Talk:N+1 redundancy

Expansion/Merge Discussion
There is little information on other types of redundancy, aside from 1+1. There is also little information about application. This article alone I don't know should be a full article as it has such little information. If it is expanded to an entire new article, it should probably be included under Redundancy. The only thing is, some of it is covered under High-availability cluster, but not all, so it would require some expansion there if it were merged. If I could get a second opinion, that would be great. --Dpaulat (talk) 18:40, 27 June 2008 (UTC)

I agree that this article needs to be merged into Redundancy (engineering) this is actually quite orphaned from where it should be, So lets see what others think! Read-write-services (talk) 22:17, 20 December 2017 (UTC)

I found this article useful for the specific definition of the "N+1" type. Redundancy is a nebulous topic, with "Fail-Safe", "Fault-Tolerant", and "Backup" all having nuanced meanings. Redundancy (engineering) relies heavily on empirical examples and seems inadequate for such a broad topic. --sry no account — Preceding unsigned comment added by 192.31.106.35 (talk) 15:49, 15 May 2018 (UTC)

I don't think this should be merged. It should be expanded if anything. The term N+1 is increasingly used in datacenter and cloud technologies which are seeing massive growth. It is not a term often used in other forms of engineering. SplatMan DK (talk) 12:51, 13 August 2020 (UTC)

N−1 redundancy in the electricity sector
I have always heard this concept being described as N−1 redundancy in the electricity sector. If there is a suitable source, this remark could be added to the main article. RobbieIanMorrison (talk) 11:18, 10 February 2023 (UTC)


 * Yes, I came here checking if someone else made a typo and meant N-1. Imagine my surprise. I've always encountered the measure as N-x, where N is the total number of elements, and x is how many (random) elements can fail without taking the system down with them. The German wiki has this article:, there's this paper by the Serbian state power company: (see p.8, 1.2-16) , and I can probably dig up a university text book that mentions it. Can't guarantee it being in English, though. Aqarius90 (talk) 22:27, 11 January 2024 (UTC)
