Kayte appreciation thread

What a strange way to start a new week.

After a virus took down one of my computers last Friday I had to spend 3 days getting the O.S. back up with all of the latest software drivers working for Windows 7 64 bit then This morning one of the internal harddrives died on me.

I have hardware RAID on the machine so I could do a cold reboot to it, normaly only servers use RAID but for redundency this Geek set up hardware RAID level 1.

The harddrive that died is 9 months old and made in China, Thanks Western Digital for outsourcing.

Reliability

If you ask an IT professional to list the reasons why he or she set up a RAID array, one of the answers likely to be mentioned is "increased reliability". They probably don't really mean it though. "reliability" is a vague word when it comes to redundant disk arrays. The answer of increased reliability is both true and not true at the same time.

The reliability of an individual component refers to how likely the component is to remain working with a failure being encountered, typically measured over some period of time. The reliability of a component is a combination of factors: general factors related to the design and manufacture of the particular make and model, and specific factors relevant to the way that particular component was built, shipped, installed and maintained.

The reliability of a system is a function of the reliability of its components. The more components you put into a system, the worse the reliability is of the system as a whole. That's the reason why compex machines typically break down more frequently than simple ones. While oversimplified, the number used most often to express the reliability of many components, including hard disks, is mean time between failures (MTBF). If the MTBF values of the components in a system are designated as MTBF1, MTBF2, and so on up MTBFN, the reliability of the system can be calculated as follows:

System MTBF = 1 / ( 1/MTBF1 + 1/MTBF2 + ... + 1/MTBFN )

If the MTBF values of all the components are equal (i.e., MTBF1 = MTBF2 = ... = MTBFN) then the formula simplifies to:

System MTBF = Component MTBF / N

The implications of this are clear. If you create a RAID array with four drives, each of which has an MTBF figure of 500,000 hours, the MTBF of the array is only 125,000 hours! In fact, it's usually worse than that, because if you are using hardware RAID, you must also include the MTBF of the controller, which without the RAID functionality, wouldn't be needed. For sake of illustration, let's say the MTBF of the controller card is 300,000 hours. The MTBF of the storage subsystem then would be:

System MTBF = 1 / ( 1/MTBF1 + 1/MTBF2 + ... + 1/MTBFN )
= 1 / ( 1/500000 + 1/500000 + 1/500000 + 1/500000 + 1/300000)
= 88,235

So in creating our array, our "reliability" has actually decreased 82%. Is that right? Why then do people bother with RAID at all? Well, that's the other side of the reliability coin. While the reliability of the array hardware goes down, when you include redundancy information through mirroring or parity, you provide fault tolerance, the ability to withstand and recover from a failure. This allows the decreased reliability of the array to allow failures to occur without the array or its data being disrupted, and that's how RAID provides data protection. Fault tolerance is discussed here. The reason that most people say RAID improves reliability is that when they are using the term "reliability" they are including in that the fault tolerance of RAID; they are not really talking about the reliability of the hardware.

What happens if you don't include redundancy? Well, then you have a ticking time-bomb: and that's exactly what striping without parity, RAID 0, is. A striped array without redundancy has substantially lower reliability than a single drive and no fault tolerance. That's why I do not recommend its use unless its performance is absolutely required, and it is supplemented with very thorough backup procedures.

A Techies work is never done.

Good morning {{{{{{Shagly}}}}} :kiss::heart:

WOW! My brain hasn't been around that stuff for years. Like back to when I was working in product design, along with quality assurance, manufacturabilty, all that "stuff."

Your post almost makes my head hurt. ;) :kiss:

Glad you are back with us. Hope you are able to catch up with your online classes without too much trouble now that you are back online. :)
 
Stopping in to say Good Morning & leave hugs-squeezes & :kiss:sss for Kayte & whoever else need some :)

{{{{{{PJ}}}}} :kiss::heart:

Thank you sexy. Mmmm so that is what I felt this morning. :devil: Leaving :kiss:es and hugs and a gentle grope too.

Have a terrific Tuesday. :D

The computer is only running on 1 harddrive presently, I set up a mail warranty exchange with Western Digital, the stuff from China has no quality control.

Glad to hear there is an exchange program you can take advantage of. :D
 
Morning Kayte,

I hope you have something fun planned for the weekend.

I'm in basketball hell here, so I plan to finish off my book and perhaps do some deep cleaning of this house.

If you have nothing else shakin...come on by :)

Geee you should have taken a trip down here where it's ALL live...
Tampa has the NCAAs going on over at the Forum but....
we have the beach & the Grand Prix over here in St. Pete!

TGIF {{{{{{kendra}}}}} :kiss::heart:

How nice to see you. It is always such a delight. :)

Basketball hell. :( Sorry to hear that. My teams are still ok. Looking forward to Marquette winning tonight. The UW Badgers did last night. :D Yes two WI teams. My college ~ Marquette and my Dad's and neice and nephew's ~ UW Madison.

Enjoy your book. Now as to deep cleaning I do have some of that I also need to get to. Sighs it is spring....

I do need to stop by some of the other places here. I have been remiss or MIA. :eek:

Have a fantastic Friday and a wonderful weekend. :kiss:

{{{{{{{Starry}}}}}} :kiss::heart:

TGIF sweetie. :D Wow! There are many things happening in your area. And there's all of the spring break people there too. :eek:

Take care of yourself hon. Thinking about you. All of the things you are doing and dealing with. :kiss:
 
Stopping in & leaving early Morning hugs-squeezes-:kiss:sss for {{{Kayte}}}}:rose: have a great Day & a fun Week :rose:
 
I would usualy suggest we should play in the rose garden yet it is too cold for that. :rose::heart:

Good afternoon {{{{{Shagly}}}}} :kiss::heart:

Yes it is still to cold and damp here for that as well. And in addition I don't have a rose garden. ;)

I had quite a day yesterday. Headed down to see an old friend. We hadn't seen each other in years. We had a great time.

The weather was atrocious. Terrible pounding rain most of the day. The drive wasn't only nasty because of that but because of the amount of construction on the freeway! :eek: No matter which way I took, through the city or around it things are torn up, lane shifts. :eek::eek: And it was raining and windy. Glad I got home too.

Still it was much better than it being snow. That would have been at least a foot of the stuff. :rolleyes:

Hope you are having a marvelous day.
 
Stopping in & leaving early Morning hugs-squeezes-:kiss:sss for {{{Kayte}}}}:rose: have a great Day & a fun Week :rose:

Thank you {{{{{PJ}}}} :kiss::heart:

You are such a sweet and sexy guy. Thanks for all of the goodies and sending lots of the same back your way. Have a fabulous day and a fantastic week.
 
Another gray overcast day in N.Y. is here, 36 Deg. F. and it is not snowing....so far.

I am repoting the hanging Spider plant at the same time I am fending off these cats, for some reason they think it is a salad. :cattail:

Either a salad or a toy. :D It is 34 degrees here and pouring rain again. There may be some flooding as we got 1.5 inches of rain on Sunday. Oh well, as long as the temps stay above freezing I'm happy. :)
 
new toy for Kayte...

ok now I have found flying cars... our news is nothing if not varied.

Flying cars coming to Sun n' Fun in Lakeland?

Among all the talk about the vintage war planes and aerobatic aircraft featured at the Sun n' Fun Air Expo in Lakeland next week will be conversation about some even more exotic vehicles.

Flying cars.

Aviation engineers are molding together airplanes that can roll down the road and cars that can soar into the atmosphere.

The next generation of flying machines is coming off the production lines next year at one company in Massachusetts, engineers with Terrafugia say. The model is being marketed to pilots by Terrafugia, which is Greek for "Escape the Earth."

The company already has taken 100 orders for the two-person car plane called the Transition, said company spokesman Richard Gersh.

"We are really in this market space by ourselves," he said. "There are other, similar designs. There's a flying motorcycle that's built from a kit and a flying dune buggy."

He said ideas to widen the flight market are flying around the nation now.

"In the aviation community, we are aware of them and we do compare notes," he said. "There are a lot of ideas out there and we appreciate all of them. If nothing more, it adds to the excitement of aviation and that's good."

Gersh and three other company representatives will be at the Sun n' Fun to answer questions and give updates. The prototype, however, will remain in Woburn, Mass., though a 4-foot scale model of the next generation of flying car will be on display at the air show, Gersh said.

The Sun n' Fun Air Expo takes over the Lakeland Linder airport for the week, transforming the small facility into the busiest airport in the nation with some 40,000 takeoffs and landings over six days.

Grounded spectators also clog the grounds, with more than 150,000 visitors expected to pay the $150 for the week or $35 each day to get into the event.

Acrobatic planes, vintage war planes and experimental aircraft that offer glimpses of future air travel will be on display as well. The U.S. Navy's Blue Angels are scheduled to put on shows from Thursday through Sunday. It's the 100th anniversary of Navy flying.

The event begins Tuesday and lasts until Sunday, April 3.

Terrafugia started five years ago, two years after the Federal Aviation Administration created a new category of plane – light-sport aircraft – that opened up the market for new car-plane prototypes.

The company began drawing up plans for a flying car that would fit into the light-sport aircraft category. The target audience: pilots, first off, then flight enthusiasts and businesspeople taking trips of less than 300 miles.

One drawback could be the price tag for such a contraption: $190,000.

The company says fuel costs and hangar fees would be cheaper as the flying car could fit into a regular garage and runs on premium gasoline.

Of course, the prototypes all need regulatory clearance from several federal agencies, and one minor hitch could derail the whole endeavor.

Not as far along in the production of a flying car is Dezso Molnar, an engineer-entrepreneur from California whose prototype is in the design stage. He plans to attend the Sun n' Fun and display his model, as well.

In October, Molnar received a U.S. patent for a flying motorcycle, though he's not making any full-ahead plans for mass production. He has one in storage, which he will bring to the Sun n' Fun, and one that's in the process of being built.

"I wanted one and I have one," he said. "I'll soon have two. Once the second one is done, I plan to drive it and fly it across the country."

The craft he will bring to the air show was built in 2005.

He said he is more interested in building a racing machine and isn't interested in mass production of a new kind of flying machine that will change the face of private transportation.

"I'm much more steeped in rarity," he said, "than I am in commonality."
