Proposed Disk Array With 99.999% Availablity For 4 Years, Sans Maintenance

silas_moeckel Re:Not my anecdotal experience (255 comments)

Well you can probably double your density moving to non hot swap 3.5's, making double the drives even on space. Now if I were going to do that I would mirror the raid sets anyways since power consumption of near line drives is pretty minimal.

Never seen much of a use of enterprise sata, I do use a lot of SAS with dual ports to separate raid controllers.

Proposed Disk Array With 99.999% Availablity For 4 Years, Sans Maintenance

silas_moeckel Re:TLDR; 2D arrays wit a ton of spares are reliabl (255 comments)

We do just that, when it gets down to 1 hot spare it's an emergency service and we replace all the failed units. This does not happen very often and tends to be just that a bad batch.

Proposed Disk Array With 99.999% Availablity For 4 Years, Sans Maintenance

silas_moeckel Re:Power Costs (255 comments)

Well since they are not supposed to need to be hot swap you can get 12+ drive into a 1ru chassis with redundant power and a fairly beefy server. That is 3x the density of traditional 4 up front 1ru. Expanding to 2ru gives 12 hot swap 3.5's or 24 2.5 still 2x the density in 3.5's for non hot swap. Potentially even higher with 2.5's, though highest I find is 88 hot swaps in a 4ru or 22 per ru coupled with a rather beefy server.

Proposed Disk Array With 99.999% Availablity For 4 Years, Sans Maintenance

silas_moeckel So they figured out raid z 3 with enough spares (255 comments)

To last all of 4 years, and need nearly as many hot spares as data drives. I guess the academics think they know something yet again. They took some dubious failure rates (backblazes use whatever is the cheapest consumer drive at the time and eventually stop buying the really bad ones (seagate 1.5 and 3tb looking at you)) and a rather optimistic transfer rate (200MBS) that assume all sequential reads. They failed to account for back plane, controller, and power assuming that those never fail. By their numbers you might as well run mirrored raid 5 or 6 with enough hot spares to make it between regularly scheduled tech visits. That give you the ability to split chassis and controllers along mirror lines. As to rebuilds we have better methods, predictive failure works well, ssd's make great caches while rebuilding etc etc. We also have less centralized options with distributed technologies that potentially scale better.

5 9's is not that hard of an objective when talking about raid sets, the tools have been there for decades. Sure you will never reliably reach it with a single path to anything, 5 minutes is not enough time for even a staffed site to remedy any outage.

Justice Department: Default Encryption Has Created a 'Zone of Lawlessness'

silas_moeckel Re:Security is a yes/no question (423 comments)

Incorrect, if they want access to your encrypted information they may get a warrant, you can then defend yourself against said warrant by contesting it, a judge might hold you in contempt for not giving up the keys (that is a contempt to try and make you comply not a punitive one so is only supposed to be until they figure out your not going to). This is not what they seem to be worried about.

They are worried about not being able to just take or use secret courts to access whatever they want. Pervasive encryption means they can no longer get all the info they want from the middle men who tend not to fight back much, use national security letters when even the secret courts wont give them a warrant. Having to use actual warrants served to the people effected who might fight them and use the media to shame them means they better have a good reason vs just fishing. You can also devise hardware and protocols that put a time limit on being able to decypt things that would limit the time held in contempt (simple one is a chip that holds the keys and erases them if it does not get a passcode every so often or looses power a basic extension on existing TMP).

In short you can have secure encryption that the government could force you to let them access. It's messy, time consuming, and does not always work.

Uber Capping Prices During Snowmageddon 2015

silas_moeckel Re:Driving ban (154 comments)

If it's an emergency that is what the ambulance is for. Sure you can take your own car it's not suggested.

At least around me fire and police are happy to give emergency workers a ride in. Hell even seen the plow guys do ti.

Researchers Tie Regin Malware To NSA, Five Eyes Intel Agencies

silas_moeckel Re:A call for Write Protect (94 comments)

Trust as in how do you know jumping through those hoops stops the NSA? Maybe the use the secret courts to require a backdoor, maybe they alter the chips themselves.

The NSA etc needs a clear directive by the president and congress that this is not ok. As long as they get only a minor slap of do not do that again it will not stop.

You can just connect any of the many SIP or IAX trunk providers to software. The main issue is battery life sucks.

UHD Spec Stomps on Current Blu-ray Spec, But Will Consumers Notice?

silas_moeckel Re:How many people have this setup to start with? (332 comments)

I have a 10+ year old 1080 flat CRT no HDCP support hell it's got DVI not HDMI. Screen looks beautiful the whole were going to obsolete your gear because you might pirate our content BS was the last straw for me. The content got pirated anyways and pirated content plays just fine on my "ancient" TV, flankly it works better than the store content no unskippable 30 minutes of ad's and I can trans-code it for any device I care to.

UHD Spec Stomps on Current Blu-ray Spec, But Will Consumers Notice?

silas_moeckel Re:I won't notice (332 comments)

So I'm supposed to by some low density read only plastic disk with a movie on it with heavy DRM. To put into a player that is beholden to the media companies who happen to have a horrid history for security.

I'll stay with downloaded content, aside from an unlikely unrecoverable raid 6 failure they content is mine and I can do what I like with it forever. No I do not want to rent your content, I do not want to have to view it on approved displays (I'm still using a pre HDMI 1080 CRT 10+ years old). I do not want to be beholden to your licencing servers allowing me to view something. I will format shift and re-encode my content as desired (thank you plex). I do not want to have to use your player app and/or use your god awful myopic library app. I will not be forced to watch your previews or use your "cool" custom menu system. I will use whatever subs I choose including the original language translation vs your horrid dub script.

If somebody will let me pay retail pricing for that, with the content I want to watch I'm happy to pay for it. Frankly even the stuff I buy for the sake of owning the dvd box set etc I never actually watch from the included media.

Government Recommends Cars With Smarter Brakes

silas_moeckel Re:I have an even better idea (304 comments)

We did have that right early on, the anti car people (aka buggy whip association) pushed to get that snowball rolling to put ever increasing restrictions and idiotic ordinances in place.

You do not have an effective freedom to associate if you do not have the freedom to travel one requires the other to be effective.

As to how to fix it I do not have a good answer but right now the balance is off.

Eric Schmidt: Our Perception of the Internet Will Fade

silas_moeckel Re:No thanks. (228 comments)

I split the difference I want my world to work for me. I do not want others to see me as data to be sold and traded. To that end my home automation is local, it sources data externally for weather forecasts and the like. I want the lights to come up and light the room to my preferred levels when I walk into a room. For my music choice to follow me about. For my door to unlock when I get home. I want to track my power usage with a good amount of detail, already finding that there is value in this data from spike loads changing when things turn predicting failure etc etc.

I'm already seeing that I want things to be more connected, to different levels. I want my TV to be fully IP it consumes information and gets replaced in the 10-20 year timeframe. My dishwasher or dimmer I want something secure and dumb with the brains in a smarter device. Turning something on and off and relaying sensor data does not take much local brains. I also do not want to have to replace my light switches every generation.

Google Plans Major Play In Wireless Partnering With Sprint and T-Mobile

silas_moeckel Re:Layers (101 comments)

It's baked into the MVNO's, to my knowledge none of the MVNO's upcharge for domestic roaming.

The economics are thus Sprint etc have huge expensive retail outlets that pay layers of commission. T-Mobile is sitting about a gross profit margin of 50% Sprint a little less. Ting is reselling Sprint and soon t-Mobile and making a profit and I doubt that Sprint is selling to them at a loss.

If it takes off I can see them trying to reign back the MVNO's but that gets more complicated if the phones work with all carriers. It's really making it look like the transit bandwidth market since you have at least a handful of company's that can support the back end competing for most of the market. Sprint tries to jack the rates preference t-mobile if your big enough other carriers will deal as it's a huge chunk of revenue for them to set you up as a MVNO. To the MVNO it's a question of ranking the carriers cheapest first.

Google Plans Major Play In Wireless Partnering With Sprint and T-Mobile

silas_moeckel Re:Layers (101 comments)

You do not need all the carriers just 2 to get roaming to all of them, Sprint and T-Mobile gets you everything.

Apple and Google seem to be coming from entirely separate directions, Apple did a deal to make it a fashion accessory and hype via the AT&T exclusive. Hell the MVNO have to fight to get apple products allowed for their use. Google fought to get one phone to rule er work with them all and undercut the carriers pricing. Sure it seems like they want your data to mine. Apple sells trendy hardware Google sells your data very different priority sets.

Google Plans Major Play In Wireless Partnering With Sprint and T-Mobile

silas_moeckel Re:Layers (101 comments)

While not forcing them to converge Google looks to be leveraging the carrierlessness of the nexus line, where it can connect to CDMA and GSM networks simultaiously. Ting and others have already announced this feature. And it looks like more phones will support this after Google forced the carriers to allow it lest the nexus line not work on them.

silas_moeckel Re:Nothing new here (101 comments)

I have plenty of 20 somethings that switched and cut there bills by 2/3's or more. If you want unlimited everything for a single phone republic wireless tends to be the better choice.

Google can afford to buy a network or two if they wanted, that would position them to data mine all those 20 somethings constant phone use.
