Re: Partly stating the obvious - SANs are I/O bound
I get over 5GB/s max with an average of about 1ms latency on reads right now from an all flash array. Writes are a bit slower with an average of about 5ms ..... I can live with that considering its only going to get better over time.
Why replace what works?
I have an older Toshiba 52inch DLP 1080i TV its about 9 years old. I may just now have to replace it after it is making an audible electric arcing sound. I managed to keep it alive an extra two years by just swapping in some 50 cent resistors when it fried. If I am lucky maybe I can resurrect it again with some more cheap parts and if I can it will stay as long as I can keep it running.
I could be wrong but I am pretty sure some of those systems above it are quite a bit cheaper as well.
Re: Can be the most intense game ever.
I remember when my corp decided to leave our wormhole, Real life got in the way and we were not active enough to stay and make it work so we evacuated our POS, it was a several day effort for 3 or 4 of us scanning for low or high sec wormhole exits all while trying not to get in a fight and blown up. We did have some hairy moments trying to get the POS out but it was also exciting. We did manage to get everything out from months of being in there with minimal loss but when we finally took down the tower and had to hide out to get it out it was down right frightening.
Re: False sense of achievement maxed out...
Thats what I remember of EVE as well I wish I still played it but real life has kept me from it. I used to love the late night wormhole fights or doing incursions sadly none of the guys I used to play with still do it but I would love to get back to it eventually and start to build back up a small corp.
Long from dead
May I remind el reg of this monster
Re: Nothing short of amazing
True, but you must consider Amazon too is now considered a VLC with over 100K employees granted much of them in sales fulfillment etc but quite large as well.
Re: Is this the future?
Tape is not on the way out either. I can still store TB after TB on tape that I dont have disk for. LTO 8 is planned for 12.8 TB a tape uncompressed. 2.5x compressed. Also remember many people cannot nor will not save their data in someone elses DC which could one day randomly shutdown.
People have been calling tape dead for 10 years and it just keeps goin.
Re: Squid to the rescue?
Sure you can. We adjust ours to cache things of up to 1GB since often we download the same updates etc many many times. Its nice when you look at your reports and see you had like 50GB of traffic in a day and only like 30-40% was not from cache.
Also you can use squid with one nic long as it can handle the traffic no need to have two or more if you dont need it.
Re: interesting, but ...
Infiniband already has extremely low latency so it will still be much better than fiber channel. Course we are expanding our fiber channel kit not reducing it here. Talked about doing infiniband just never given time to really look into it.
They forgot to mention the reason the water was purer in beer in the middle ages was the BOILING of it.
"A pox on both your houses."
Its the fault of all the retards in government. You have two sides unwilling to negotiate on anything. One side claims they are negotiating by demanding they get only what they want.... and the other the exact same thing. Its all their faults and anyone who refuses to see it is just a blind partisan unwilling to look deeper than the news headline on their favorite news channel.
Re: claim != evidence
Re: claim != evidence
Considering they are used by the DOD and other 3 letter agencies I would count that it is as its a requirement in many instances.
Pure claims to do 256 AES and heavy de-dupe so you appear to be wrong.
Sweet I have been looking to get my company to get a multiple GB/s internet pipe to match our storage transfer rates vs our 45Mb internet connection now. The "cloud" is not some magical all fixing thing. Just like most technology it has its place in the world but does not solve every problem.
Until your on a plane or in a place with no internet service the cloud is great!!
Re: cheaper than a PC?
That was the only thing I was thinking, why not build an ok pc and put 32 linux vms on it same concept still pretty cheap if you only went with like 128MB per vm you still only need 4GB of Ram sure disk i/o would be an issue but as he said its not fast on the pi cluster either. Neat idea and all but i guess the cost conciousness in me says use a spare pc with ESXi or KVM and do the same thing without spending anything most likely.
Re: Fix these silly benchmarks
yep straight from Avere. Took 32 nodes. What does that cost?
"Results were achieved during testing of a 32-node cluster of Avere FXT 3800 appliances using the SPECsfs2008 NFS benchmark, which showed the system achieved a record-setting combination of 1,592,334 ops/sec throughput and minimal latency of 1.24ms overall response time (ORT)."
Fix these silly benchmarks
Most of these are in no way directly comparable. They need to at a minimum list the number of nodes and MSRP as it took to achieve the results. I mean an Isilion S200 needs 56 nodes to beat an oracle 7420 with 2 nodes. I cant imagine their costs are even comparable. They need to always list the nodes, MSRP, and like a dollar/IOPS number to make these things have any meaning at all.
Re: The biggest problem we had...
I agree 2.6PB is a lot to keep up with but if you compare their controllers to other vendors they put pretty extreme horsepower in theirs. Sure I am not sure if I would trust it either at that level but we are using the 7420s with 4x 8 core cpus (10 cores are available) and 512GB of Ram per controller as well as another 1TB of flash cache per controller. You can go up to 1TB of RAM in each head with the 10 core systems. I cant think of any other storage controller I have looked at recently thats even close.
I dont know who wrote this article. We use our ZFSSA's for FC but it supports NFS, CIFS, and iSCSI just fine as you said as well as infiniband. For the price we tested several other storage vendors and in ease of use and performance it beat or was on par with everything including the VNX line and was cheaper. Not to mention if your using it with Oracle DB and ASM you can get Hybrid Columnar Compression which is only available on the exadata or Oracle DB with a ZFSSA.
Re: battery cooling
I cant speak to this particular battery but in many aircraft its just a small cooling duct that enters the back of the part from the air conditioning system. They are not always very big. That being said though AC doesnt generally run on the ground and it may just be a small ducted cooling fan which doesnt help a ton if the area is already 35C+
Well I will add a caveat to your comment. Commercial airliners are mostly yoke though the C-17 made by Boeing is a stick but yes its still between their legs.
640 light years away for all we know it could go tomorrow and we wont know until 2653ish. Kind of amazing to think about.
Re: Apples and oranges..
Ok then build a drone that flies at 120,000 ft. Not many other planes can do that, and most of the time spy planes didnt actually enter the countries airspace because at that height you usually didnt need to, to see what you wanted to see.
4 of these loaded out with 4TB drives would put you at just less than 1PB Raw in 16U make it 5 of em to put you fairly well over as each holds about 240TB RAW. Not sure if they offer 4TB yet we ordered ours with 2TB and 3TB disks.
Yes quite well aware and most crappy USB 3 controllers are lucky to even burst to 110. Most of them suck I have ran 3 usb 3 drives at the same time and could barely get them to 150 aggregate.
How about a few devices that come close to maxing out 3.0 first. I have yet to see much more than 80-90MB/s on my USB 3 hard drives.
People dont even notice the troll face anymore...I is depressed.
If people are so dumb they believe it will end we should offer to fly them all to a "Secure Cave" (With no air ducts) and lock them in to save them. Gene pool greatly improved.
Re: So far...
You can change the crappy picture its just not easy to find its under personalization but only if you go to it through the sidebar not through control panel... sorry I dont have my laptop in front of me to look but I think that is it. Yes its a bad design. Yes the wireless status totally makes me mad. I personally go straight to the desktop, only use the search to launch an app, and have yet to look at a single gadget/app whatever the hell they are calling them. Only thing I "like" about it is that it is faster to start and shutdown than even 7 and seems to be slightly snappier in some ways that 7 on the same machine. I dont plan on going back because I can deal with the annoyances personally but no way would I ever think about recommending it to deploy at work.
Never heard of Magnums I guess?
Quite a bit larger and fit just fine..... But as someone said above they will just move productions. Idiot Californians always screwing themselves by remove tax money.
As typical the government contorts the laws as they see fit to fit their own goals. The rule of law has no meaning anymore because it means what they say it means at the time they need it to say something, to them the meaning of a law is changeable at will.
Re: Why do we actually still need a SAN?
And if you need several hundred servers in 6-8 racks... tell me how you do that exactly with DAS. You cant, SAN is the only good option. Not everyone has those requirements but we do and SAN is our only option.
Re: Say what?
I actually read a citrix white paper I think it was where they claimed all kinds of insane savings.... if you read the whole thing at the end the summary mentioned most of the savings was actually outsourcing not the VDI itself. We could never make the math come up in any way that saved us money when we already had a good system management system (altiris) and good processes.
Just do it
I may be a yank but I will comment on what I have seen. I have worked on C130E/H models. The later H's were a dream maintenance was fairly easy and the great thing being they required almost no training from the E models. The J's have a few differences but they are basically the same plane. For that alone you will save tons of money on maintenance training and more so because there are already some in the british fleet. C-17s I have been told by collegues are equally reliable and modern. I dont see how any beancounter could take a known platform such as the C-17 and C130Js and justify that against an unknown airframe with unknown problems requiring a lot of training and support. For the price of one A400 you can get pretty close to buying a C-17 and 2 C130's with minimal training and the ability to be supported by other air forces when needed (which can be a life saver from personal experience). It seems like a no brainer to me.
I downloaded 2 just getting an update for my GPS unit and 500MB for SP3 and Im half way there.... anything less than 15 shouldnt even be considered but if im paying 60 a month for slow ass service i should at least have no download service
they had tons of ncos flying planes if i remember correctly and they did a great job.
they are not flown by robots
they are flown by pilots on the ground who can in theory fly multiple uavs at once and when they need to go to the restroom or the end of their shift another pilot takes over. The other reason you will see uavs replace manned combat aircraft eventually is the fact the plane is already capable of doing more than the pilots body can handle. I worked on f-16s for the usaf and they had g-limit switch overrides only to be used in extreme emergency because the plane could pull g forces that would def cause the pilot to blackout but also possible cause structural damage. In the future they will build these planes for higher g tolerance from the start because the pilot is no longer your limiting factor...
i know the difference
and you said it yourself PCI-x cant saturate a 10gbe card your assuming you have no HBAs etc sharing the bandwidth and the medium... they didnt get the bandwidth they were expecting because they are the idiots thank you very much.... sorry i put 10GB instead of GBe ooops my bad for mistyping.
