I need the MTBF/MTTR calculation/document for R630/R730 with following service tag for my client

SERVER DELL PoweredgeR630 {{Svc tag removed by moderator}}

 SERVER DELL PoweredgeR730 {{Svc tag removed by moderator}}

 SERVER DELL PoweredgeR730 {{Svc tag removed by moderator}}

 SERVER DELL PoweredgeR730 {{Svc tag removed by moderator}}

SERVER DELL PoweredgeR730 {{Svc tag removed by moderator}}




Dell no longer lists specific MTBF's for their servers. This is due to the huge variances in installed hardware, environments, along with just straight usage differences. They stopped being provided around the 11th generation servers.


Sorry I couldn't be more helpful.
