Are VMWARE hypervisors able to cap or throttle a VM's consumption of shared disk subsystem resources on a multi-tenant server? Or is there always the possibility that another VM on the server, a VM hosting some other tenant's database engine, will have a runaway query or a query against tables with poorly defined or fragmented indexes, or just heavy peak usage at certain times of day or on certain days of the month, any of which could hog the disk subsystem and result in transient-faults for the other tenants?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
