Subject Recommendations for a private cloud
Date Sun, 10 Feb 2013 07:43:26 GMT
Hi All, new to CloudStack and have many questions.  I am looking to
implement a private cloud for our engineering and qa teams to play around
and be able to launch test clusters prior to doing so in the cloud (AWS).
 I started messing around with the CloudStack installation (3.0.2) and
setting up XCP 1.5  and 1.6 hosts and was a bit confused by the networking
setup (this is all internal, the VMs won't have a public interface).  I am
now in the process of starting over.  This time with the incubating release
(4.0.0) and was hoping to use Ubuntu 12.04 + xapi (aka Kronos) as it
provides better support for my network hardware (BCM quad 1Gbe) -- I had to
jump through hoops to get XCP 1.5 to work and 1.6 did not work with CS
3.0.2.

Has anyone had any success with 12.04 + xapi for the nodes?  The script to
add nodes seems to know about Kronos.  If this won't work is there a
preferred Xen host with somewhat up to date drivers (for a Dell R620 with
BCM 5720 Quad)?

Regarding the network setup, what is the recommended setup with 4 1Gbe
ports?  I already have a separate storage network (NFS server has a 10Gbe
link) so I was thinking of bonding 2 ports for storage and 2 for
management/VM traffic.  Does this make sense to bond the second pair?  Do I
need separate subnets for management and vm network or are different ranges
within the same subnet enough (security is not a concern in my deployment).
 Currently, corporate IS is providing me a subnet with DHCP.  Is that going
to be a problem for CS?

I do have the option of adding another dual or quad port card.  If I do,
what would the recommended setup be?  The nodes have 2x8core CPU with 64GB
RAM.

I definitely appreciate any pointers to help me off the ground.

thank you,
Carlos
