White Paper: Continuous Server Availability with VMware and NetApp White Paper

The white paper described provide the ability to maintain HA for both the computing and storage resources between the sites and the ability for complete disaster recovery in the event of the loss of a whole site, as well as the ability to move the complete operation of the environment between the two sites to minimize disruption during scheduled downtime events.

A Virtual Infrastructure is the Foundation for a Dynamic and Cost Effective Disaster Recovery Solution

 

If possible, all organizations would elect to have both a disaster recovery plan and solution in place. While many organizations have adisaster recovery plan, the cost of implementing a disaster recovery solution is typically the main challenge preventing such a solution from becoming a reality.

A virtual infrastructure in both the primary and recovery sites not only reduces the costs associated with implementing a disaster recovery solution, it may also improve business continuance by providing high availability of services within the primary data center.

When a service fails, the recovery process should be as efficient and simplified as possible. A virtual infrastructure provides options to automate both local and geographic service recovery. While VMware vSphere 4 incorporates local high availability solutionsVMware vCenter Site Recovery Manager may provide that "easy button" during a geographic recovery scenario and a method to test and validate current failover plans while integrating additional tasks required during a recovery situation.

Engaging Agile360 can help you ensure the best of breed choices, intelligent and efficient technologies, ease of use, quality and reliability for mission critical virtualization environments.

Define "Service Paths" to Deliver a Robust IT Infrastructure

How many times have you heard someone say "That’s the most important server in the environment"? Although this may be true from the perspective that the server runs the most critical business application, what about everything else it requires to deliver that application?  What about the web page or XenApp interface that users depend on to access the application?  What about the back-end database or file server that stores all of that critical data?  What about the domain controller used to authenticate users to the application? Can you deliver a highly available service without knowing what the weakest link in the chain is? It’s important to view all of these critical elements as a single service path rather than an application, server or device. The definition of the service paths is usually the first step in any disaster recovery initiative.

Let’s go through a very simple example now. First you need to define the service that is being offered.

Service:
 Corporate E-mail

Then you need to define the critical components that make up that service.

Critical Components: Microsoft Exchange, Shared Storage, Active Directory, DNS, Outlook Web Access, Email Archive server, SQL 2005 (archive database)

Lastly, identify the Servers/Devices that run those components.

Servers/Devices: Exch01 & Exch02 (Cluster), NetApp FAS3020, DC01-DC10, OWA01, Nearpoint01, SQL02

Once the service paths of an IT environment have been defined then these services can be assigned specific recovery point objectives (RPO) and recovery time objectives (RTO).  Finally, the technical solution or solutions can be identified and evaluated to meet those objectives.

Tech Corner: Citrix NetScaler - Delivering High Availability and Global Server Load Balancing


image014.jpgCitrix has been delivering Windows based applications and desktops since its inception in 1989. When Citrix acquired NetScaler in 2005, it allowed Citrix to enter the Web Application Acceleration and Delivery market. Since the acquisition, Citrix has been developing integration with its existing product line and its future roadmaps. One major benefit in Citrix NetScaler is the ability to provide High Availability (AKA Load Balancing) and Global Server Load Balancing (AKA GSLB) for site to site recovery of mission critical applications. By providing intelligent load balancing to monitor high availability of servers and services, Citrix NetScalers can provide redundancy within the same datacenter. Then leveraging the same monitors, the Citrix NetScalers can extend this capability to provide site to site protection of applications via GSLB. 

If you are trying to deliver a highly available or disaster plan forMicrosoft SharepointMicrosoft Outlook Web AccessIBM WebSphereSAP Business Suite , Oracle’s PeopleSoft Enterprise, or any other Web Based application, than this is the way to go.

And if you have Citrix XenApp or XenDesktop, then you need to read how Citrix NetScaler can make your Citrix XenApp and/or XenDesktop environment highly available and prepared for disaster recovery.

Tech Corner: Utilizing Double-Take to Provide Near Zero Data Loss for Systems with Rapidly Changing Data


dt2.JPGTo identify a proper solution to protect business critical services, it is vital to start with the identification of each service’s recovery requirements. These include areas such as the Recovery Time Objective (RTO, how quickly a service needs to be recovered), the Recovery Point Objective (RPO, acceptable level of data loss), local or geographic recovery and other important requirements. It is important to realize that not all recovery solutions provide suitable protection for systems with rapidly changing data. Many solutions provide point in time recovery with data loss in the range of hours to days.

When near zero data loss is required, solutions such as Double-Take Availability can provide the appropriate protection for key business services such as Microsoft Exchange, SQL, SharePoint, Blackberry Enterprise Server and more.

Double-Take solutions not only provide a means to failover to a recovery environment (local or remote), but also the commonly overlooked task of transitioning back from the recovery environment once the primary environment has been restored.
