Mission-critical applications are mission critical because, without them, business operations will cease or fail. The apprehension with virtualizing mission-critical applications has always been performance, since server consolidation means multiple workloads will share server resources. The good news is that today’s CPUs offer the compute power to handle critical workloads. More recently, most of the worry has been about IO. Can the infrastructure handle IO-intensive workloads like Microsoft SQL Server, Microsoft Exchange, Oracle, and others?
SimpliVity’s data efficiency is the keystone to our hyperconverged infrastructure’s ability to deliver improved performance. Many of our customers tell us that running applications on SimpliVity hyperconverged infrastructure actually improves performance.
SimpliVity recently published its Reference Architecture for Microsoft Exchange—and we have more coming soon for Microsoft SQL Server and Oracle. This is a great effort to demonstrate the efficiency and performance gains that SimpliVity’s TRUE hyperconverged infrastructure provides its customers for their most mission-critical applications. Efficiency and performance are two compelling reasons our customers cite as benefits of running SimpliVity hyperconverged infrastructure. In fact, according to results from a third-party survey by TechValidate, 52% of SimpliVity’s customers surveyed run Microsoft Exchange, 25% run Oracle and an amazing 80% run SQL Server on our hyperconverged infrastructure.
Some of our prospective customers are under the impression that “Microsoft doesn’t support NFS” and “Oracle doesn’t run on VMware.” Well, we’d like to put some of those misnomers to rest.
With regards to Microsoft Exchange and SQL Server, Microsoft published a requirements document for underlying infrastructure, including a requirement for “write ordering,” stating:
- “A tenant of the WAL [Write-Ahead Logging, which is a required protocol by SQL Server to maintain Atomicity, Consistency, Isolation and Durability (ACID)] is write ordering or order preservation. An SQL Server solution must provide write ordering capabilities.”
This is one of the biggest concerns with Microsoft Exchange or SQL Server running on NFS. However, VMware released a Knowledge Base (KB) article, updated as recently as November 2014, where VMware states:
- “Write ordering and write-through integrity for NFS storage are both satisfied with NFS in an VMware ESX/ESXi environment.”
The second major application where customers voice concern is Oracle. Oracle’s support of VMware, or lack thereof, has been an ongoing debate for a decade. The objections we typically hear are:
- “Oracle won’t support an Oracle application on VMware.”
- “Oracle will force me to replicate my problem in a physical environment first before it will support an Oracle application running on VMware.”
This belief is no longer true as Oracle has changed its stance on VMware, as reflected in VMware’s updated support policy (By the way, SimpliVity is a member of the Oracle Partner Network [OPN]).
SimpliVity supports its customers’ mission-critical applications. If an application runs in a virtual machine, it will run on SimpliVity hyperconverged infrastructure.
