poweredge 1850 setup tips

[Gary Sewell]

Thanks Tom,

 

We’re going to go with 64 bit Debian, we currently have 8gb in a 32 bit
Debian installation but the hassle in setting it up was a nightmare due to
the need for additions to the original kernel.

 

I’ve purchased 2 x PERC4e/DC (I’ve been told the motherboards are
PCI-Express hence the “4e” and I could only find 4e available in Dual
channel hence the “DC”) raid cards to go into the MYSQL servers to run RAID0
for speed. Redundancy should be ok with hot swaps and replication to the
slave. The other 3 we will just run off the built in scsi controllers as
they will only be running apache.

 

Thanks for the tips.

 

Gary.

Dear Gary Sewell, 

I have 16 of those computers. 

I have run 32 bit and 64 bit Linux on them, and they run slightly better at
32 bit os (I use RedHat enterprise 4) .  I do run six of them at 64 bit OS
for large memory jobs. 

Mine came with a perc controller card, and I switched the  73 Gb drives from
raid 1 to raid 0 for speed, and I got about a 5% improvement in speed. 
  
Of course to talk avantage of the 8 gb memory, 64 bit os is better.

poweredge 1850 setup tips

 


 

 




Hi to everyone, 
  
We’ve just purchased 5 x used poweredge 1850 
Each has 
2 x 3.4Ghx Xeon 
8G RAM 
2 x 73G SCSI 15k drives 
  
2 will be running Debian and MySQL 5.0 (80% reads) 
3 will be running Debian and Apache 1.3/modperl 
  
We would appreciate any input into 
  
32 / 64 bit OS choice? 
  
and 
  
RAID Disc controller? They have not shipped with a raid controller so can we
go with an onboard solution if there is any or can a PERC card solution be
recommended for optimal speed. 
  
And 
  
RAID configuration? Toying between RAID0 or RAID1. 
  
Thanks All. 
Martin.
