Comment Re:How many days will it take . . . (Score 1) 219

That's why the redundancy design of disk arrays like IBM's XIV (and others) are so necessary with large SATA drives.

Rebuilding a single 8TB drive to another single 8TB drive in a raid array is dangerously slow (odds of a secondary failure are high). It will also have a long negative impact on array performance.

But if your rebuilding redundancy from a failed 8TB drive across a system containing say 72 of these drives with (at least) triple redundancy of any given extent, you'll be just fine and struggle to notice a performance hit.

Basically, large SATA drives don't belong in classic RAID designs. You want to massively distribute IO & redundancy to overcome the per disk bandwidth limitations.

"Tesla is getting legislated out of existence in most places."

Please explain.

The laws denying auto manufacturers from selling directly to consumers are ancient & GM blamed them too some degree for their bankruptcy back in 2008.

There are also laws forbidding movie studios from owning movie theaters, based on similar reasoning.

These aren't NEW, they aren't getting 'legislated out of existence' they failed to build a business model that fits the current laws. Either they modify their model & sign up dealers (boo!) or continue to fight this in court (hooray!).

Comment Re:Relates to K-Mart purchase (Score 2) 137

Sears Holdings isn't a retail company, or an IT company, or a realistate company, they are a hedge fund trying to squeeze out all the possible paper value from their assets. So that they can eventually convince some other sucker to buy these assets.

This is a continuation of some rather silly decisions that they've been making for some time.

Comment Re:Nor surprising and won't matter. (Score 3, Informative) 121

Regarding Ford specifically.

You'd be surprised at the scale of their IT organization (as someone who once worked in Ford's datacenter).

They already have their own 'internal cloud' and have for some time (before 'cloud' was a 'thing'). The only thing different here is internal provisioning processes vs. Amazons credit card & go plan.

The cost of Amazon doesn't make sense, when you already have a pair of tier 1 datacenters and an IT organization more then capable of maintaining it.

Ford already HAS servers that won't be 'clouded' any time soon, so they have every bit as much justification to keep on doing things internally as Amazon would. And doing things for themselves gives them more control & likely better costs.

Comment Re:PVR (Score 2) 146

Is that a limitation of the PVR API, or the PVR plugin your using?

If it's available within the API, then I'd wager it's coming sooner rather then later, if the plugin is actively maintained.

That's the beauty of implementing the backend client in a plugin, they can be updated far more regularly then XBMC proper.

Comment Re:Busy databases (Score 1) 464

Possible, but still unlikely: unless your doing odd workloads or crazy overloading your host servers.

Most SANs are themselves rather oversubscribed, go look at the fan in ratio of your disk array. This is honestly what makes a SAN viable, otherwise you'd just plug all your servers directly into the disk array.

Disk IO tends to be bursty, which lends itself well to over subscription at the network layer.

In most cases, it's the spinning disk that is the physical bottleneck.

Comment Re:Busy databases (Score 1) 464

As a storage admin, I gotta say this is usually not the case in my experience.

Most 'busy' databases are either not as busy as the app folk think, or the bottlenecks tend to be inside the server/app not the spinning disk itself.

If you really DO actually need dedicated spindles for a database or two, you can still accomplish this under VMWare, thus making the entire point moot.

You can toss app owner in their if you want, I wouldn't though.

I've worked at places that stick strictly to a functional naming scheme & those that used comic book characters and the like.

I gotta say, the silly comic book character names function to keep new hires less valuable for longer. It's confusing to everyone but they guy who's been there since they where built. Then again, keep in mind I've only really worked in datacenteres of fortune 50 sized companies, SMB systems might be easier to track w/silly names.

Comment What does OP do? (Score 1) 506

OP is very light on detail about what type of job he's even looking for.

Is he a programmer, a system administrator?

What, prey tell, does OP want to be when he grows up?

These things are the FIRST questions we need answering, before we start looking at specific technologies (i.e. MS vs Open Source).

The roku box may cost $99, hey I don't even need it as I've already got a Wii. However the added equipment required to cleanly integrate either of these into my whole house distribution system EASILY doubles that cost. I already have a full featured Linux HTPC that can be viewed or controlled from nearly any room in my home. Netflix simply refuses to integrate into my existing setup for a reasonable cost therefore I refuse to fund them.

FCoE...

A solution in search of a problem. 10GbE ethernet is really very nice. FC (and FCoE included) have a history of poor vender interop.

So by using FCoE you get the worst of both worlds, 10GbE with vendor lockin at the storage level....

So... NFS anyone (or I guess iScsi)?

Only time i've ever used FCoE was as a WAN tunnel link for asynch rep.... not seeing any other value for this anytime soon.
