Enterprise Storage Networking Consultant

I have spent 4 years working within Nestle Switzerland involved with 3 projects

2009 GBSL (Global Systems Landscape)

I have just finished participation the Build phase of a new AIX based SAP ECC6 (ERP Central Component 6) level template.

I was part of a small team which built and installed over 150 AIX 5.3 TL8 servers on IBM P6 P595 technology running with Dual VIOS PowerVM based virtualisation. This included over 450 CPUs, 1900GB memory and 180TB disk. We also configured the TSM 5.5 servers within a Library Manager environment and their LAN and LAN free connections, and the Host side LANfree subsystems such as TDP. A challenging project.

2007-2008 L3 SAN Storage AIX Support

I provided Level 3 support in a pan European (and now Global) AIX and Storage Team responsible for 4 key areas of UNIX, SAN, Enterprise Storage, and Backup.

The scale of this implementation is worldwide, with over 1500 servers in our local European environment. I was directly responsible for a framework that includes over 30 mixed IBM DS8000 and legacy ESS subsystems often individually exceeding 100TB of storage, a dual fabric SAN using more than 40 McData Directors from 6140 to i10K, and a TSM backup subsystem with over 14 Enterprise sized 5.5 TSM servers with predominantly 3580, 3584, 3592 Tape Subsystems having upto 500 server systems per TSM server. These DataCentres are significantly more complex than IBM's internal DataCentres that I have grown up with.

We help implement one of the largest Global SAP implementations worldwide and our TSM backup servers are principally involved in the backup of the DB2 based SAP databases ranging in size from 400GB to 60TB Business Intelligence (BI). Over 200 individual SAP database systems are backed up every day to our TSM servers.

SAP systems with databases over 1TB make use of IBM Storage Agent to send daily Online database backups LAN free from their SAN connected IBM storage directly to 3592 TS1120 Jaguar and legacy 3580 Ultrium3/2 tape devices.

Larger SAP systems, for example the European 47 SD MM Database of 10TB or the European 20TB Business Warehouse system use IBM FlashCopy to make twice daily (!) full online DB2 backups. TDP for SAP transfers these backups to TSM using LAN Free Storage Agents.

We were responsible not only for the Installation and configuration of the TSM servers, SAN Networking, Tape Libraries and subsystems, but also the configuration of all aspects of TDP for lanfree backup. Once in production we are responsible for 24x7 Operations and problem resolution and trouble shooting.

2006-2007 ADDC Alternate Disaster Data Centre

The ADDC project remit was to design, document and implement a technology allowing Nestle replicate onlie critical SAP systems (e.g. SD MM BI) from 3 Global Datacentres to Switzerland to overcome catastrophic failure of any single Datacentre. The full project implementation was to online replication of over 40 SAP systems and over 120TB of data across three continents. In that context we used and configured Cisco MDS, WAE, IBM PPRC FlashCopy, Metro Mirror, Global Mirror Topio, TPCR TPCD, FC-IP routing, Shunra Storm

Besides Storage specific work I was involved in intense technical AIX Work including the IBM factory Build process and CSM. Working with SAP and DB2 we recovered tens of systems during DR prototyping.

Other works

I am determined to make sure everything is documented in a professional manner I have implemented a DokuWiki based departmental Wiki for AIX, DB2, SAN, Storage, TSM and SAP.

Other 2009 technical highlights include SAP consolidation and Virtualisation using VMware, early Cromemco Cromix restoration projects, the beta testing of Longhorn 2008R2, Windows Home Server and Ubuntu 910.
