(57) ABSTRACT A hybrid drive is disclosed comprising a head actuated overa disk
comprising a plurality of data sectors, and a non-volatile semiconductor memory (NVSM) …

BACKGROUND Flash memory differs from many other types of non-vola tile memory in that
it has a limited and predictable lifetime. While a hard disk may experience random location …

Embodiments pertain to live storage migration for virtual machines. Specific embodiments
can implement the migra tion of VM disk images without service interruption to the running …

A method and system of persistent cache invalidation ensures cache durability. A storage
filter driver of a storage input/output (I/O) stack of a server may be used to capture (ie, track) …

(57) ABSTRACT A hybrid storage array one using two or more storage device tiers. In one
implementation, two tiers may be provided by solid state drives (SSDs) and hard disk drives …

An I/O scheduler can manage and schedule write requests that are sent to a storage device
in order to prevent the write requests from dominating a storage buffer of the storage device …

BACKGROUND Hybrid memory generally includes two different memory structures to hold
data. One example includes data storage that uses both volatile and non-volatile memory …

BACKGROUND AS cache memory sizes increase, cache structures tend to be more
vulnerable to soft errors (SER) and detectable unre coverable errors (DUE), due to the …

(57) ABSTRACT A system, including both an OLTP database and awarehouse database,
that is configured to manage the coordination between the OLTP database and the …

Techniques for implementing a hybrid non-volatile memory storage system are disclosed.
The hybrid memory system may include a first non-volatile memory; a second non-volatile …
