With APC it's the SmartUPS RT series and up (VT, large Symmetra, etc.) that are double-online; the SmartUPS and SmartUPS XL are line interactive. Another key is if it does that buck/boost thing: that's line interactive. A double-online never needs to do that because it doesn't pass line voltage directly to the load.
As far as I can tell, it's the no-contract "Even More Plus" (which appear to be $10 less than the 2-year term ones) and you choose the free SIM card instead of a phone.
Sure, the 2800 and 3800 ISR series can take full tables easily. You can get a 3845 starting at $10k. NM-1T3/E3 module is about $6k. Both the 2800 and 3800 take DDR-266 ECC SDRAM (except the 2801); don't feel the need to pay Cisco's prices for commodity RAM if you really don't want to. The 3845 is recommended to handle up to 2 DS3's. According to people I've asked, you can push a 3845 to 100-150 Mb/s. You can go as low as a 2811 ($2k) and still take full tables, but only at fractional DS3 speeds. I would guesstimate a 2811 is good to 10-20 Mb/s, Cisco recommends it for 4xT1.
Also, consider that some ISP's will include equipment bundles with circuit orders if you haven't already explored that angle.
They do, but it seemed like it was always broken and said "usage not currently available" until weeks later. It was also generally wrong; they said you get X because you have Y speed, but the meter always said 150GB. It wasn't very helpful.
Don't fret, AT&T is working on making DSL users pay for metered service. Here in Reno, NV (and someplace in Texas I can't remember) they are doing a billing trial thing where they cap your service at X GB depending on your speed tier and charge $1 per GB if you go over. The day my parents got a $400 bill I helped them cancel it and move to anyone who wasn't AT&T DSL. If it's "successful" they'll probably start rolling it out across their service territory.
I can couch for this. POTS ATT = $30 a month after all the "required" fees and taxes are added. Bare minimum, no long distance, no caller ID, local calling only, no options whatsoever.
Mine (AT&T Nevada, not Vegas which is Embarq land) is:
Monthly Service - Dec 20 thru Jan 19 1. Residence Flat Rate Svc 10.83 Line Sharing Basis Surcharges and Other Fees 2. Federal Subscriber Line Charge 4.95 3. 9-1-1 Emergency System.25 4. Federal Universal Service Fee.60 Total Surcharges and Other Fees 5.80 Taxes 5. Federal.50 6. Local.82 Total Taxes 1.32 Total Plans and Services 17.95
Plus $30 for DSL. As to why I have a landline, yes I have a cell phone, but I don't want to be available to everyone and their dog 24x7, plus where I live has crappy cell reception.
So just buy a few 750 gig 2.5" laptop sata2 drives - they're $150 a piece, and the 5400 rpm run cooler than the more expensive 7200 rpm. The 1TB ones are still pricey at $250, but they'll come down in price.
Well, I was referring to 15k 6G SAS drives being scarce above 300G.
- Most of us forget that the first single-point-of-failure is probably a cell tower. Yep, you might have two or three that can serve you, but if the backhaul from your tower is fritzed, you might have to wait until you get paroled from that tower, and move one to one that isn't hosed.
- The next single-point-of-failure is probably a metro area uplink for your carrier. I don't know for sure, but I suspect redundancy here is not universal.
- God forbid your carrier is architected like T-Mobile, or your single-point-of-failure is either a GSM service that has to be responsive or your phone is doing rock imitations, or a similar CDMA. I hear CDMA doesn't have the same architecture, but if your carrier can't authenticate you to the network, u b hosed.
In practice, all three of these happen far less frequently than RIM has outages.
Cat 6 became the bastard standard; turns out it was only good for short runs of 10GbE and 5e could already do gigabit at 100 meters. I'd personally stick with 6a (the new 5e) lest 7 share the same fate as 6 for whatever comes after 10GbE. Remember when they said we'd be using fiber to the desktop for high speed Ethernet? Well, they keep coming up with ways to make good ol' copper stay the course.
Sounds like they're targeting the iPhone, only from AT&T.
Company with fanatical users (Apple) creates a product that is data-heavy. AT&T must have seriously botched their usage projections, not bothered to do any, or figured they're just foist extra fees on their customers when it started to be a problem because they know anyone wanting an iPhone can't jump ship to a competitor.
Appliance do not have a bad reputation. Now if you buy a cheap audiovox or other cheap brandname appliance then your experiences may vary. However, that being said you buy a real brand and they last almost forever.
Crap, I have a 1998 Mitsubishi DVD player from the early days of DVD that's still in use today. It works just as well now as it did new. The only thing it lacks comparatively is progressive scan output.
To go even further, there are line cards for the very expensive Cisco 6500 series switch that put gigabit ports in groups of 8, so you may have a 48-port card, but you certainly can't utilize every port at full rate. This is not a phenomenon that's limited to home user grade equipment.
HP's switches are practically free compared to Cisco's pricing (forgetting the rape that is smartnet) for functionally equivalent hardware. Throw in free firmware updates and a lifetime warranty, it's a great deal. Here's to hoping they leverage some of that IP and come up with competitive big-iron stuff that compares to the likes of the Nexus or 6500.
A 12" slab with mesh (what mine is) does have a higher load bearing capacity that a raised floor, though. Equipment weight and load distribution is completely a non issue.
You're missing the point, you don't need to be able to get up to that number at all. That's why the "up to". DSL, for example, can train down to a slower speed due to line quality and/or distance which have nothing to do with your usage profile.
Business class DSL and cable where I am still carries the "up to" tag on the speed no matter how much you pay them. I can attest that I dropped AT&T business DSL (installed at my parent's house for 9 years) when they started charging $1 per GB transfer because they decided this is a good test market for such things.

Raid is quickly becoming obsolete, both due to better database partitioning schemes, larger capacity single drives, and to "too-good" quality control.
Meh, still hard to find fast SFF SAS drives larger than 300G at the moment.
Hard drives fail. Same as anything else mechanical.
You didn't build a RAID out of drives from the same manufacturing lot and age, did you?

Windows Mobile locked down? How's that? I can't recall ever having a restriction running binaries and modifying my WM5 and 6 phones.
How about we just don't give them money this time?
Out of morbid curiosity, I do wonder what that would sound like.

It looks like a tube with holes punched in one side like those used for duct smoke detector air sampling.

No it wasn't, as far as I've ever read or heard about. I'll let someone else find a source or correct me.
Holy crap. This surely must be satire or stolen from The Onion.
