Designing Failover Clustering for Windows 2012 and recommendation for shared storage.
Posted on 2014-10-27
I'm planning to migrate our servers to Failover Clustering. I'm still in the stage of studying and researching, but need help to go in detail of this process.
+2 Physical HP Proliant servers, 2X 6 cores, 32GB ram.
+8 Windows server 2012 VMs in total.
+2 SQL 2012 STD (Primary and Backup for daily report generation purpose, Over night Primary SQL backupand restore full database backup to Backup SQL), about 50GB database
+1 Exchange 2010 STD, about 80 mailboxes
+2 File servers, about 100GB data
1. The total disk size needed for this environment is about 200GB giving more space, I say 300GB. I have to evaluate what shared storage is suitable for us. Can you recommend any product to accommodate this environment?
*I have no experience with SAN or ISCSI, but have knowledge by learning, also have tested iSCSI in my Windows Failover clustering using VHD.
2. Between, Servers and the shared storage, do you recommend gigabit or 10gigabit switch? Currently we have Dell Powerconnect 5xxx gigabit switches
3. For SQL and Exchange clustering, Do I set up regular VM clustering or others?
4. What about DC? I should not cluster Domain controllers because they replicate each other already. Is it better to have another physical server or configure one of the two HP Proliant servers as a DC?
5. For SQL, I'm not sure if it's good to run as a VM. SQL is currently installed on a physical host, one of HP Proliant servers.
Thank you in advance.
