SAP & Replication Mgr Architecture design on VMware + SRM + CX4 MirrorView
Hi Community,
I have a customer who is replatforming SAP from Solaris/Sparc to SLES/VMware. This project also includes a DR via SRM. It has been proposed that the data refresh between environments, could be handled by Replication Manager.
During the design phase, we face a problem concerning the replication/mirroring process, as a Clone Target can’t be a mirror source!
Here are the prerequisites:
In case or DR PROD environments (2) need to be restored & running in less than 4h
In case or DR NON-PROD environmentS (8) need to be restored & running in less than 24h
The refresh if the NON-Prod Database with the PROD Data must take less than 4h
The infrastructure will be virtualized on VMware : vSphere 5 and DR will be done with SRM 5
Each environment consists of:
Applications Envir Instance Fonction
SAP/R3 Production SAP PRD DB/ASCS/PAS
SAP/R3 Production SAP PRD AS
ECC/Java Stack Production SAP PRJ DB/ASCS/PAS
ECC/Java Stack Production SAP PRJ AS
BI/Java Stack Production JWP DB/ASCS/PAS
BI Production BWP DB/ASCS/PAS
The replication design is attached.
Does anyone have an idea? Thx,
LouisLu

SRM is not familar for me. Just be curious. Have you ever considered using vPlex?

Hi LouisLu,
Thanks for answering.
Actually it would have been a nice idea, someone else already talked me about RecoverPoint also.
In fact the custommer has already bought the CX4/NS-480 with MirrorView/Fast/FastCache for this usage & the budget doesn't allow extending the hardware
Thx anyway

JeanLouis,
Have you tried to look in the solution section of the Everything_SAP. there is a solution for
Cloning for Virtual SAP Environments with RM and VMware
This solution details the EMC virtual infrastructure for SAP Intelligent Cloning in Virtual Environments enabled by EMC Replication Manager, EMC CLARiiON CX4, and VMware ESX. The solution demonstrates various replication scenarios for an SAP ERP system running on a Microsoft SQL Server database in physical and virtual environments using EMC and VMware technologies. The solution also provides guidelines for designing and building the minimum required infrastructure.
https://community.emc.com/docs/DOC-11358
This could help you. check it out there is a lot of useful information here.

William,
I have some conerns about the projects
1. are we responsible for the SAP migation ? if yes, could you tell us how large the customer database is ? and how much is the downtime?
2. if we only consider the DR site. from my point of view, we could use the recoverpoint to protect their environment.
3. Could you give us the detail requirements ? maybe EMC Solution team can help you to design .

Hi,
Recoverpoint would definitely be THE good idea. But... the customer has already bought the CX4/NS-480 with MirrorView/Fast/FastCache for this usage & the budget doesn't allow extending the hardware
The total DB size is not very large (~300GB) but they have 10 environments that need to be refreshed once in a while (approx 1/month) with PROD data.
I would be glad to receive any help from the Solution team.The project consists of replatforming & virtualizing a ECC6 SAP instance. We are responsible for the virtualization architecture, & coordinating the whole migration.
The Replication Manager option is presented to replace a very long lasting script refresh process used on the Solaris environment.

JeanLouis,
I looked at your attached LUN Replication picture. What surprised me is CG1 in storage 1 is replicated to CG2 in storage 2, then it's replicated back to CG2 in storage 1. These cross-array replications will definitely consume more array resource and SAN bandwidth.Is there a business logic you have to do this?

Hello jingyi,
The refresh of the Pre-Prod environment with the data from the PROD could be done by any of the 2 RM - RDM arrows. I don't mind. Actually my concenr could be a sentence that has been told me by an CX guy:
"the target of a Clone can not be the source of a Mirror" as shown in the MirrorView Knowledgebook

Jean-Louis
Good morning, I have already had a discussion with Tim about your situation. If you are looking for the SDC to help you with your RM design please go to Sales force and open a trouble ticket. Provide us with a description of your problem and we will take it from there. I have done some preliminary research on your RM issue and would like to get your pain points before I continue on.

hi ,
Let me understand your requirement:
1. The project consists of replatforming & virtualizing a ECC6 SAP instance.
2. We are responsible for the virtualization architecture, & coordinating the whole migration
3. 10 SAP system clone from production system
From my point of view, i 'd like to give you some suggesitons
1. Regarding replatforming & virtualization, we should know how much the customer downtime is , as you know the project is SAP heterogenous migration, we should use SAP standard export/import to migrate the system. so the downtime is very important for us and customers. if the customer's SAP includes ABAP+JAVA, we need to pay more attention to JAVA migration.
2. Regarding the virtualization ECC system. the infrastructure design ,you could refer EMC SAP virtualization solutions which provided the best practice for disk and file system layout
3. Regarding the system clone. i think Replication mamanger is the best solution for the system clone which provides the automatical activity for SAP clone and you can do the clone anytime . the detail information, you could refer SAP clone solution.
Thanks!
