Open-E: Configuring A RAID Array
After selecting the disks that you want to be part of the RAID array , Open-E sets up the software-based configuration on Thecus' N8800PRO. We chose to use all eight disks in a RAID 6 arrangement. Initializing the 16 TB array took about 12 hours, which is neither impressively fast or frustratingly slow for an array of this size.
Once the array is in place, the system displays a summary screen of all RAID-oriented parameters.
As an aside, if you want to optimize the array for throughput or I/O performance, you can modify its block size between 4 and 256 KB. In addition, you can choose the algorithm to use for RAID 5 and 6, affecting the array's performance.
For the hardware price, I'd go for a Dell R510. it's about the same price. Then I'd run CentOS 5 or 6 on it. CentOS can do most of what this thing can do with no cost. Or the business could opt for Win 2k8 r2 for $600 more or MS SBS for $800 more and get an easier to manage system that any yahoo proclaiming to be an admin could fix.
IOP performance is garbage on SATA drives, and I've seen FreeNAS do a better job than what was portrayed in this article.
As far as the performance, I'd say it was right in line with low end devices using iSCSI.
Any iSCSI devices you can pretty much count the 1GB ethernet link as the bottle neck, which puts it around 100 - 125 max. 2x Multi pathing may bring that up to around 190, but good luck achieving usable transfer rates of 250+ as peter claims.
For the money i'd choose dgingeri's dell in a heart beat.
Al changes , done to the storage , were done in some xml files of the application
Needles to say that whenever you did anything in command line , the web apllication would not recognize the result
That said, keep up the good work in your core space Tom's!
