6 Dell Storage PS Series Architecture: Load Balancers | TR1070
2 PS Series overview
Dell PS Series storage is an award-winning, virtualized, scale-out SAN architecture that provides simplified
management, ease of use, a comprehensive set of data protection and recovery tools, and great ROI for both
large and small organizations. PS Series arrays are designed and built to be highly available and work
together to provide virtualized SAN resources called a Group. The inclusive software model means never
having to decipher a complex licensing scheme, and never having to purchase software upgrades to receive
new features. The enhanced Automatic Performance Load Balancer (APLB) introduced in PS Series firmware
version 5.1 is a good example of the outstanding value inherent in the PS Series licensing model: Customers
who have valid support contracts are entitled to download the new firmware, and (once installed on all the
members in the PS Series Group) they can immediately take advantage of its ability to better optimize their
SAN resources — with nothing additional to purchase.
