Aha...I think SBS might be a problem! SBS does NOT support 2 NICs, that's your problem. Sorry I missed that in your other post.<br />
<br />
Instead, configure 2 IP subnets on single NIC adapter, put iSCSI Drobo in 10.0.0.x range and the rest of the network will not see it by default. It's kinda lousy security, but better than nothing.

This has always confused me. I believe that I have had more than one NIC working in SBS 2008 and this has thrown me in 2011.<br />

&quot;Lousy security&quot; - what would you recommend in this configuration.

<div class="content wysiwyg-content">
We are running SBS 2011 Server, patched and up-to-date.<br />
The server have five NICs board.<br />
<br />
The internal network is running on 192.168.1.X<br />
We have a iSCSI Drobo that is used for backups.<br />
Ideally I'd like to have it on a different range so that is not visible from the rest of the network.<br />
<br />
But if I put it on 10.0.0.Y the network starts to slow down and I have to disable the iSCSI NIC, whence it regains speed.<br />
<br />
Can anyone point me towards best practice and how to successfully install such a device?

Small Business Server (SBS) is a line of server operating systems targeted at small businesses by bundling the operating system with a number of other Microsoft products that would normally need to be purchased or licensed separately. The most notable inclusions are Exchange, SQL Server, SharePoint and ISA/TMG (Microsoft's firewall and proxy server).

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.
