PureSystems is an IBM product line of factory pre-configured components and servers also being referred to as an "Expert Integrated System".[1] The centrepiece of PureSystems is the IBM Flex System Manager in tandem with the so-called "Patterns of Expertise" for the automated configuration and management of PureSystems.
PureSystems can host four different operating systems (AIX, IBM i, Linux, Windows) and five hypervisors (Hyper-V, KVM, PowerVM, VMware, Xen)[2] on two different instruction set architectures: Power ISA and x86. PureSystems is marketed as a converged system, which packages multiple information technology components into a single product.
Architecture
The architecture itself is called IBM Flex System.[3]
It aims at managing hybrid cloud infrastructure environments "out of the box".
The basic intention is for the combination of integrated hardware and software that can be easily maintained. A similar concept had already been introduced with the IBM AS/400. Today, such systems are called converged systems. More specialized integrated hardware and software are referred to as appliances.
The compute nodes of the server blades can be x86 or Power ISA and they can be used either individually or mixed in the same rack simultaneously, thus offering a hybrid ensemble which borrows from the zEnterprise/zBX ensemble[4][5] (cf. a gameframe), including its ability to manage a combined physical/virtual hybrid environment from a single console.
PureSystems is shipped with the IBM Flex System Manager.[6] It is an appliance which manages the resources according to the so-called "Patterns of Expertise", which provide field engineers' expertise from decades of system configuration. These "Patterns of Expertise" offer industry-specific (e.g. banking, insurance, automotive) defaults for the fully automatic and optimal orchestration of resources (e.g. workload balancing). PureApplication uses in conjunction with the IBM System Manager first Flex repeatable software patterns (pattern) and industry-specific processes, which are derived from the year-long collaboration of IBM with their customers and business partners.[7]
Platform
The basic building block of the system is the 10U high Flex Enterprise system chassis with 14 bays in the front for compute nodes ("servers") and storage nodes. Additionally, there are bays in the rear for I/O modules.
A flex-chassis can accommodate up to 14 horizontal compute and storage nodes in the front, and 4 vertically oriented switch modules in the rear. Contrasting to this, the IBM BladeCenter (9U high) has vertically oriented compute nodes ("blades"). This means that the components between the BladeCenter chassis and Flex chassis are not interchangeable.
Based upon the Flex Systems architecture (the components of which are individually available), there are three main products:
- PureFlex System (IaaS)
- PureApplication System (PaaS)
- PureData System (tightly coupled and specialized computer appliance / software appliance)
