Active-active remote configuration of a storage system

A clustered network, comprising:

• a first storage system comprising a first logical volume;
• and
• a second storage system comprising a second logical volume in communication with the first storage system, the clustered network for:
• receiving, at the second storage system, from a host a command to write data to the second logical volume,
• transmitting, by the second storage system, the command to the first storage system,
• writing, by the first storage system, the data to the first logical volume,
• transmitting, by the first storage system, a write permission to the second storage system,
• receiving, by the second storage system, the write permission, and
• writing, by the second storage system, the data to the second logical volume in response to receiving the write permission, wherein:
• the second storage system does not write the data to the second logical volume prior to receiving the write permission, and
• the first storage system writes the data to the first logical volume without permission.

A non-transitory computer-readable medium comprising a computer program product method for storing data in a clustered network comprising a first storage system including a first logical volume and a second storage system including a second logical volume in communication with the first storage system, the non-transitory computer-readable medium comprising:

• computer code for receiving, at the second storage system, from a host a command to write data to the second logical volume;
• computer code for transmitting, by the second storage system, the command to the first storage system;
• computer code for writing, by the first storage system, the data to the first logical volume;
• computer code for transmitting, by the first storage system, a write permission to the second storage system;
• computer code for receiving, by the second storage system, the write permission;
• and
• computer code for writing, by the second storage system, the data to the second logical volume in response to receiving the write permission, wherein:
• the second storage system does not write the data to the second logical volume prior to receiving the write permission, and
• the first storage system writes the data to the first logical volume without permission.
