Sun has relesed the Sun Storage 7000 series of unified storage systems. The systems use a “hybrid storage pool” consisting of solid state disks, hard disk drives, and RAM to improve performance over traditional HDD-only units.
The Sun Storage 7110 has 8GB of RAM and provides 2TB of storage in a 2U form factor.
The Sun Storage 7210 provides up to 44TB of storage in a 4U form factor.
The Sun Storage 7410 scales up to 576TB with multiple expansion arrays.
In addition, Sun has released a simulator for the units as a VMWare virtual machine image.
