Hi Frank If the storage network is for Secondary Storage, why does the admin guide contain the following
"For the separate storage network to work correctly, it must be the only interface that can ping the primary storage device's IP address. For example, if eth0 is the management network NIC, ping -I eth0 <primary storage device IP> must fail. In all deployments, secondary storage devices must be pingable from the management network NIC or bond. If a secondary storage device has been placed on the storage network, it must also be pingable via the storage network NIC or bond on the hosts as well." And it also states "The secondary storage NFS export is mounted by the secondary storage VM. Secondary storage traffic goes over the management traffic network, even if there is a separate storage network. Primary storage traffic goes over the storage network, if available. If you choose to place secondary storage NFS servers on the storage network, you must make sure there is a route from the management traffic network to the storage network." This seems to make it very clear that the "Storage Network" is for Primary Storage, not Secondary.

The storage network(I admit it's a bad term for this feature) is indeed for secondary storage now. > -----Original Message----- > From: Weiran Xia [mailto:weiran.x...@gmail.com] > Sent: Friday, June 22, 2012 4:57 AM > To: cloudstack-dev@incubator.apache.org > Subject: Re: Storage Networks XenServer > > here i got a similar question, there seems be some confusion in terminology. > > From > http://wiki.cloudstack.org/display/DesignDocs/Storage+network+in+Acton > it says a storage network is for speeding up template/snapshot copying > process, and indeed during the zone creation process there is a step > of configuring this network(ip range,gateway..). when the SSVM is up > and running it gets 4 NICs, one of them is dedicated for this purpose. > > But where is the storage network for primary storage? is this storage > network only defined by label in step two (drag and drop) of zone creation? > is there any relationship between two 'storage networks'? > > thanks very much if someone can clarify the storage nework in 3.0.x > > Regards > Mice ShapeBlue provides a range of strategic and technical consulting and implementation services to help IT Service Providers and Enterprises to build a true IaaS compute cloud.
