RAC interconnect switch?
Hi,
We are in the process of migrating from a 10g single instance database to 2 node RAC (Windows Server 2008 OS, EMC storage with 2 SAN swithes,…) and we have some doubts about interconnect.
We are having difficulty in selecting the correct interconnect speed for the interconnect network, difficulty in selecting the switch/switches, …
1. Because there are 2 nodes, and 4 Ethernet cables for interconnect, whether to use one or two switches? Using a switch can be a solution but a single switch become a big single point of failure.
2. Whether we can get in performance if we use 2 switches (bonding,…) ?
3. As mentioned, there are 4 Ethernet cables, is it good idea to use existing 1Gb switches that we use for public network or to buy 1Gb switches that will be used only for private interconnection?
4. Can we use simple 16 or 8 port GigE switches?
Maybe you can point me out to some GigE and SAN switches (for nodes - storage connection) which you've seen that they work without any problems with RAC.
How can we best deisgn the networks for the interconnects?
Thank in advance!
