PureSystems is an IBMproduct line of factory pre-configured components and servers also being referred to as an "Expert Integrated System". 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 and five hypervisors 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. 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, including its ability to manage a combined physical/virtual hybrid environment from a single console. PureSystems is shipped with the IBM Flex System Manager. 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 defaults for the fully automatic and optimal orchestration of resources. PureApplication uses in conjunction with the IBM System Manager first Flex repeatable software patterns and industry-specific processes, which are derived from the year-long collaboration of IBM with their customers and business partners.
Hardware
The basic building block of the system is the 10U high Flex Enterprise system chassis with 14 bays in the front for compute nodes 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 has vertically oriented compute nodes. This means that the components between the BladeCenter chassis and Flex chassis are not interchangeable. Based upon the Flex Systems architecture, there are three main products:
PureFlex System
PureApplication System
PureData System
PureFlex
PureFlex is a factory pre-configured and combined hardware-/software system for IaaS in terms of cloud computing. It combines server, network and storage. IBM PureFlex is available in three configurations: Express, Standard, Enterprise.
PureApplication
PureApplication is a pre-configured platform for platform as a service applications. It is optimized for transaction-oriented web and database applications. PureApplication comes with IBM DB2 database and WebSphere Application Server pre-configured so users can run their applications into a preconfigured middleware engine. Unlike PureFlex, which is sold by IBM Systems and Technology Group, PureApplication is marketed by the IBM Software Group. IBM claims that PureApplication allows for installation of new applications within four hours. The system's virtual pattern deployers encrypt on-disk data using Security First Corp's SPxBitFiler-IPS encryption technology, which is also licensed by IBM for its Cloud Data Encryption Service. IBM PureApplication System is available in three classes:
W1500-32 and W1500-64, using Intel Xeon E5-2670 processors, housed in a 25U rack
W1500-96 through to W1500-608, using Intel Xeon E5-2670 processors, housed in a 42U rack
W1700-96 through to W1700-608, using IBM POWER7+ processors, housed in a 42U rack
Both IBM and its partners provide software which is specifically certified for PureSystems. Currently, over 125 ISVs have already certified products for PureSystems, and business partners such as system integrators, resellers, distributors, ISVs or MSP can integrate PureSystems into their portfolio.
