SNIA_SDC_2014_Title.jpg

Storage developers and professionals around the globe gather at the SNIA (Storage Networking Industry Association) Storage Developer Conference, Santa Clara annually to discuss on latest technologies, tools and tactics that is needed in Data Storage and Management. Also, we all know staying current with the latest technology can amount to good use of our dollars and time. It is the 11th iteration of the conference and was a 4 day event this September which was attended by 480+ professionals from our industry.

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...

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.

The pace of technological change and its complexity is challenging traditional business continuity paradigms.  What was once considered a ‘Best Practice’ in Business Continuity (BC) no longer serves the new digital-world and organizations can’t rely on these outdated processes to reach their future objectives.    These ‘best practices’, and the standards/guidelines which are based on these best practices are unsuitable for the modern technologically-dependent organization because they were intended to serve a different purpose within a vastly different business environment. Some might question or be puzzled by the notion that long-standing and widely-accepted best-practices could be unreliable, however, that really shouldn’t be so disturbing. After all, ‘Blood-Letting” was once a medical ‘best practice’; one that no so long ago lead to the death of our first US President.  It is time to modernize Business Continuity and align to the genuine...

I hear it more and more from IT professionals, "our key 'X' application just can not go down."  As you can image, the "X" variable in the prior sentence usually stands for a key business service or application running in the data center.  It might be cusotmer or partner facing website such as an ordering or reservation system, or it might be a service that internal employees use on a regular basis to do their job and keep operations going.  Regardless, if the "X" is down, heavy costs are incurred and someone may be in trouble.  

If you are thinking about how to keep your business up and running, check out Symantec's new Business Continuity homepage called "Run Business Run."  If you have a business continuity or disaster recovery project on the table, you can use the information on this page to give you the key concepts to consider before you...

The modern organization is highly dependent on information technology, simultaneously and quite unintentionally, information technology has introduced new exposures which have deceptively seeped into every layer of the financial organization.  The likelihood that an organization will experience a catastrophic loss from an IT-service interruption caused by an IT issue is far greater than an interruption coming from some disaster or ‘black swan’ event.  Still, the key to survival is allocating the appropriate amount of resources to the “right” risks; while that may include planning contingencies for a worse-case scenario, to be rational about risk more guidance regarding the investment tradeoffs that mitigate risk.

The “Big Question” is how to optimize scarce resources today, to achieve the greatest reduction in future losses.  The Big Question two components: (1) which risks are the serious ones and...
