Oracle database virtual machine12/1/2023 For each VM, two luns were provisioned from the VSAN datastore. The Oracle Flexible Architecture (OFA) set of naming standards and best practices were used for installing Oracle database 12c software on Red Hat 7.1. Oracle 12c (12.1.0.2) was setup on Red Hat Linux 7.1 and the HammerDB tool was employed for running the benchmark. On each VSAN node we set up a virtual machine running an Oracle 12c database and each of these VMs was configured with 16 CPU cores and 60GB of RAM. Oracle Deployment Layout on Four-Node VSAN Using SanDisk SSDsįigure1: Powering the VSAN Storage layer with SanDisk Solid State Disks (SSD’s) Test Bed Configurationįor our testing purposes, we built a four-node VMware Virtual SAN using Dell Power Edge R730 servers, each with two E5-2690 V3 processors 2.6 GHz, 16 cores per socket, and 256GB of RAM.įor the caching tier, a 400GB SanDisk Lightning Ascend Gen II 12Gb/s SAS SSD was used while the capacity tier was powered by a 1.6TB SanDisk Lightning Eco Gen II 12Gb/s SAS SSD. In this blog I would like to discuss Oracle configuration setup details and testing results on VSAN that will definitely be of interest for DBA’s and IT architects. Insights into VSAN and the role of flash can be obtained from SanDisk® IT Blog virtualization section. If you are not familiar with VSAN, get to know VMware’s solution here. Its architecture pools server-attached storage disks to create a distributed shared data store that abstracts the storage hardware and provides software-defined storage for virtual machines. Data persistence is offered from a cost-effective capacity storage tier to balance the overall cost when deploying an all-flash architecture system. VSAN architecture has a cache storage tier which serves for high-endurance, write-intensive and read-intensive I/O requirements and durability. Having worked with server SAN technology in the form of ScaleIO (now part of EMC), I was excited to have the opportunity to explore the benefits of deploying Oracle 12c on SDS technology, using a four-node VMware all-flash Virtual SAN (VSAN) 6.0. With today’s software-defined storage (SDS) initiatives, we are seeing a rise in the adoption of new server SAN technology, wherein SAN storage functions are migrated to a server stack in order to fulfill these high performance requirements but at a lower cost. The emergence of flash storage in the form of all-flash arrays took center stage for meeting the quick response times and user scalability requirements. But the increase in the number of users accessing database applications, and the associated growth in database size, necessitated new requirements for faster database response time. Previously, traditional storage arrays, built with spinning hard disk drives, were able to manage the performance requirements. Working with Oracle database deployments, from earlier versions such as Oracle 7x to the latest Oracle database 12c, I have witnessed how storage systems have evolved to support Oracle database critical workloads.
