Storage

[Igaduma]

Hi all,

I'm looking to expand a E-250 with an external storage array.
Currently it's maxed out on it's internal scsi drives.
So, an external with a new scsi card would fit the bill nicely.

The Storedge D2 array seems to be the intresting one.

Does anybody have experience with this storage array ?

the E-250 is running 2 oracle databases, not more then 2 Gb /database.

Thanks for any info!

Hello,

What kind of data protection do you plan to use: mirror, raid 5, ....? I ask this because with the D2 youll have to raid with software, and for example a raid5 will cause a system performance degradation, specially if a disk crashes.

I think that is not a volume question, just a performance question (specially with some Oracle databases, but it depends on your database design, your speed needs, etc...)

If you can afford it, I would select the new 3310, with the hardware raid controller (take a look at the prices for both products and compare them, but maybe they are similar).

Bye,

Raid 0+1 is recommended for RDBMS performance. Anything else will slow the database queries. Also, try spreading data and indexes on different spindles Too bad I.T. is not cash business
