12 |
access files over CIFS - this raises further questions about protocol... |
| 13 |
is NFS as hopelessly outdated as it seems? Are there any products that |
| 14 |
offer NFS access? Are any of them secure? |
| 15 |
* With a SAN, questions of filesystem features are diminished - but |
| 16 |
questions of access protocol remain. What is best supported by gentoo? |
| 17 |
* Do any gentooists have any inexpensive hardware configurations that |
| 18 |
work especially well? |

Any hints or tips? |
