O mundo do FSS

Com o lançamento da suite Symantec Storage Foundation 6.1 foi apresentada uma nova feature denominada FSS (Flexible Storage Sharing). Esta feature tem como objetivo uma quebra de paradigma. A possiblidade de implementar um ambiente de alta disponibilidade com ou sem DR sem a premissa de compartilhar os discos entre os servidores envolvidos.

Com a utilização do FSS é possível montar uma solução de alta disponiblidade sem a necessidade de compartilhar o mesmo storage, eliminando assim um ponto unico de falha. A partir desse momento a feature tem como objetivo sincronizar os dados via rede entre os discos de forma individual e não mais compartilhado, mantendo todas as garantias de integridade dos dados proveniente das versões anteriores do produto.

Ampliando a linha de atuação além de ter simplesmente um ambiente de alta disponilidade sem discos compartilhados, podemos pensar em diversos cenários para fazer uso melhor desta feature,...

According to Forbes, 70% of organizations that were in the Fortune 1,000 ten years ago have vanished.  The natural question is why did this happen?  The simple answer is business agility.  These organizations were not able to adjust to changes in the business environment and were eventually crushed by their competitors or by changing trends in the market.  

Look at Blockbuster for example.  In 1992, Blockbuster was the largest video rental leader with over 2,800 stores worldwide and by its peak in the early 2000s, Blockbuster grew to over 10,000 stores across the globe.  Then the business environment changed.   In 1997, a startup called Netflix was launched with a completely different business model.  Instead of opening brick and mortar stores that people could rent videos from, Netflix mailed DVDs...

Business Challenges

Businesses and organizations of all sizes have adopted virtualization as a core technology within their data centers. Both new and legacy applications are moving to virtualization because it reduces cost, improves hardware utilization and simplifies management. Originally, proprietary virtualization platforms were the dominant forces in the industry. Lately, customers have realized that open virtualization platforms provide higher performance, better functionality and are more cost effective.

The rapid adoption of virtualization has driven demand for support of High Availability (HA) and Disaster Recovery (DR) functionality. Businesses rely on an "always on" IT infrastructure in order to provide competitive advantage and create unique customer values. Applications built on virtualized environments must deliver appropriate levels of availability with minimal or no downtime.

Flexible Storage Sharing provides great capabilities to reduce capital and operational expenditures. In a previous blog entry I was describing how to commoditize high availability and storage using Flexible Storage Sharing. Later we saw in this article how to add an extra node to the cluster. In this blog entry I am going to describe my next step that was to have a database instance running in each cluster node. My idea here was to provide resiliency by having a mirror of my data and redo logs in at least two servers. With this approach, each node will have a local copy of the database that is running plus a mirror for another instance. This will be the architecture I will be using:

In the article Commoditizing High Availability and Storage using Flexible Storage Sharing I described my first attempt to create a two node cluster based on Flexible Storage Sharing within Symantec Cluster File System and the nice results that I got. My next step was to increase the node count as I wanted to move to an architecture where a database will be running in each of the nodes. The first step here was to add a new node to the cluster.

Many times I get the question about how easy or difficult is to add a node to the cluster. This was a good opportunity to document what I did here. Our engineers at the Common Product Installer (CPI) group have done a great job over the years and now adding a node to the cluster can be done with a few easy steps.

The first thing to do is deploy the packages on the new server. There are several ways to do...
