Performance Implications of Cloud Computing

Just found the IBM RedPaper publication providing a clear view of the cloud computing model including description of:

• Types of services and cloud delivery models
• Cloud roles
• Cloud service-level categories and Key Performance Indicators

This publication will help the end customers, system integrators and cloud providers to simplify the cloud services implementation process and make it more transparent.

The IBM RedPaper “Performance Implications of Cloud Computing” can be found here.

IBM XIV Gen3 Announcement

20 July 2011 IBM announced a new version of XIV Storage System which is up to four times faster than previous models.

The new XIV has the following improvements:

• InfiniBand interconnect  
• 8Gbps Fibre Channel ports 
• More memory

An optional feature that IBM plans to make available early next year that is designed to allow clients to non-disruptively add a solid-state drive (SSD) caching layer to XIV Gen3.

Also some software enhancements have been made:

• Enhanced, centralized administration of multiple XIV systems;
• XIV Plugin v2.5 for VMware vCenter ™ Server

Let’s see what will be next step? May be more tight integration with SVC and StorwizeV7000?
