IBM Real Time Compression with IBM XIV Storage System Model 314
Disk storage

Redpaper, published 16 Feb 2016, last updated 22 Feb 2017

IBM® Real-time Compression™ is fully integrated in the IBM XIV® Storage System Gen3. Real-time Compression provides the possibility to store 2 - 5 times more data per XIV system, without additional hardware. This technology also expands the storage-replication-related bandwidth, and can significantly decrease the Total Cost of Ownership (TCO). Using compression for replication and for volume migration with IBM Hyper-Scale Mobility is faster and requires less bandwidth for the interlink connections between the XIV storage systems, because the data that is transferred through these links is ...

A Deployment Guide for IBM Spectrum Scale Unified File and Object Storage
Cloud

Redpaper, published 14 Feb 2017, last updated 20 Feb 2017

Because of the explosion of unstructured data that is generated by individuals and organizations, a new storage paradigm that is called object storage has been developed. Object storage stores data in a flat namespace that scales to trillions of objects. The design of object storage also simplifies how users access data, supporting new types of applications and allowing users to access data by using various methods, including mobile devices and web applications. Data distribution and management are also simplified, allowing greater collaboration across the globe. OpenStack Swift ... [more]

Benefits of Configuring More Memory in the IBM z/OS Software Stack
z Systems

Redpaper, published 21 Jan 2017, last updated 18 Feb 2017

Significant performance benefits can be realized by increasing the amount of memory that is assigned to various functions in the IBM® z/OS® software stack, operating system, and middleware products. IBM DB2® and IBM MQ buffer pools, dump services, and large page usage are just a few of the functions whose ease of use and performance can be improved when more memory is made available to them. The following benefits can realized:
- Reduced I/O operations
- Reduced CPU usage
- Improved transaction response time
- Potential cost reductions
Although the magnitude ... [more]
