Mimosa Systems offers tiered storage option

Live content archiving provider, Mimosa Systems Inc. reports that by adding a Tiered Storage Option module to an existing NearPoint platform, IT administrations and legal stakeholders are given the power of intelligent provisioning of content to multiple tiers of storage within the archive. This thereby speeds up the e-discovery review process by staging potentially responsive data on a high-speed disk, making content accessible to legal review staff.
