Stop the US daylight saving madness!

How does it force you to change your schedule?

Because I have to get up an hour earlier and pretend 8 AM is 9 AM with the rest of the borg. 8 AM isn't 9 AM regardless of legislation that says it is.

I think it would be a lot easier if you just went in to work earlier if you want more time after work. That way the sane among us don't have to put up with this groupthink game of make believe twice a year.

Well...maybe 1000 was a bit much. LTO2 is fast. But the speed increase by using disk is significant.

What I speak of is a virtual application called CDL (Clariion Disk Library) that runs on our Clariion arrays. They use scsi disks. These devices range in size from 73Gb to 500Gb and are grouped as necessary to allow CDL to emulate the entire range of processes of a TLU. A full size Clariion cabinet will hold several hundred of these devices. CDL does not require a very large number of them.
You are correct though...all this is for short term storage. For DR purposes, these backups to disk would be stored on physical tape volumes on the backend where a real TLU is attached on the network....usually an NDMP setup that has some LTO2 drives partitioned off for use by the CDL.
After the tape backup is done the CDL allows the expiration of the virtual tape volumes for re-use by the front end processes.

I remembered working a job that was 8 to 5 and you did not walk out at 4:59pm either. At the time, I lived in Indiana and on the first day of Summer, it didn't get dark until around 8:30pm. However, sunrise was around 5am. The company did not have flex time. I started work at 8am, 3 hours of daylight already gone. I got up at 6:30am. If it didn't get dark until almost 10pm, that would have been nice especially going to play golf.

Today, it doesn't matter as much since most companies allow for some sort of flex time arrangement. Some days, I am out a 2pm and on Fri, I am out around 9am.

This numbering scheme is a human convention; whether we call a certain time of day 8 or 9 o'clock is arbitrary. In some timing schemes, in some cultures, the day begins at sunset or sunrise, not at midnight. Most people adjust to getting up an hour earlier, or an hour later, with no serious side effects. You seem to think that, according to the watch that God wears, standard time is the "real" time. But it is just a convention, just like DST.

[-YYZ-]

I like DST, too. I think we should stay on it all year round.

[-YYZ-]

Yeah, I think most people in the industry didn't really believe the US gov't could be stupid enough to actually go through with making this change to the start date of DST with so little notice. Of course, you can never go wrong in over-estimating the stupidity of people in general, and the government it particular.

[mysterio]

Real time stays the same all year around.

Make believe government time switches annoyingly back and forth an hour twice a year.

That's how you tell real time from pretend time.

Go to work an hour earlier in the summer and leave the sane folks alone.

Why bother emulating a TLU, at all? For immediate backups snapshot technology would make even more sense, with less impact on system performance. Of course, it does require certain new software solutions as well, where you could use a virtual TLU with your existing tape-oriented backup software. I guess I just answered my own question, eh?

[Bloody Sam Roberts]

One of the advantages to emulating the TLU would be that most backup software that is getting "spoofed" allows the user to specify a greater granularity of backups than taking a snapshot of an entire filesystem.
In fact, some of our customers do use snaps and clones and then run scripts to back them up to tape....but the virtual TLU provides a bit more flexibility.

[BlueMondaySkipper]

We have a CDL700 with about 12TB of disk installed.

I just ran a test last week and my test backup (6 concurrent streams of 400-700 GB each) ran about 2X the speed of the same job to a single LTO2 drive. The CDL is configured to look axactly like the real library/drive I'm comparing it to.

[Bloody Sam Roberts]

I did some cursory training on CDL when it first came out a few years back. A nice looking interface...cool product.

It is another triumph of urban thinking over common sense.

[ctdonath2]

Quite. As if time really is subject to simple majority votes.

Funny how urban centers, nurturing a people clueless about how the physical world works, turns out so many "environmentalists".

The metric system is pretty simple. All you need to know is how to count to ten.

And divide to 2.5 and 3.333333333333333333333333333333333333333333
