Document URL: https://docs.google.com/viewer?url=https%3A%2F%2Faccess.redhat.com%2Fsite%2Fdocumentation%2Fen-US%2FRed_Hat_Enterprise_Linux%2F6%2Fpdf%2FPerformance_Tuning_Guide%2FRed_Hat_Enterprise_Linux-6-Performance_Tuning_Guide-en-US.pdf

Section Number and Name: 

Describe the issue: 
"RDMA over Ethernet (RoCCE) implements..."

Suggestions for improvement: 
Should  be "RDMA over Converged Ethernet (RoCE)"

Additional information: 

There are a bunch of other minor updates needed, such as:

Section 1.3.3, Page 19
"...infrastructure via a single converged network card (CNA). Standard..."

Should be:  converged network adapter (CNA)

Section 2.1. 64-bit Support
"...support up to 8TB of physical memory."

Link below shows 64TB maximum.

Not sure where the best place to suggest the others are. It's an *excellent* guide overall, but there's some information that needs to be updated.

Thanks for this; I'll see if I can get these in for RHEL 6.5.
Comment 3 Laura Bailey 2013-10-14 21:42:45 EDT
Looks like we can fit this in, as translation hasn't started yet. Adding flags.

A few others:

“Enterprise Linux 5. Ext4 is now the default file system for Red Hat Enterprise Linux 6, and is supported for a maximum file system size of 16 TB and a single file maximum size of 16TB.”

These values appear to be incorrect. The maximum filesystem size for EXT4 I believe is in the exabyte range.

I can submit a new report for these individual items, but there are quite a few similar ones throughout the guide.
Comment 9 Laura Bailey 2013-11-26 19:18:24 EST
Closing these bugs as CURRENTRELEASE, as all are now available in Red Hat Enterprise Linux 6.5 GA.
Comment 10 Laura Bailey 2013-11-26 19:23:22 EST
Closing CURRENTRELEASE since this is now available in RHEL 6.5 GA.
