RHEL4 Update 2 - EVA8000 - Oracle 10g RAC

[Yong Shin Yuh]

Hi Guys,

I am tasked to implement the mentioned(in subject) on 5 64bit RHEL4 DL
Proliant 385 systems. Being new to linux and the storage, I need detailed
advice on how I can do the implmentation for the above. The requirement is
to have 5 load balanced boxes connected to EVA8000 which have a 5TB of
storage space for Oracle data files, sql spool files from scheduled jobs,
archival logs, etc.

I have a few questions to the implementation/solution:

1. How can I load balanced the 5 servers? Can Servicegurad do the job?
How...
2. What LVM and FS type should I use for the LUN created in the EVA8000 for
the 10g Oracle RAC? (I need to store both ORADATA files & normal spool
files)
3. OCFS V2 does really supports normal file types?
4. Any procedures or guideline for such implementation?
5. What are the things to look out for/ needed to be done to configure the
10g RAC on linux Redhat 4 Update 2

Really Appreciate any help or advise urgently.

Best Rgds
Shin Yuh, Yong

That's a 2.6.9 kernel, which means it should be capable of comfortably
supporting an external RAID array. But it's hard for anyone to advise you on
the specific options for that specific RAID storage system. I don't know of
any RAID controllers that will deal with over 2 Terabytes in a single RAID
partition: please let me know if this system does or if you find one that
does. (There's a 32-bit limit on the current generation of controllers, 2^32
* 512 byte blocks yields roughly 2 Terabytes.) How much storage are you
installing? I hope you've left spare space for hotswap drives, RAID5 parity
drives, and occasional expansion needs.

Other factors, such as how much data overall you need to see as one file
system, will determine whether you need to use software RAID on top of that.
If the 5 TB needs to be one file system, you'll need that. I've had good
success with Linux's built-in software RAID and ext3, and had serious
failures with reiserfs when forced to run an fsck after hardware problems
corrupted the file system. I'd say ext3 is more reliable now. Also, consider
using LVM or Logical Volume Management if you need to dynamically
repartition or take snapshots of a Linux file system.

Where are you? I may know someone competent to suggest, in the Boston area
or in Germany.

Just tried to answer your question in aol.

Multi-posting is antisocial.

If you are going to ask the same question in more than one
newsgroup, crosspost. You conserve resources on NNTP servers, and
other readers see the follow up answers and do not have to
provide the same answer.

It makes it much harder to keep track of a discussion. Also, once
a reader has "read" a message in one group, they do not have to
see it again unless someone has provided a follow up.

To crosspost, just add a comma and the other newsgroup(s). If
you do cross post, do not get carried away. Pick suitable groups.

Example: for a scanner
linux.redhat.install,comp.periphs.scanner,alt.comp.periphs.scanners

See http://www.cs.tut.fi/~jkorpela/usenet/xpost.html for more
info.

Good luck
