Comment on One Year Later: Questioning Cisco UCS by Joesilver

Have you ever had your whole data center crash? Well, I’ve seen it twice now, all on UCS. The DME in UCS makes it great, save configurations, blah, blah, but it is also its Achilles heel. If you get bitten by bad “firmware”, the result of a power hit to your UCS, you better pray you have the “good” firmware in place, otherwise, the blades do not come up as advertised. Also, are you tight on space in your co-lo? only have power for 3 UCS chassis in a single rack? Well, you can power up two HP C-7000′s with the same power. Difference? 3 * 8 24 UCS blades or 2 *16 or 32 HP blades. I think I will take the extra blades and horse power.

Amazing, business data deduplication is a mission! I need all the help I can get.

Someone .

we have 400 ( ok “had” ) physical 1U,2U and 5U Ibm boxes in 20 racks with associated cabling and ports on 5Ks and fexes and top of rack switches.

Now we have 2 UCS 6100 clusters with 2 chassis each and 10 blades per cluster ( room to grow ).
It takes up the top half of 2 racks, no 5K ports and probably will pay for itself in electricity savings alone in under 2 years.

yea .. marketing hype ….we’ll never buy another physical server again. … And I go back to a Z80 proc running CP/M.

Comment on Coping Mechanisms For A Lying ARP Cache by Kez1985

I appear to have a problem which I think is related to this issue and unfortunately have not come across any forums describing the issue at hand. I have a number of hosts on a reasonably small single switch network, the switch I am using is a cheap Linksys 1214 48. I have separated all hosts into a different vlan with a separate subnet for each and a Linux server(iptables) acting as router between them and the internet/other misc network devices. The other day I changed my mac address to test some firewall functionality and since then I have not been able to connect via any protocol to the other linux servers on the network. I am able to ping the Linux router but I cannot connect via ssh. When attempting to connect via ssh I receive this tcpdump:

20:31:35.715360 ARP, Reply 10.64.118.11 is-at 00:24:7e:6f:be:ee (oui Unknown), length 28

Both the server and my host are Linux based and I have attempted a power cycle on all switches on the network, my host and the Linux router. Nothing has helped.

Comment on vSphere 5–PXE Installation Using vCenter Virtual Appliance by Gsr Kashyap

I think at 6th step it should be kernel /esxi50/mboot.c32 instead of mboot.cfg

“Using the following picture as reference, add “/esxi50” to the paths for ‘kernel’ and ‘modules’”Instead of modifying all the locations manually just add a line
prefix=/esxi50/
that will save some typing!
