Design for Microsoft SQL 2005
in Multi-site Failover Clustering
Situation: We have a register website/PEO (Patron Edge Online) running SQL
2005 on our DMZ. The server has some issues and we are required to re-build
it as high-availability and failover server/website running 24/7.
Design: Our design is based on Microsoft article:
Example Clustered Service or Application in a Multi-Site Failover Cluster:
There are two Dell R510 servers running Windows 64 bit 2008 R2 Enterprise
with Hyper-V enabled. One is located in Building A and another one is in Building B.
2. Each Dell R510 server connects to one EuqalLogic SAN.
3. Each Dell Server has
12 NICs and 48GB RAM.
4. The Clients are in VLAN 1, the Dell R510 servers and
PEO/VM are in VLAN 10/DMZ, the SAN is in VLAN 800.
5. We will use EqualLogic
software to replicate data/VMs between two sites.
6. The PEO will run Windows
2003 R2 Enterprise and Microsoft SQL 2005.
Consideration: We believe we have knowledge to create a Multi-Site Failover
Clustering. However, we donít have experience to use EqualLogic replication
software and experience to build a Multi-Site Failover Clustering. We have
the following questions for you.
Does our Multi-Site Failover Clustering meet the requirement of
high-availability and failover server/website running 24/7? Or is it
2. Do you know if the EqualLogic replication software will work for
this design? Or do we need other 3dr party software?
