SAN Network Solutions

Jump to solution

Data center networking has always been a gray area for me, but I always want to learn it. I have spent sometime reading documents about MAN & WAN, and now I would like to have your expertise in it. I understand SAN Network Solutions are purely based on the application latency tolerance level, your infrastructure, distance between sites and transport medium available between sites, but I am focusing mainly on widely used methods.

Objectives:


1. Remote Replication

2. SAN extension

Methods available:

1. SAN over fiber - Direct connections between two SAN switches. Distance is limited to 10km - Long wave lasers GBICs. FC protocol.

                SAN switch <-Fiber-> SAN switch

2. SAN over DWDM over fiber - SAN switch/GigE connectors will be connected to DWDM Multiplexer - Supported FC and GigE protocols [Diff wavelengths]. These wavelengths are then multiplexed in single light bundle, which can be transported on a single fiber pair. DWDM cannot be used in WAN - i.e., more than 200KMs. Is that correct?

SAN switch/GigE Connector - DWDM MUX <-Fiber-> DWDM MUX - SAN switch/GigE Connector

3. SAN over IP over GigE over Fibre - Can we call this as a FCIP tunneling?

SAN switch - IPSAN GW switch - GigE Switch <-Fiber-> GigE Switch - IPSAN GW switch - SAN switch

4. SAN over GigE over Fiber - 10GigE - Optical media only - Only Fibre. 10GigE does not support copper. Is that correct?


           SAN over GigE - GigE Switch <-Fiber-> GigE Switch - SAN switch


5. Is anyone using WAN IP?

6. Widely used methods in WAN?

Hi,

Suggest to get in touch with your local EMC team, to get detailed answers on your questions, unless somebody here on the Forum is willing to explain in detail.

Regards,

Ed
