SLC is ~10x the IOPS/GB for random writes compared to MLC, reads are generally only 20-30% faster.
Why write anything? Include the full expanded content from the MS KB article for the update, they generally run 1-5 pages each if printed on 8.5x11/A4
I have never seen a smaller version ssd have a better IOPS number than a larger one.
I have, plenty of times, SLC has better IOPS/GB than MLC and within MLC eMLC has better IOPS/GB than tMLC. So for a given number of dollars the smaller drive will have better performance.
Crucial M500 480GB = $240 or $.50/GB
WD BLACK SERIES WD4003FZEX 4TB = $260 or $.065/GB
Seagate NAS HDD ST3000VN000 3TB = $139 or $.046/GB
prices are current at newegg
The HDD's are around 10x as cheap per GB.
LOL, only to internal customers =)
Yes, I've heard of Xen, and I've even run it in production, both Xenserver and Oracle VM flavors, and both sucked horribly. Back when VMWare tried the v.Tax I contemplated switching to KVM using RHEV but Redhat took almost 30 days to even get me access to a RHEV download by which time VMWare had backed off on their pricing.
As to the crack about redundancy and scalability, I've got a better uptime metric than any cloud provider, zero unplanned downtime in the last 5 years (vmotion + svmotion makes replacing both hosts and storage a breeze) thanks to redundant generators, UPS, chillers, and internet connections.
AWS is expensive, I can provide the equivalent of an m3.large reserved instance to my users for 1/4th the cost over 3 years, if you ammatorize my infrastructure over 5 years (which is what we've actually been doing) then it's almost 1/7th as much. The only places where AWS makes sense is if you're a quickly growing startup, have a VERY bursty workload, or you're so small that you can't justify 3 hosts for a VMWare Essentials bundle.
It's not a rumor, they showed a start menu + live tiles demo at BUILD this year.
My total benefits put me in the top 25% of industry average for my position and region (systems engineering manager in the midwest). If you're consistently making below industry average then you are either a very poor negotiator, your skills are below average in value, or you value something else about the jobs you take more than monetary compensation.
Or, you know we could negotiate a salary that we are happy with given the job descriptions we are applying for. Since I make between 2 and 3 times the median wage I'm ok with answering some emails off hours or waking up to a page once every 6 months due to a system problem. Then again I'm a tech lead and hence management so I'd be exempt under just about any rules =)
No, corporations exist to protect the OWNERS, not the executives or the board. In criminal cases the government is perfectly capable of prosecuting the individuals who committed or ordered others to commit crimes.
So does this finally mean we'll get Simultaneous voice and LTE/SVDO back? Because all the current generation Qualcomm processors lack dual radio paths for some reason, this despite the fact that the previous generation had it. I have to assume it's because they used so much power/transistor budget on 'more cores!!!!' that they didn't have room for an RF design to accommodate features that are actually useful.
Considering I actually have 600A 480V service in my datacenter and can go and physically grab the cable and note that it is significantly less thick than the line coming down from the fuel pump I used this morning I'm not sure where your theory crafting is coming from.
480V 600A cables are smaller in diameter than current gasoline lines and probably not that much heavier per meter, though that would take ~20 minutes to fill a 100kw battery instead of 3-5 minutes for a gasoline fillup.
