The Solution Rating System
|
|
| With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating. - The Grade of the Solution
- The Zone Rank of the Expert Providing the Solution
- The Number of Author and Expert Comments
- The Number of Experts Contributing
- The Feedback of the Community
Your Input Matters Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site. If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support. Thank you! |

Asked by cps999 in Storage Technology, Hard Drives & Storage, VMware
Hi,
we just recently added a FC network to our existing 1Gbit NFS on a FAS2050 in active/active mode. We are running three hosts (DL380 G6, dual QC, 72GB RAM, 0 HDD) with ESX4i and two Qlogic 4 Gbit HBA on each host, everything's connected via two Brocade 300 switches.
I'm a bit dissapointed with the preformance of FCP, I moved a VM with two vmdk's from NFS to FC to run performance tests, copying a file from one vmdk to the other returns an average of 60MB/s, compared to about 30 MB/s on NFS. Eventhough this is double the speed of NFS, i was kind of expecting an increase to at least 200MB/s (this is what the Netapp SE said we could expect). Could someone possibly direct me to a comprehensive installation and configuration guide for FCP and ESXi4, or give a hint how to get FCP up and running? We've configured everything according to the documentation that comes with ESXi4 but something big seems to missing.
The Brocade performance monitors show practically no bandwith utilization.
