VMWare Storage Growth – 5 Best Practices for Capacity Planning
Virtualized system resources often consume more storage than expected due to the proliferation and ease with which virtual machines (VMs) can be created. When using shared storage that supports VMWare or Microsoft Hyper-V (the two leading virtualization technologies), you can expect two waves of increases. The first will occur at the onset of the virtualization effort. The second wave will happen as users gain acceptance—and test, development and quality assurance copies are created to build new unique environments and feature sets.
Here are five tips for making sure your VMWare storage can handle those increases:
1.Use faster storage to avoid performance bottlenecks, such as fibre channel or SAS drives. SATA can get you in trouble long-term on larger VMWare platforms as the low RPM speeds can adversely affect performance.
2.Plan for lots of growth. You will likely need 2x-5x more than you initially thought as users begin utlilize virtualization for test, development, and copies.
3.Buy or upgrade your system with lots of capacity to spare. If you need 20TB of VMWare capacity, buy a system that has 40-80TB of available space.
4.Don’t overcrowd or consolidate too many performance-rich applications on a single mid-range array. Copies of Oracle, I/O Intensive Backup Applications, SQL, VMWare, Files, and Exchange should are likely offenders if you’re experience disk contention.
5.Budget carefully. When planning for VMWare storage, you want to make sure to include primary storage, replication storage, backup storage, impact on local backups, SAN infrastructure and backup licensing, to name a few.
Finally, since VMWare can quickly become a “crown jewel” that requires a high degree of protection, plan for disaster recovery. Keep in mind that several software replication tools are ideal for VMWare replication, so you don’t have to rely on the storage replication if you don’t want to.
