Hi,

 

The backplane has no speed, just communication ports between drives and RAID controller. If the server is running on software RAID, then it only support 6Gb/s.

Dear @DELL-Joey C 

are you sure?? , because I am pretty sure the connector for 12GB/s has more contacts , ( more cables ) are needed to achieve 12GB/s vs 6GB/s ... is not the same as just swap the HBA , RAID .. 

anyway I will try it though to get a 12GB/s Raid card and a proper cable from :
sff-8613 to sff-8087

thanks

Hi,

 

I did a search for available backplanes for R620, only 1 type of backplane returned result. Though, I too had the same thoughts about the cables so I did ask the senior technical. 

 

What RAID controller are you planning to use?

Re: R^20 or R720 Backplane upgrade to 12GB/s SAS support

Dear @DELL-Joey C 

I haven't done my research yet although H330P is a potential candidate maybe 


although I haven't made my proper research , 

also I need to look the lanes of CPU and Mobo lanes and what they can even handle it , lastly get proper cables , and also get the amount to buy a 12GB/s sas drive ( they cost an arm and a leg ... ) 
plus I have no idea if it will even manage to perform at 12GB/s if there are other bottlenecks like backplane muplexer , cables , CPU lanes and Speed , caching of the RAID card or the OS , etc etc etc etc 

In general is a very very deep rabbit hole I decided to go down in ..

 

Now in general since China trading is out of the question this would take about a year to be done ( where this conversation will be obsolete since R630 the support 12GB/s sas natively without going Frankenstein on it ... 

 

If you get any input from the senior tech please keep me posted , 

 

Thank you in advance

Re: R^20 or R720 Backplane upgrade to 12GB/s SAS support

Hi,

 

I think that's the reason that I only found 1 type of backplane, which the connector is similar to 6Gb; cause the server is unable to support series 9 RAID controllers. Series 8 RAID controller only supports 6Gb only. 

 

RAID controller series: https://dell.to/3cQfYa4

 

RAID controller supports: https://dell.to/2XjsKro
