Re: [CentOS] Help with IPv6 /48 block

2015-01-10 Thread Mike Mohr
I'm not sure how you plan to manage your /48, but this is how I've seen it done in the past: 1) You are given a single IPv6 address (a /128) for your Internet-facing router. You are expected to add this address to your untrusted interface. You are also given the address of a router at your ISP wh

2015-08-30 Thread Mike Mohr
In my experience the mass market HBAs and RAID cards typically do support only 8 or 16 drives. For the internal variety in a standard rack-mount server you'll usually see either 2 or 4 iPass cables (each of which support 4 drives) connected to the backplane. The marketing material you've referenc

Capturing 10 gigabit traffic with no packet loss at line speed is difficult at best. Make sure that you've configured the IRQ affinity properly on the sending and receiving sides to start. On Aug 14, 2016 11:52 AM, "Gordon Messmer" wrote: > On 08/14/2016 03:20 AM, Anand Buddhdev wrote: > >> The

If your battery backup can handle 2 hours of runtime then it almost certainly has a network management interface. Why aren't you using it to send alerts? On Oct 30, 2016 12:05 AM, "Hadi Motamedi" wrote: > Thank you for your reply. You are correct and the ups is present there but > the battery ch
