VMWare Storage Growth – 5 Finest Practices for Capacity Planning
Virtualized method resources usually consume more storage than expected because of the proliferation and ease with which virtual machines (VMs) could be designed. When utilizing shared storage that supports VMWare or Microsoft Hyper-V (the two leading virtualization technologies), you are able to anticipate two waves of increases. The first will occur at the onset of the virtualization effort. The second wave will happen as users acquire acceptance-and test, development and quality assurance copies are created to build new distinctive environments and feature sets.
Here are 5 guidelines for making sure your VMWare storage can handle those increases:
1. Use faster storage to stay away from performance bottlenecks, like fibre channel or SAS drives. SATA can get you in trouble long-term on larger VMWare platforms as the low RPM speeds can adversely impact efficiency.
2. Plan for a lot of growth. You are going to most likely require 2x-5x more than you initially thought as users start to utlilize virtualization for test, development, and copies.
3. Acquire or upgrade your method with plenty of capacity to spare. Should you need 20TB of VMWare capacity, purchase a system that has 40-80TB of obtainable space.
4. Do not overcrowd or consolidate too numerous performance-rich applications on a single mid-range array. Copies of Oracle, I/O Intensive Backup Applications, SQL, VMWare, Files, and Exchange need to are likely offenders if you’re encounter disk contention.
5. Spending budget carefully. When planning for VMWare storage, you want to be sure to contain main storage, replication storage, backup storage, impact on local backups, SAN infrastructure and backup licensing, to name some.
Finally, since VMWare can quickly grow to be a “crown jewel” that demands a high degree of protection, plan for disaster recovery. Maintain in mind that numerous software program replication tools are perfect for VMWare replication, so you do not need to rely on the storage replication if you do not wish to.
