Fraud prevention. It's a way of making sure the product is actually 1) for the project (grant) that paid for it and 2) going to the place they were told it was going.

It's one of the many rules that was set to stop someone from doing something they were doing but weren't supposed to be doing.

I am Tegile's VP of marketing. We love SFD events, and we are at several of them throughout the year. Sometimes, SFD events conflict with other shows we are at, or as Matt said, sometimes they fill up fast. Glad to hear that you value them - maybe I'll see you at the next one!

I've been in various combinations of graphics, development, and IT for twenty+ years, and have even been a commercial AV installer who carried a punchdown tool every day. But I never once had occasion to use it, as the grunts always terminated the keystones in the rooms I built.

Yet now it falls to me to shuffle extensions in an aging PBX system and I'm staring at the wall-mounted pasta muttering "Umm..."

I appreciate the support. Thanks for the comment!

You owe me $20.

LoL!

Seriously, congratulations and good luck!

RAID 5 is perfectly fine when kept in small disk sets, typically no larger then five. Also the failure rates are no where near what's being touted, people are off by two orders of magnitude or more. The BER published by manufacturers are worst case scenario with the disk working a harsh desert or freezing environment not a relatively clean data center. That number is also calculated prior to the QA process at the manufacturer removing failed

Now for what is really going to shock everyone and prevent you from sleeping. No amount or combination of RAID protects you from data loss, period end of story. This is because the primary reason for failure is not wear & tear but faulty manufacturing. Drives are either good or bad with the manufacturer trying to catch the bad ones before shipping. Bad drives then to happen in batch's, you don't get one bad drive but dozens if not hundreds out of a batch. When we order storage we tend to order large drives from a single manufacturer which then sends us disks from what's on hand, typically all with the same manufacture date, often from the same batch. Thus if one drive in a RAID is going to fail then there is a high chance that several others from the same batch will also fail. That RAID10 has no greater reliability advantage then the RAID5 but at a significantly higher cost.

Performance is based on the number of reading disks and the quality of the FS involved. A four disk RAID10 set will have the same read performance as a five disk RAID5 set while having half the write performance and half the capacity. Also if we're talking a SAN environment then the storage processor does it's own form of error checking and integrity validation.

In all cases the true source of corruption are file systems that are not self-repairing. It's just plain crazy to store data on a file system that doesn't do it's own integrity checking. I recommend using a ZFS or similar file system for any serious data storage. ZFS itself maintains layers upon layers of CRC's and is constantly doing integrity validation and using a copy on write methodology.

Finally no amount of RAID or storage subsystem is a replacement of data replication / backup.

You *can*, in-fact, use DOMAIN\Username conventions with xfreerdp, you just need to escape the backslash e.g. -u:DOMAIN\\username I do qualify this with a "Works for me! (™)" but I thought you might want to know.

Yes, absolutely. The talks will be hosted at both Vimeo and YouTube, and embedded in the pages linked to at http://www.techfieldday.com/sfd3/
