Blocked data is normally stored in a data buffer, and read or written a whole block at a time. Blocking reduces the overhead and speeds up the handling of the data stream. [3] For some devices, such as magnetic tape and CKD disk devices, blocking reduces the amount of external
The device mapper is a framework provided by the Linux kernel for mapping physical block devices onto higher-level virtual block devices. It forms the foundation of the logical volume manager (LVM), software RAIDs and dm-crypt disk encryption, and offers additional features such as file system snapshots .
Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...
For example, to minimize downtime, a user can set up server instances in multiple zones that are insulated from each other for most causes of failure such that one backs up the other. Higher-availability database services, like Amazon Relational Database Service run separately from EC2 instances.
