Backup and restore: With the ability to mirror data between
storage systems over IP and/or Fibre Channel host ports,
the DS3500 Express can support short backup windows and
recovery times for high productivity.
Storage solution: The DS3500 Express offers enhanced
Tivoli Storage FlashCopy services, thin provisioning and
advanced software features for small and mid-size businesses.
Data protection: The DS3500 Express offers simplified
provisioning, improved rebuild times and more consistent
performance under failure via selectable disk pooling.
Campus area replication: When replicating data across a
high-speed Fibre Channel SAN or IP networks, data can be
mirrored synchronously, ensuring that remote sites have the
exact same data as the local site at all times.
