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!

Migrating RAID arrays between Dell PowerEdge servers

Asked by NacMacFeegle in Miscellaneous Hardware, Personal Computers

Tags: raid, dell, poweredge

We're planning some DR scenarios and one of the things I need to understand is the limits / options for recovering data from RAID 1 arrays where the original server has died. The original server is set up with 2 RAID 1 arrays O/S and data. What I want to do is take the Data array (either as a set or one of the 2 mirrored disks) and see / access the data on the disk from another server.
I need to understand if this is possible on the following servers

 Dell 2500 (Perc3/Di) to Dell 2500
 Dell 2500 to Dell 2600
 Dell 2500 to Dell 2850
 Dell 2600 (Perc4/Di) to Dell 2600
 Dell 2600 to Dell 2850
 Dell 2850 (Perc4/Di) to Dell 2850

From reading around the forums it appears that this is only possible on the Dell 2500 boxes if the new server (recipient) has the same model and firmware of array controller as the old server (donor) due to LUN roaming not being insttalled on the 3/Di card, however I'm really hoping that someone out there can tell me otherwise.

This could cause me a lot of work and pain if I get it wrong so 500 points up for grabs

Any ideas?
