Regardless of the underlying technology solution, as anything becomes increasingly popular and widespread in use, certain pieces of sometimes inaccurate information about that product become permanent fact, often taking on legend-like status. Moreover, as a product matures, it changes; it evolves by taking on new features, shedding old ones and improving the functionality everywhere else. However, no matter how much a product matures and no matter how much it evolves, many products carry with them myths that follow through the ages. Myths that may or may not have once been true, but are used as truisms nonetheless even as the version count rises ever higher. In this white paper, we will expose four such myths.- Myth #1: RDMs have better performance than VMFS
- Myth #2: Changed Block Tracking causes significant overhead on your virtual machines
- Myth #3: Resource pools should always be used to categorize and allocate resources to virtual machines
- Myth #4: LSI Logic SCSI is always better than paravirtualized SCSI
