I can`t say I`m a big fan of Storage DRS, it seems to me that very small companies that have a limited budget for memory, why bet more E/A on a host, when storage providers (3PAR/IBM, etc.) are already migrating animal in the background, and with scary KB items like kb.vmware.com/kb/2013639 (published on this site) why a production system is threatened, resource aggregation allows multiple memories to be grouped into a single flexible storage space. Administrators can dynamically fill data storage clusters with data storage. Flexibility to separate physics from logic greatly simplifies memory management, as data storage can be added efficiently and dynamically or removed from a data storage cluster to cope with maintenance or space outages. The Load Balancer handles the first placement as well as future migrations on the basis of current workload measures and the use of space. I think it could be D. I had to dig a little for it (for an explanation). www.slideshare.net/VMworld/vmworld-2013-storage-drs-deep-dive-and-best-practices-to-suit-your-storage-environments will contain the SIOC Storage Directive. I would recommend using such a mechanism only if you want to avoid noisy neighbors. The concept is not new, VCD could use these vSAN guidelines for some time and host-based guidelines have already been supported in VCD 10.1.
The only difference is that in 10.2, the customer sets the reservation limited to the VM data support level, but cannot change it. Please note that all memories must be configured with the same storage function. If a data memory is not associated with a storage function or has a different storage function than data memory, the data storage cluster will not display a storage function. A virtual machine – different levels of service required In general, faster hard drives have a higher cost per gigabyte and have a lower maximum capacity per drive, which usually leads to different design and operating decisions. Typically, Tier 1 applications and intermediate data storage mechanisms end up on the fastest storage media pools. Most virtual machines are configured with multiple hard drives. A system support containing the operating system and one or more media containing protocol files and data. The footprint of the virtual machine consists of a working directory and its VMDK files. When checking the requirements of the virtual machine, it is customary that only VMDKs containing log files and databases require low latency discs, while the system disk can be placed in a lower level storage pool.
