However, being able to push something like this out to business and corporate clients may well be a viable opportunity.
Microsoft already makes it. http://blog.tmcnet.com/blog/tom-keating/microsoft/office-communications-server-2007-public-beta-launches.asp
The phonebook syncs to Exchange/Office Communicator, and you log in via active directory on the phone.
It's not about transportation, it's about destination.
So, how about your safety deposit box at the bank?
They can't just search that...
Uhhhh...dude? Did you not bother reading the multiple times the guy said he was on a secure INTRANET and therefor you could yum all damned day long and it ain't gonna do squat because there is NO Internet on the secure side?
Uhhh...dude. I run yum on my intranet. My yum repository is on my intranet.....The machines arn't pulling updates straight off the internet. Do you even understand what's going on here?
So you could put thirty three hard drives in RAID 0 and have the same number of IOPS, and your latency would still be worse.
Actually, thats incorrects, Here's why:
When you calculate IOPS, a good portion small of reads and writes get executed at random places on the disks. When you you make one filesystem write on a raid0 set (depending on how smart the raid0 controller is), it will be locking up several or ALL the disk spindles for that individual read/write.
The IOPS are negligibly better on a 33 disk raid0 set, and depending on your disk controller, it might be worse (every write equates to 33 dma requests).
It is faster for reading large files though, but that is NOT what a fair IOPS test measures.
For read operations, you can double your read IOPS by using a mirror. This is because ony semi decent controller will split all the read requests between the drives in the mirror. When your issuing lots of read requests from several threads, the load should be approximately equal across the drives.
