Abstract: In one aspect, a method includes replicating a first volume of a first storage array to a second volume of a second storage array and notifying a first splitter of a start of migration. The first splitter is configured to send I/Os sent from an application to the first volume to a first data replication appliance (DPA) to be replicated at the second volume and configured to send the I/Os to the first volume. The method also includes configuring a second splitter of a third storage array to: ignore data migrating from the first volume to the third volume and send the I/Os sent from the application to the third volume to the first DPA to be replicated at the second volume and to send the I/Os to the third volume; and migrating data from the first volume to the third volume.
Abstract translation: 一方面，一种方法包括将第一存储阵列的第一卷复制到第二存储阵列的第二卷并通知第一分离器开始迁移。 第一个分离器被配置为将从应用程序发送到第一个卷的I / O发送到要在第二个卷上复制的第一个数据复制设备（DPA），并将其配置为将I / O发送到第一个卷。 该方法还包括配置第三存储阵列的第二分离器以：忽略从第一卷迁移到第三卷的数据，并将从应用发送到第三卷的I / O发送到第二DPA以在第二卷被复制 并将I / O发送到第三卷; 并将数据从第一卷迁移到第三卷。

Abstract: In one aspect, a method to provide asymmetric active-active access to a first storage volume using a global cache coupled to a first and second virtual storage volumes includes replicating asynchronously the first storage volume at a first site to a second storage volume at a second site, virtualizing the first storage volume with the first virtual storage volume; and virtualizing the second storage volume with the second virtual storage volume. The first storage volume has primary storage functionality.
