Using Install Bundles to Simplify Storage Foundation HA Install and Upgrade
 

A new Install feature called Install Bundles has been introduced with the 6.0.5 and 6.1 Storage Foundation HA releases on Unix/Linux.  This feature makes it possible to install multiple SFHA releases in one operation.  This article describes three scenarios in which Install Bundles can be used to simplify the SFHA installation and upgrade process:

  • Installing or upgrading SFHA directly to a Maintenance Release (MR) level
  • Installing or upgrading SFHA with one or more Patch releases
  • Expanding OS Minor version support for existing SFHA releases

Installing or upgrading SFHA directly to a Maintenance Release level

Many Storage Foundation customers prefer that Maintenance Release levels (#.#.#) operate on their production systems for added stability.  However, nobody prefers the...

A few months back I was talking shop with a guy that is a high-level manager at another company and one of the things he said to me was "We've got a lot of VCS in our environment, but we don't really use it for anything. It's just deployed because at some point in the past, someone decided that it needed to be part of the build spec regardless of what the deployment was for"

I had to try really hard to not effuse too heavily all over him regarding the benefits of clustered systems and I've been pondering that ever since. I've been working in storage, and clustering, and clustered storage since 2007... you could say I'm a big fan. Here's a guy, though, who's never been really shown what clustering can do to help him and his company in their environment.

 

So... One-node cluster. Sounds like a dichotomy, like Jumbo shrimp. Once you stop and think about it, though, VCS provides an incredibly powerful opportunity for simplifying system management even if there...

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,...

VVR 6.1 introduces two new performance features:

  • Storage Replicator Log (SRL) Batching to improve application throughput
  • Bulk Transfer to improve replication throughput

Note: Both of these features are enabled by default in standalone VVR.

SRL Batching combines multi-threaded application writes to the same replicated data set as a single write to the SRL. Batching reduces the number of IOPS to the SRL thereby resulting in faster write access times and improves application performance. Moreover, this also translates into lower CPU utilization by VVR. In order to be effective, the batching algorithm accumulates multiple parallel SRL IOs before they are written to SRL in a batch.

Bulk Transfer replicates multiple I/Os in 256KB chunks when memory buffers are flushed to the SRL, increasing replication throughput and...
