Subject: [Users] help me validate my design

I like to give a brief description of what I'm taking to production he= =3D re in a couple weeks, and I like some opinions if this is a valid design, a= =3D s well as id love to hear some anecdotal evidence of similar deployments as= =3D well.

My nodes will be 8 dell M620s with 96GB ram and dual 10core intel proc= =3D essors. As they are in M1000 chassis, I will be using fabric A for ov= =3D irtmgmt network and the fabA interfaces will be a bond mode1. Fabric = =3D A is a pair of cisco 3130s, and the stacking cables were not used by previous admin and are long lost (thus, the mode1 = =3D for ovirtmgmt). The fabric B will be dual port broadcom mezzanine car= =3D ds into powerconnect 6348s that will be stacked. My fabB will be used= =3D for iscsi traffic that will be on a equalogic iscsi SAN, and node interfaces will be a mode4.

Regular network traffic for both nodes and Vm's will go thru ovirtmgmt= =3D , and iscsi traffic will be isolated on the dedicated 6348 switches. = =3D Some Vms will have interfaces for iscsi, as they will have their own dedica= =3D ted luns on the EQ SAN for their own data.

Am in on a valid track here?

Thanks for your opinions,

jonathan

Hi Jomathan,
I think it'll be easier to relate to specific performance areas, which usua= =3D lly come up later in the process.

Try organizing your setup based on the following areas;

1. Network design
- What connect where, which networks will you have?
- Capacity planning
- Special considerations (VLANs, etc).

2. Storage design
- What connect where, and how: iscsi, nfs, FC, etc.
- Capacity planning

3. Management server
- Fedora?
- CPU
- RAM
- Networking
- Will it include other Apps?

4. Hosts
- Fedora or ovirt-nodes?
- CPU
- RAM
- Networking
- Capacity plan
- Fencing?

Based on the above it'll be easier to see if we can expect issues.
