Does it make sense to have a metalun made of LUNs on two RAID groups, where 1 RG contains 5 disks and the other 9?
Can the CX 700 use this config efficiently? Both RAID5.
I guess not, but I am not sure.

I'm afraid I don't know much about SAN's so please forgive my lack of detail or technical terms.
As a developer I've just completed and put on an existing production system a new application but it would appear to have tipped the scales regarding the performance of the backups being taken from the…

Hello,
I currently have 2 cPanel web servers that are little 1RU dual cpu quad core xeons. They have a lot of resources for processing and handling web requests, and never exceed more than 10% cpu usage. They also have plenty of RAM.
The problem is though that they both have RAID 1 160Gb SAS hard…

We have a poor man's SAN setup in a 1U Ubuntu server running iSCSI-Target with two 300GB drives in RAID-0. We then are using it for block level storage for virtual machines. The hypervisor is connected to the SAN via gigabit on a dedicated VLAN and interfaces.
We only have a single virtual machine…

Hi
We have a database server running oracle rac. We were recently running out of space on the main LUN that it is attached to. I created a new 100GB LUN and concatenated this onto the existing LUN creating a new MetaLUN. After some messing I managed to get linux to recognise the new space. I then…

Imagine you sell those metallic digits used to number houses, locker doors, hotel rooms, etc. You need to find how many of each digit to ship when your customer needs to number doors/houses:
1 to 100
51 to 300
1 to 2,000 with zeros to the left
The obvious solution is to do a loop from the first…

I've found the symbol :=: in some Clarion code and I can't seem to figure out exactly what it does. The code was written by a previous developer many years ago, so I can't ask him. I also have not been able to find any results for "colon equals colon" in Google.
Here is an example of the code,…
