Will it cause any performance impact or any other issues if there are no DAEs on BUS 0 on a VNX5600? All the DAEs - 17 total - are balanced across BUSES 1,2,3,4,5. I know it would be best to load balance them across all the available buses, but it is already cabled and initialized omitting bus 0. So bus 0 can be used for the future expansion. Maybe it is worth re-cabling the array and utilizing all the buses?
Appreciate your input.
My opinion is that you should recable it with alternating buses. For example, the first few DAE's would be 0_0, 1_0, 2_0, 3_0, etc....
This allows for all buses to be used early on in the expansion.
Does it have any lag?
As per EMC that config would not be correct confid Ad-astra.
Will it work? Yes practicality it should
Will that create a problem? High chances of yes
And if there is a performance issue then the first recommendation would be to re-configure.
Maybe it is worth re-cabling the array and utilizing all the buses?>> Oh yes
It will cause in imbalance. Depends on how hard you push the array and the other available buses. Also, if you dont have 0_0 cables, im not sure if it will work. I believe vault has to be in and cables to 0_0
Thanks Sheron, please see my comments on bold.
Does it have any lag? - Unknown, there is no production data on it yet.
As per EMC that config would not be correct confid Ad-astra. - This is funny, because EMC field services engineers cabled it this way, omitting bus 0. I guess, if it goes against EMC best practices, they should have brought this up, not me, after it is cabled and initialized.
Will it work? Yes practicality it should - It does work, at least it is up and running, no prod data on it yet.
Will that create a problem? High chances of yes - Why will it create a problem? Could you elaborate on this.
And if there is a performance issue then the first recommendation would be to re-configure. - I agree, but it will depend on the nature of the problem.
Maybe it is worth re-cabling the array and utilizing all the buses?>> Oh yes - I agree, just wanted to find out what complications may come out of it.
Here is what could help us
From page 128 to be precise.
Honestly I can think of many issues but cant find any docs to prove my point. Gimme a lil more time to think to figure what could be the issue.
As per what I understand I would think think that the BUS 0 is kept only for the DPE.
So BUS 0 is free at the moment if we need to add any enclosure to it.I should be able to use the BUS 0 for future use.
Error: ?? , i was thinking about any parity mismatches due to the way the array is connected.
However how practical is the error to show up is something I honestly dont know.
Can you check with the support team and see what they think of it.
If you get a green flag from them then , yaaaaay, we are good.
If they say no can you let us know why, as it would help me clear my doubt.
Thank you Ad_astra, you made me think a bit today
