Understanding the terminology that is used in Smart Scale helps you better understand this feature.
Data Center
A
Data Center is a building, dedicated space within a building, or a group of buildings that contains PowerProtect DD Systems.
The PowerProtect DD administrator can:
Create one or more data centers
Assign a managed PowerProtect DD system to only one data center
Smart Scale Services
Smart Scale Services are deployed from the DDMC into the data center and enable you to create mobile storage units within a system pool.
Smart Scale services provide:
Namespace redirection
Capacity projections and recommendations
Mobile storage unit placement
Capacity and performance analytics
DD Namespace VM
The
DD Namespace VM (DDNVM) is a VM that you deploy from the DDMC into the data center.
DD Namespace Redirection Service
The
DD Namespace Redirection Service (DDNRS) is a service within the DD Namespace VM (DDNVM). DDNVM receives client requests and redirects them to the DD system that is hosting the mobile storage unit.
System Pool
A
System Pool is a defined set of DD systems that you can organize, for example, by workload type (backups for Oracle, VM, and so on). The DDMC manages these DD systems and balances client workloads that access mobile storage units that are hosted on them. A system pool resides in a data center.
Network Groups
Network Groups are objects that describe networks. Each network group corresponds to a set of IP addresses. These IP addresses are configured on DD systems in the data center where the IP address (IP and subnet) and VLAN ID are the same.
Network groups specify the networks that file system clients can use to access a mobile storage unit. A client must connect to a network group IP address that is designated as the pool access IP address for that network group.
Pool Access IP
A
Pool Access IP address is a dedicated IP address that enables client access to the system pool.
Mobile Storage Unit
A
Mobile Storage Unit (MSU) is a DD Boost storage unit that is hosted on one of the DD systems in a system pool.
DD Boost clients access the mobile storage unit through its specified networks.
Mobile Boost User
A
Mobile Boost User is a DD Boost user that is assigned to a mobile storage unit.
Clients that access a mobile storage unit must provide the username and password of its mobile DD Boost user.
