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!

Yellow lights on, new disks to fail... Is that usual on a two years old brand new equipment?

Asked by JoseParrot in Storage Technology, Hard Drives & Storage

Tags: EMC, Clariion CX500, CX500, SAN with 2 x Dell PowerEdge 6850 + 2 x Brocade SW4100

Hello experts,

My company installed CX500 + 2xPE6850 + 2xBrocade + 4CPU Powerpath in 2006.
That time only for a consolidadtion of 5 MS SQL Servers, total of 3 trays with a couple of LUNs, all of them in RAID-5.
Last and during present years, a number of other things are stored there.
Follows a sample list:
- 380 GB SCSI R-5 with Veritas File System under Solaris 8
- 400 GB SCSI R-5 for Oracle RAC under Solaris 11
- 400 GB SCSI R-5 with NTFS for Notes under Windows 2003
- 400 GB SCSI R-5 with NTFS for SQL, used by Veritas Replicator, under Windows 2000
- 200 GB ATA no RAID for Red Hat Linux
- 500 GB ATA R-5 for VMWare
- etc, a very heterogeneous environment

There are servers, accesing such SAN, from single Xeon to 4x Dual Core Xeon to 4x RISC Sun and 2x PA-RISC.

People around is criticizing such macarronade as the worst possible combination to cause bad performance and erroneous behavoir. Of course I'd like to have all my systems running the same O.S. and the same DBMS, one system per tray... but world isn't as we want...

The problem, and I hope the experts can have a hint or a guess, or even an experience by his/her own, is that erroneous functioning seems to ponit in favor of the critic people.
In the last 30 or 40 days, every week yellow (orange?) lights turn on, one disk die, the spare assumes, Dell people change the malfunctioning disk and the cycle repeats again and again.

What are probable causes and how to repair the system?

Jose
