spoken like a lazy storage admin
This article safely reinforces the worst prejudice of storage admins, which is the belief they can do their job and remain ignorant of the applications that run on their systems.
I'm a DBA (Sybase, Intersystems Cache) and a storage admin (ZFS, NetApp) for a cloud company. As a vertical market software vendor, I also deal with our premises customers' myriad other storage systems (EMC, Compellent, Hitachi, etc.). I've seen a lot of good and a lot of bad. The storage system, more than any other component, determines application performance.
There can be a real need for multiple LUNs in a database, even though they ultimately sit astride the same physical disks. Separating data from log I/O in RDBMs is axiomatic. The OS kernel may effectively serialize I/O to a single LUN whereas multiple LUNs have multiple software channels. In other words, you are clearing a software not hardware bottleneck. There could be other considerations in regards cache policies, tiering, etc. that justify multiple LUNs.
One electronics shop was looted, and afterwards counted 32 more HP tablets than they started the day with.
denied the frisson...
or, in other words, piloerection. And it's only Thursday.
The Brits tried to pull a fast one and turn Jerusalem over to the Arabs before they were scheduled to bug out. Didn't work too well. There was considerable animosity between Israelis and Brits at the time. The only reason the latter did anything to benefit the former was Truman twisting their arm.
Why is it every alarmist warming scenario piles on an endless chain of positive feedback loops? If the realy world worked that way, the first dinosaur fart would have cooked the planet millions of years ago. Finally, we have a model that considers a possible negative feedback, and guess what? Things aren't so bad after all.
Maybe you invented the Internet, but I invented computer networks...
In high school I discovered I could get two TRS-80s to talk together by cross-connecting their cassette tape drive cables. The first machine thought it was writing a string to tape, but it was really read by the second machine, which thought it was reading a string from tape. I cooked up a BASIC version of Battleship to demo the concept.
What about FT and BC?
There's also fault tolerance (FT) which is a very high level of redundancy, such that software is unaware of any failure. I'm thinking especially of Tandem. And then there's business continuity (BC) which is like DR but focuses less on the disastrous aspects. I'm thinking near line storage or data replication. The lines can blur but you really need prudent amounts of both. You don't want to fail over to the bunker just because one disk goes bad. And your RAID6 array doesn't help when it's under water.
she's just not into you (and vice versa)
I've always felt I was a lesbian trapped in a man's body.
I need to read El Reg before doing anything else on a Monday!
I was so frustrated by 4.0 performance on my steam driven 3G that I downgraded it to 3.13. Not a hard process, but you can't restore apps, settings, etc. from backup. To stay on 3.13 you have to set it up as a new unit. I lost Exchange, VPN, etc. settings, not to mention Angry Birds progress.
Now I read of relief in sight. Crap.
BTW, iTunes won't let me restore from backup, even after a firmware upgrade because it's a different machine. I think I'll relax and read The Register until I calm down.
When the data you're protecting is all in an object or relational database, the DBMS usually offers another form of replication. Database replication basically consists of replaying the primary's transaction logs on a secondary system. This is an attractive option because replaying transactions instead of physical device I/O prevents many types of corruption and maintains transactional integrity. The secondary system can be used for report generation as well or other read-only uses.
I'm with Jake.
Technically, it might be a verb, but it sounds wrong to my ears. If we all agree to never use it as a verb, eventually (after a hundred years or so) the OED will delist it.
Let's dialog it some more.
I haven't even figured out what a dutch lobster is. Now this!?
I guess your profile would be low if you're alway horizontal.
Once the Web gets deduped, my 9600 Baud modem becomes viable again.
Reminds me of the joke about the Texan who passed away and was too large to fit in a casket. They gave him an enema and buried him in a matchbox.
Forget re-writing history. Try reading history.
The Taliban came after, fought, and displaced, the Mujahideen. The people we armed to fight Russian invaders were Mujahideen. Taliban largely sat out that fight, or were too young.
As a vendor SE, I had the misfortune of attending a meeting of LA Times execs after they all received their Newtons. The meeting was constantly interrupted by, "hold on!...(scribble, scribble)...okay, go ahead...hold on...(scribble, scribble)...". My comment about witnessing the human equivalent to XON/XOFF flow control was not appreciated.
Those in the room with Tandy Model 100s had no problem keeping up. Ah, the Model 100, stalwart of newsrooms everywere, that's a computer you should memorialize.
Tombstone, to represent beloved gear of day gone by.
eBay, Craigslist, or a slow boat to China
How many ToughBooks does Panasonic sell of any model, and how can the thieves expect to unload all that gear? Obviously a pro job, so they had to have an end game. Frankly, I'd be more worried if they spent nine hours playing with the laptops and then left them in the warehouse.
@ all Brits...
Surprised you Brits missed the significance of the red X. Clearly the X is the Cross of St. Patrick and Steve's mug replaces the Crosses of Saints George and Andrews. Hats off, and salute your new Union Jack (thumb-side down, of course)!
All for it.
Parents and pornographers both have an interest in keeping kids away from the stuff. The latter if only because kids don't have credit cards. The former because they bought the damn computer to do homework on.
This kind of initiative is usually quashed by prudes under the misaprehension that a porn-only TLD somehow promotes the stuff.
Need a headcount.
