Reliable Cloud host ?
by Randy Carpenter 02 Mar '12

02 Mar '12

Does anyone have any recommendation for a reliable cloud host? We require 1 or 2 very small virtual hosts to host some remote services to serve as backup to our main datacenter. One of these services is a DNS server, so it is important that it is up all the time. We have been using Rackspace Cloud Servers. We just realized that they have absolutely no redundancy or failover after experiencing a outage that lasted more than 6 hours yesterday. I am appalled that they would offer something called "cloud" without having any failover at all. Basic requirements: 1. Full redundancy with instant failover to other hypervisor hosts upon hardware failure (I thought this was a given!) 2. Actual support (with a phone number I can call) 3. reasonable pricing (No, $800/month is not reasonable when I need a tiny 256MB RAM Server with <1GB/mo of data transfers) thanks, -Randy

Riverbed/Akamai/Rakamai
by Kristian Kielhofner 02 Mar '12

02 Mar '12

As long as we're talking about cloud networks, Akamai and Riverbed have finally let out details on their partnership for "optimizing" Cloud applications: http://www.nojitter.com/post/232601716/rakamai-makes-the-cloud-work-better While I'm familiar with Akamai (what they do and how they do it) I don't have any experience with Riverbed. Does anyone know what they actually "do" and how they do it? As usual it's tough to cut through the marketing on the little detail they make available (never a good sign). -- Kristian Kielhofner

02 Mar '12

Hi there, Can someone from AT&T who has any ties to their DSL support contact me off-list? I've been trying to call them all morning but I'm either hung up on or I get forwarded to a voice mailbox that's full. Thanks!

Switch designed for mirroring tap ports
by A. Pishdadi 01 Mar '12

01 Mar '12

Hello All, We are looking for a switch or a device that we can use for mirroring tap ports. For example , take a mirror port off of a core router say a 6509, connect it to a port on said device, say port 1. I would like then to be able to mirror port 1 on said device to multiple ports, like port 2 , 3, 4. We have the need to analyze traffic from one port on multiple devices. Seems most switches are limited to mirroring to a max of 1 or 2 ports. Any suggestions would be great. Thanks, Ameen

Instead of monitoring the physical interface, monitor the vlan from a Cisco IOS perspective on a CAT6500. This will capture all physical interfaces associated with that vlan for mirroring/span.

Hi Ameen, Wouldn't it work to have a switch aggregating your monitor sessions just disable MAC learning? Traffic from a single input interface would be replicated to all other ports on the vlan where learning is disabled. I've used this with a 3750, and I haven't seen any trouble (other than that you don't want that switch in-line with anything else). David Barak

Cisco ME3400
by Holmes,David A 29 Feb '12

29 Feb '12

Anyone with advice on the ME3400 which some telcos use for Metro Ethernet Forum (MEF) services? Specifically looking for layer2 vs layer 3. At Layer 2 NNI/UNI vs dot1q qinq vs private VLANs. At Layer 3 multiple VRF CE/PE support. Specifically which connectivity options have been found to be most reliable and scalable. ________________________________ This communication, together with any attachments or embedded links, is for the sole use of the intended recipient(s) and may contain information that is confidential or legally protected.

Re: [Outages-discussion] Recent outage in Australia affecting Telstra

Perhaps. I am not familiar with Australian jurisprudence, but the US there is the doctrine of Last Clear Chance[1]... and the work necessary on Telstra's part to avoid this problem is a) well known, b) arguably considered best practice for a company in their field, and c) not disproportionately onorous for them to have undertaken... so even if they sue, it's not at all a clear cut case for them to "win".
