Linode NextGen:网络

这是关于我们称之为Linode的努力的一系列博文的第一篇:NextGen。在未来的日子里,我们会告诉你其他的改进和变化,但今天我们想让你知道网络的升级情况。

我们正在花费100万美元使我们的网络更快。快得多。思科Nexus 7000路由器。思科Nexus 5000交换机和Nexus 2000 Fabric Extenders。Linode的出站网络上限增加了5倍。出站月度传输配额增加了10倍。

我们正在升级我们的整个网络,在所有六个数据中心。 所有的东西都被替换了,从顶级的路由器到主机连接的交换机。我们已经能够做到零停机,并预计在未来几周内完成升级。

为什么要做这一切? 很简单,我们已经超越了我们的旧网络架构,需要一些能够:

  • 处理我们的规模;
  • 大大提高了吞吐量;
  • 减少延时;以及
  • 在接入/主机层增加冗余度

我们选择了思科Nexus 7000系列路由器,因为这些是思科提供的唯一具有足够大的MAC地址和路由表的设备,可以满足我们的要求。 对于我们的新接入层交换机,我们决定采用思科Nexus 5000系列交换机和Nexus 2000系列光纤扩展器来实现机架顶部的连接。

利诺德-下一代网络

我们在每个数据中心的整个网络堆栈,从上到下都内置了冗余功能。每台主机都与两个独立的结构扩展器相连,并有绑定的千兆链接。这不仅在网卡故障的情况下提供了冗余,而且通往主机的流量在其网卡之间得到了负载平衡。

每个光纤扩展器使用10Gbps链路连接到一对思科Nexus 5000交换机,将其流量负载平衡到每个交换机。这里的负载平衡意味着一对光纤扩展器和一对交换机之间的有效吞吐量为40Gbps。

每对5k交换机都以类似的方式与我们数据中心的两个路由器相连:它们之间有四个10Gbps的链接,负载平衡,同样有40Gbps的吞吐量。最后,每个路由器都有多个10Gbps的链接到我们的上游供应商,也能够进行故障切换和负载平衡。

我们使用的是思科出售的最好的交换设备。 更大的网络容量大大增加了我们对DoS攻击的弹性,而负载平衡和冗余配置意味着硬件故障不会影响连接。

我们还将Linode默认的出站网络限制从50Mbits升级到250Mbits/秒。 你所需要做的就是重新启动以接受这个五倍的增长。 请记住,这只是对出站流量的限制。 入站不受限制。

最重要的是,我们已经将所有计划所包含的向外转移的金额增加了1000%。 这是正确的,包括10倍的转移!

  • Linode 512从200GB升级到2000GB(2TB)。
  • Linode 1G从400GB升级到4000GB(4TB)。
  • Linode 2G从800GB升级到8000GB(8TB)。
  • Linode 4G从1600GB升级到16000GB(16TB)。
  • Linode 8G从2000GB升级到20000GB(20TB)。

和以前一样,所有入境转移都是免费的。

在接下来的几天里,我们将告诉你关于Linode的第二和第三部分:NextGen。我们认为您会发现它们同样令人兴奋。 祝您愉快!

    Wow, this made my day. Low transfer caps was my only gripe with Linode before, but not now!

  2. Author Photo

    Yes!!
    I have been hoping that Linode would do something like this soon. Linode has sort of been stagnating lately, but I had a feeling you guys were working on something big. THANKS!

    10x increase in allocation AND 5x increase in speed!? Linode, you just blew my mind.

  6. Author Photo

    Awesome! WowwwwwwwwwwwWWWWWWW!!!!!!!!!!

    thank you 🙂

  7. Author Photo

    Wild!

  8. Author Photo

    Wow. Thank you!

  9. Author Photo

    10 times? Really! Amazing!!

  10. Author Photo

    Great news 🙂 thanks

  11. Author Photo

    Its times like this I really know choosing linode as my host was the best idea ever 🙂 Thanks a lot for this upgrade!!

  12. Author Photo

    Makes my transfer usage bar when I login to my linode look even worse:

  13. Author Photo

    Damn. My ISP could learn from you.

  14. Author Photo

    I can’t tell you how happy I am about this, I was just about to cancel my account in favour of a company offering more transfer. I was filling in the cancellation form when I saw the Facebook post, so glad I spotted this in time!

  15. Author Photo

    This is exciting news. I’m glad to see Linode isn’t resting on their laurels.

    I’m crossing my fingers that one of the future announcements you mention has to do with storage, and particularly I/O performance. I want to move the rest of my company’s servers to Linode, but for a couple of applications in particular, we need faster I/O than the nodes we tested could provide.

    That said, your product is fantastic, and I never hesitate to recommend Linode to other people. Keep up the great work.

  16. Author Photo

    Wow,thank you linode!

  17. Author Photo

    I’m surprised that nobody mentioned that based on the diagram you run all of Linode on 6 hosts. Amazing job. 😉

  18. Author Photo

    The best this is: I trust linode and I know they can deliver what’s promised.

    Other providers may offer stuff like this, but I doubt they won’t kick you out as soon as you start hitting those limits.

    I’ve been a costumer since Jan/2009 and I look forward being a costumer for years to come.

  19. Author Photo

    I wonder why I was wasting my time and money to other hosting providers…
    One more thanks from me Linode!

  20. Author Photo

    Awesome! We love Linode

  21. Author Photo

    My February cap was almost exceeded (96% of my 200GB quota used), so this could hardly have come at a more opportune time. Thanks, Linode !

  22. Author Photo

    Wow! This is why I’ve been sticking with you guys, there is nobody else that offers this type of service and constantly increasing features. Proud to be your customer 🙂

  23. Author Photo

    Wow, signed up with you guys moving over from dreamhost and it has been a dream – so happy about all of this. thank you!

  24. Author Photo

    Oh well there goes up my uptime! At least it’s for an awesome reason. Thank you Linode

  25. Author Photo

    Thank you guys so much! Very exciting news, can’t wait for the other NextGen stuff.

  26. Author Photo

    Amazing Linode! Thank you very much!

  27. Author Photo

    Thanks, It’s wonderful.

  28. Author Photo

    Hi Linode,

    please add the ability to provision bare-metal servers with fast disks attached. With such an hybrid setup you are going to dominate the market if you move FAST.

  29. Author Photo

    WOW, this is amazing Linode! Thanks for this!

  30. Author Photo

    Sick! Thank you Linode.

  31. Author Photo

    This is super news! Thank you very much!

    “All you need to do is to reboot to receive this five-fold increase.”

    So… when can we expect these changes take effect? We need to schedule our downtime for those reboots. Yummy, yummy bandwidth… 🙂

  33. Author Photo

    Well congratulations linode, you just won my business.

  34. Author Photo

    You may want to double-check with your Cisco support engineer about those FEX-to-5k cross connects. They generally recommend the FEX’s connect to a single 5K. Also, the VCD configuration on the a pair of 5Ks can be a little wonky.

    Best of luck, looking good!

  35. Author Photo

    Wow, this is really nice! Amazing 🙂 Good job Linode.

  36. Author Photo

    Peter:

    We are actually using Enhanced vPC with our 5Ks and FEXes, which is a Cisco-supported topology. It allows us to connect each FEX to two 5Ks, as well as have both 5k-to-FEX vPCs and FEX-to-host vPCs.

    We’ve been using this topology since mid-2012 and it’s been working great for us. 🙂

  37. Author Photo

    Thanks guys! Always had great performance and uptime with linode, and this is a very nice gensture.

  38. Author Photo

    I am so happy I chose linode.

  39. Author Photo

    Das is uber guten.

  40. Author Photo

    Damn glad to be a Linode customer. Thanks and keep up the great work!

  41. Author Photo

    Wow. Thank you.

    Good to be a Linoder

  42. Author Photo

    Oh! Will be opening my account again then!

  43. Author Photo
  44. Author Photo

    Awesome, thanks for the additional xfer! As mentioned, hope it’s in preparation for something like an OpenStack Storage implementation for a CDN, err cloud offering but will also allow for creation of large (inexpensive) persistent and ephemeral disks for their nodes similar to EC2 and Google Compute volumes.

  45. Author Photo

    This is incredible! You’ve just put money back in my pocket. It is totally unheard of for a host to do this. You have a customer for life.

  46. Author Photo

    Once again I become very confused when people recommend anything but Linode for a VPS

  47. Author Photo

    Linode, model VPS ever!

  48. Author Photo

    Marvelous. A great move by Linode.
    Linode Nextgen Rocks 🙂

  49. Author Photo

    Linode is a no-brainer now.

  50. Author Photo

    I won’t get sold that easy… The truth us, bandwidth consumption is possible only when you offer extra cpu and extra memory… Without that, I bet you could offer 100x bandwidth and still no difference in the overall delivery.

  51. Author Photo

    reaaaally great news Linode! Thanks a lot

  52. Author Photo

    The homepage shows the blog post as “March 2012” 😛

  53. Christopher Aker

    @ cralor – fixed, thanks.

  54. Author Photo

    > Linode 512 upgraded from 200GB to 2000GB (2TB)
    Fantastic, great to see you passing improvements down to customers. I knew you guys had a good reputation (which is why I signed up with you) and now I’ve experienced why first-hand, brilliant.

  55. Author Photo
  56. Author Photo

    Linode you are awesome!!!!!!

  57. Author Photo

    I recently scaled back my linode to a 512 and moved the main site to a Dutch VPS hoster that gave me 1GB ram for 1/2 of the 512 price. I loved linode, but its getting too expensive for hosting rails apps that eat memory.

    here’s one hoping for mem increasings, the service of Linode is unparalleld.

  58. Author Photo

    *jaw drops*

    Way to go Linode!

  59. Author Photo

    Interesting. Of course my linode64^Wlinode512 rarely gets to 5% of my current bandwidth 🙂

    I wonder if this new design will allow for FCoE or iSCSI based SAN environments in each datacenter. That could increase resilliency (atlanta47 dead? Migrate to atlanta53 with a flick of a switch!) and might let you scale disk storage (a repetetive ask in the forums; again not something my small needs care too much about).

    Interesting, indeed!

  60. Author Photo

    Great news, Linode latency was already away better compared to my DigitalOcean VMs. Now the 4x price tag is starting to look justified.

  61. Author Photo

    Really stunning. We will move everything from ec2 to linode next week.

  62. Author Photo
  63. Author Photo

    wow, 10x ! Perfect!!

  64. Author Photo

    Is overage still $0.10 a GB or has that been lowered as well?

  65. Author Photo

    WOW! The network is quite fast now!

  66. Author Photo

    Great news! I’m glad to see that there are some big changes happening at Linode. Can’t wait for the other articles.

  67. Author Photo

    Incredible changes, 10x! It’s awesome!

  68. Author Photo
  69. Author Photo

    oh, my aws will be discarded.

  70. Author Photo
  71. Author Photo

    Was wondering just yesterday, when do we hear about whats inside the big boxes that were delivered last month …
    now need to wonder, what do i do with this extra bandwidth..

    “wonder”ful linode..

  72. Author Photo

    Wow. Thank you!, very good!

  73. Author Photo
    Peter van der Does

    Wow, I just made the move to Linode two days ago. I wonder what’s in store with Parts 2 and 3.

  74. Author Photo

    -jaw drop-

    Thnx Linode

  75. Author Photo

    *pats* I loves you linode *squeeze*

  76. Author Photo

    “All you need to do is to reboot to receive this five-fold increase.”

    “In the next few days we’ll tell you about parts 2 and 3 of Linode: NextGen.”

    So, should I wait for parts 2 and 3 for the rest of the goodies to come out before I reboot my node? 🙂

  77. Author Photo

    Good news , but I can not use more than 10% of my transfer 🙂

  78. Author Photo

    so,amazing!!! love all your guys so much!!

  79. Author Photo

    Great work guys!

  80. Author Photo

    You guys are doing great. Great service backed up by awesome updates!

  81. Author Photo

    I’m curious to see what happens after I reboot 🙂

  82. Author Photo

    WOW!!!

    SO F***ING awesome!!!!!

    Great Job!

  83. Author Photo

    Great ! 200 to 2000

  84. Author Photo

    Wow!!! So proud of Cisco Nexus gear. Have you talked to any service providers using it???

    It’s buggy at best. Expect a random change to cause a spanning tree loop, which will take the entire network off line.

    The saying used to be “no one gets fired for buying Cisco”. That was before Nexus. We deployed it and it killed our entire networkore than once. We were wishing we would have gone with something else…Juniper???

  85. Author Photo

    Shit! That’s fantastic!!!

  86. Author Photo

    Staggering upgrade for customers – thanks Chris

  87. Author Photo

    I was contemplating moving to a competitor and using an S3 bucket… not now, great work 🙂

  88. Author Photo

    That is just great news. Keep going!!!

  89. Author Photo

    Just guessing the Part 2 and Part 3… It is going to be RAM, Last RAM upgrades where in 2007 and 2010.. its 2013, so expect RAM to upgraded.. and as Storage was upgraded recently, their wont be much in it.. Additional functionalities and better Load Balancer..

  90. Author Photo

    I just wish I could run FreeBSD on Linode.

  91. Author Photo

    machbio, One of them will have something to do with the ability to have accounts without a linode as mentioned (rather hinted at) earlier. Only thing I can figure is that is a new service beyond the linodes. Otherwise no one would really have a need.

    The other is probably an upgrade to all resources (ram,cpu, and disk).

    Just guessing though

  92. Author Photo

    Linode, this and stability is why your customers are so loyal.

    Fingers crossed for memory upgrades….

  93. Author Photo

    You rock!

    Also, unrelated, would you consider spanning the private networks across datacentres?

    DR for Linodes would be awesome.

  94. Author Photo

    I would love to see memory and increased io/shared disk

  95. Author Photo

    Also, love Linode, they always impress me!

  96. Author Photo

    Awesome!!
    Great Job!!

  97. Author Photo

    Cisco Nexus 7000 routers? I only know Cisco Nexus 7000 series switches. And why chose Nexus? I think products of Juniper is better for High-End networks.

  98. Author Photo

    Thanks. extra memory will be very nice!

  99. Author Photo

    I still don’t see FreeBSD support, so what’s the point?

  100. Author Photo
  101. Author Photo

    Well, THAT’s a nice day-early birthday present. Thanks!

  102. Author Photo

    Pedantic mode: isn’t that a 900% increase, for a new total of 1000% of the original? Either way, pretty awesome!

  103. Author Photo

    Bob, can’t you do FreeBSD using pvgrub?

  104. Author Photo
  105. Author Photo

    WP engine customer saying thanks and thinking it’s been a benefit me to. I have a friend that wants to upgrade shared hosting to something faster I’ve given him some decent alternatives and I’m wondering if anyone has any great ideas for under 20 bucks that somebody used to shared hosting could run?

  106. Author Photo

    Wow.
    I love you, Linode.

  107. Author Photo

    Wow! Very nice of you to do this for us. This reminds me of why I love Linode so much.

    @Shane (3/7)
    Yea… Mine looks nearly as bad.
    http://puu.sh/2eXtV

  108. Author Photo

    I logged in to my manager and my jaw hit the floor when I seen the transfer. Awesome!!

  109. Author Photo

    Linode! Can you please tell me why you are so awesome? Eagerly waiting for the next piece of the cake 😀

  110. Author Photo
  111. Author Photo

    Thanks for the upgrade!!

  112. Author Photo

    Hi,
    Excellent upgrade! I’m looking forward to the next surprises!

    Blake

  113. Author Photo

    This is really great! Thanks for the extraordinary Support Team who are always on top of the Support Tickets.

    Linode always has something to offer every other quarter. Part 1 of NextGen is awesome!

    What will be even more awesome in NextGen Part 2 & 3?
    – Bigger Plans with More Cores/CPUs (today its at 4)?
    – SSD Drives for better IO?
    – More RAM?
    – Built in Firewall?
    – Elastic IP / Global Load Balancer across the DCs?
    – and may be pre-configured MySQL like DBs for HA n Replication

    Would be really great to see Digital Ocean like hardware specs/configurations – specifically CPUs & SSD drives.

  114. Author Photo

    Cool! I wish they also increased the amount of RAM included in each plan 🙂

  115. Author Photo

    Awesome! Love Linode.

  116. Author Photo

    This is great – well done linode!

  117. Author Photo

    I’m running the exact same configuration in my data centers and it’s been very reliable. Just make sure you pick a good code base and have all the EPLD updates done before you go into production.

    I’d be interested in learning what you’re using for a border router.

    Thanks!

  118. Author Photo

    woah! Great! Linode is really always on top of the line. keep it up!

  119. Author Photo

    Gonna be very hard filling up this bar 🙂 http://i.imgur.com/1bazgLG.png

  120. Author Photo

    Solid improvements Linode, very happy with service so far… keep up the good work and you’ve got a customer for life!

    Thanks,
    Paul 🙂

  121. Author Photo

    I guess the next part maybe upgrading the hard drive to hybrid type (HDD+SSD).

  122. Author Photo

    Nice move! Great thanks folks! 🙂

  123. Author Photo

    When part 2 & 3 would come??

  124. Author Photo

    You guys are the BEST! Thanks!!

    i bought 512mb ram plan for one year. using it almost for one month. everything was good until yesterday. starting to saw sudden crashes and server totally stops responding until initiate reboot.

    i was just thinking to move mediatemple vps because they are offering 2x more ram with same price but unfortunately their servers are located only in us.

    also saw the commercials for digitalocean ssd for storage and again looks cheaper but their promises looks very unrealistic to me. i think i should wait and see how serious they are.

    in a nutshell, i would love to see some RAM upgrade and probably bandwith was not the main concern for majority of users.

  126. Author Photo
  127. Author Photo

    I’ll have to second the opinions of many commenters here and say that RAM is probably more of a concern for many of us (including myself!).

    I’m having to spend ‘extras’ each month just so that I can configure a good server, I hope to see RAM increased in the near future to match the competitors.

    In my eyes this is the only think that’s niggling me at the moment with Linode…

    Thanks,
    Paul 🙂

  128. Author Photo

    You are the best! Thank you!

  129. Author Photo

    Out of curiosity, do Linode staff actually read these comments? Paul 🙂

  130. Author Photo
  131. Author Photo

    Crossing my fingers, hoping the next free upgrade involves storage 😀

    Go Linode!

  132. Author Photo

    I never understood the RAM and Storage ‘extras’ from a customer view. It is cheaper to upgrade to a larger Linode. It requires a reboot/resize either way.

  133. Author Photo

    Great work linode! You guys are great!

  134. Author Photo

    Great news ! thanks a lot 🙂

  135. Author Photo

    Linode, this is insanely sick!!!! You just equipped superman with the Iron Man Suit. UNBEATABLE!!!

  136. Author Photo

    I rarely have to log in to linode as the service is soo rock solid I rarely need to.

    However I was actually checking as I am going to change how I use my VPS and feared my Linode will not be able to handle it… I am blown away by your free upgrade (which will indeed handle what I want to do) and all I can say is WOW! Thank you, I get to stay!

  137. Author Photo

    Amazing!!, that´s why I moved all from GoDaddy to Linode…you rock guys!!!

  138. Author Photo

    Linode is the only serious player in the market, you certainly beat everybody else. Thanks!

  139. Author Photo

    Linode Team – Just sending you guys some love – you’re so awesome.

    Thanks for such a great service – you’re an example to others of how to get it right….

  140. Author Photo

    Wow, Made my day. Love it Thank you guys for being awesome 🙂

  141. Author Photo

    @Dash, I looked at the offerings on DO, Ramnode, SSDVPS, lowendbox..

    These folks are running RAID10 on Intel 520 SSDs (consumer grade SSD or equivalent), I don’t think that’s a very good idea, I don’t even run RAID0 on my HDD setup (I run RAID1).

    The prices there are rock bottom but I guess I’ll find out why when an entire host goes down from multiple SSD failures (If I hosted with them I’d be sharing a VPS with write-happy people), and I have to tell my client has been down for 3 days because I can’t get ahold of anybody.

    They also seem like they’re almost fly-by-night, but at least DO seems to be totally domestic and has photos of their peeps.

    SSD for caching I like, such as with ZFS l2arc; but as the main drive, and shared with other people? NOOOOOOOO, just mho
