3 Introduction iternity is an highly scalable compliant middleware addressing the needs of small, medium-sized and enterprise customers. This is reflected in the solution s attractive price, practical maintenance-free operation, compatibility with existing servers, SAN, NAS and other backup structures, and transparent data handling. The iternity API is available over the web service SOAP protocol. The iternity middleware provides value-added function such as content addressable storage, encryption and compression. Content addressable storage means that the iternity middleware calculates a fingerprint based on a crypto graphical hash and returns this hash to the application for referencing the object. The iternity engine is stateless running without any database, this enables a migration and restore by simple file copy. iternity stores the data in a file system which can either be a local file system in the server or a file system created on NAS (N series), DR550 FSG and SAN storage(ds4500). iternity also provides load balancing and backup functions. With the load balancing function the iternity client such as the iternity MiniArchiver can be configured to write the data to two instances of iternity. When one instance of iternity is not available, the other instance is able to access the data. Thereby the data is not duplicated. The backup function allows to create two copies of the data. iternity can be configured to write all data to two distinct storage systems. If one storage system fails then iternity can be configured to retrieve the data from the remaining storage system. This document summarizes the tests which have been executed on 7/17 and 7/18/08 in the SLE in Mainz. In the course of these tests iternity has been tested on IBM System x and the data was selectively stored on IBM N series N3700, IBM DS4500 and IBM DR550 File System Gateway. iternity plans to submit three applications for the IBM System Storage Proven program, one for each storage system scenario and of cause for the IBM System x. Test Results Tests with iternity Software and IBM System x and IBM System Storage has been executed on in the System Lab Europe at IBM in Mainz. The test results are backed up by screen-shots in order to demonstrate correctness. All tests have been executed successfully and the expected results were met. Test Setup The following picture shows the setup for the testing including the resource addresses and names. Web location of document ( Page number 3

9 History of one of the CSC Containers: Read back one of the documents: Data Integrity Test Now we used an editor to change the data of one container to manipulate one container, and try to reload it. The result is that this test failed because iternity identified the manipulation. Web location of document ( Page number 9

With first test one DS4500 controller has been set offline.

29 Storage Error Injects With this test case different errors have been injected into the storage systems making it more or less possible to retrieve data. DS4500 Path Failover The DS4500 comprises two controllers representing redundancy. With first test one DS4500 controller has been set offline. Thereby the multi path driver (RDAC) included in the server hosting the iternity application performs a path failover. Write to DS4500: Set one DS4500 Controller offline and read.
