CenturyLink Transforms SAP Deployment Model with VMware Virtualization

CenturyLink SAP

We recently worked with CenturyLink, one of the largest telecommunications companies in the United States, to optimize their virtual SAP HANA solutions. The outcome is below referenced success story, where CenturyLink describes how they use the VMware platform, to provide a customized private cloud for SAP applications, including SAP HANA in less than 28 days, with no compromise on performance.

A SAP infrastructure project duration of 28 days may not sound so fast, but remember, this is a for a completely customized SAP private cloud solution and not just some standard, simple SAP HANA instances running somewhere in the public cloud, as a test or development system. Regarding CenturyLink, customers can deploy new SAP workloads up to four times faster, compared to in-house implementations, where these deployments typically take over 100 days!

Deploying a complete SAP landscape includes several systems like SAP Solution Manger, SAP Gateways, load balancers, several applications servers and finally the SAP HANA database. All these systems need to get configured, patched up to the latest software release level and connected by maintaining highest security standards. All this will get done, if wished, by CenturyLink.

Beside faster time to market, CenturyLink can utilize templates and repeatable processes, which helps it easily standardize and scale its offering while managing costs, complexity, and risks. This all leads to CapEx savings of up to 60 percent and OpEx savings in a similar range for CenturyLink customers. For instance, as an SAP HEC partner, CenturyLink had to deploy without SAP HANA VMware vSphere virtualization, 20 physical server systems to support 20 independent SAP HANA systems in the past. Now they deploy a VMware cluster of 8 hosts to support these 20 SAP HANA instances, including HA, which is a HW reduction by 12 hosts or 60 percent. 60 percent less power and cooling costs, rack space savings and reduced HW maintenance costs are only the more comprehensible cost savings realized. Additionally, to this the easier operation of a virtual, software defined environment, are major, long-term, cost saving factors.

These are the reasons why CenturyLink wants to go one step further towards a fully software defined data-center and plans to implement a VMware Virtual SAN™ based hyper-converged infrastructure ready to run even the more demanding SAP workloads.

To be “RDM for Oracle RAC”, or not to be, that is the question

Famous words from William Shakespeare’s play Hamlet. Act III, Scene I.

This is true even in the Virtualization world for Oracle Business Critical Applications where one wonders which way to go when it comes to provisioning shared disks for Oracle RAC disks, Raw Device Mappings (RDM) or VMDK ?

Much has been written and discussed about RDM and VMDK and this post will focus on the Oracle RAC shared disks use case.

Some common questions I get talking to our customer who are embarking on the virtualization journey for Oracle on vSphere are

  • What is the recommended approach when it comes to provisioning storage for Oracle RAC or Oracle Single instance? Is it VMDK or RDM?
  • What is the use case for each approach?
  • How do I provision shared RDM (s)  in Physical or Virtual Compatibility mode for an Oracle RAC environment?
  • If I use shared RDM (s)  (Physical or Virtual) will I be able to vMotion my RAC VM ’s without any cluster node eviction?
