# Personal NAS
|
|
|
|
## Brief
|
|
|
|
Scoping an 76 terabyte onsite Network Attached Storage (NAS) and Networking solution for personal usage
|
|
|
|
- by `rskntroot` on `2025-02-15`
|
|
|
|
## Assumptions
|
|
|
|
To acheive redundant 76TB, RAID 6 will be used.
|
|
This requires a total of 6x 20TB drives.
|
|
The max supported size would be 96TB using 6x24TB drives.
|
|
|
|
At a minimum, the storage solution must provide redundant copies of the data.
|
|
The solution must function in the event of a single-drive failure.
|
|
Individual storage drives used must be enterprise-grade, warrantied, with the expectation of 1 million hours MTBF.
|
|
|
|
Given standard network connectivity is at or under 1Gbps speeds, 10Gb/s internal networking is not expected.
|
|
2.5Gb networking can be achieved between a NAS a client with a 2.5G switch.
|
|
However, the storage solution should provide future expansion options for 10Gb/s networking.
|
|
|
|
Concerns regarding redudant power or battery backup for the solution are outside the scope of this document and would be handled by the customer.
|
|
Recommened best practice for storage solutions is to keep on a battery backup to allow for graceful shutdown.
