56 businesses that need shared storage but do not need all the features of an enterprise storage solu- tion, a solution such as VMware Virtual SAN™ can save capital expenses and ongoing management costs. Sizing and Managing Shared Storage Virtualization allows you to pool your storage infrastruc- ture, which gives you flexibility for optimal workload placement. You can place highly volatile I/O workloads such as Tier 1, mission-critical database applications on Tier 1 backend storage, such as high-speed SSDs or enterprise-grade SAS disks. At the same time, you can move test and development environments or rarely accessed data to slower and lower-cost storage to reduce expenses over the long run. When sizing and managing your shared storage, you should: ✓ Monitor how much space is used on your existing physical volumes, and also the number of IOPS (I/ Os per second) your workloads use. This informa- tion can help you choose the right type and size of disks for your new environment. ✓ Calculate your storage needs, in both raw capac- ity and IOPS, on current and future workloads. What's the best way to meet those needs? Do you need the array-based replication or extreme amounts of capacity that a traditional storage array can provide? Or could your needs be met by a more cost-effective Virtual SAN solution that allows you to scale storage capacity and perfor- mance as you add physical host servers?
