Abstract: In one aspect, a method includes receiving a first I/O at a kernel interface using a pseudo data storage system, writing the first I/O to a first virtual device on a datastore, receiving a second I/O at the kernel interface using the pseudo data storage system and writing the second I/O to a second virtual device on the datastore.

Abstract translation: 一方面，一种方法包括使用伪数据存储系统在内核接口处接收第一I / O，将第一I / O写入数据存储上的第一虚拟设备，在内核接口处使用第二I / O接收第二I / 伪数据存储系统并将第二I / O写入数据存储上的第二虚拟设备。

Abstract: A system, method, and computer product for enabling a virtual service layer to consume a first storage medium and a second storage medium and map the storage mediums as one or more virtual storage volumes; wherein the one or more virtual volumes are mirrored at a first site and a second site, mirroring of the virtual storage volumes on a distributed mirror, and enabling a distributed replication service to create a continuous data protection image of the data written to one or more virtual storage volumes.

Abstract: A fault tolerance computer implemented method, a computer program product, and a system for allowing asynchronous replication to continue with no lag increase due to RPA failure comprising: creating a consistency group (CG) on a first replication appliance and a shadow copy of the CG on a second replication appliance; sending input/output (IO data), via a splitter, to the CG in a first replication appliance; and sending IO data, via the splitter, to shadow copy of the CG on a second replication appliance.
