SEPATON Performance Revisited

In this post, I highlighted SEPATON’s S2100-ES2 performance both with and without deduplication enabled. In a comment, I had also indicated that we would be adding additional performance information to our website and collateral and  am happy to report that the update is complete.  You can find our deduplication performance numbers on multiple different locations […]

SEPATON S2100-ES2 Performance

The SEPATON S2100-ES2 was designed for speed. Our solution is based around the concept of a unified appliance which provides one GUI for managing and monitoring all embedded hardware. We also automate the disk provisioning and configuration to provide consistent scalability and performance. The result is an appliance that can easily be managed by an […]

Deduplication, Restore Performance and the A-Team

I have posted in the past about the challenges of restoring data from a reverse referenced deduplication solution. In short, the impact can be substantial. You might wonder whether I am the only one pointing out this issue, and what the impact really is. An EMC blogger recently posted on this topic and provided insights […]

The Fallacy of Faster Tape

I often talk about disk-based backup and virtual tape libraries (VTL) and wanted to discuss physical tape. While VTLs are popular these days, tape is still in widespread use. LTO tape, the market share leader, continues to highlight increased density and performance. Do not be fooled with these claims. In the real world faster tape […]

Trials and Tribble-lations of Deduplication

One of my favorite episodes from Star Trek was “Trouble with Tribbles.” In the episode, Uhura adopted a creature called a tribble only to find that it immediately started to reproduce uncontrollably, resulting in an infestation in the Enterprise’s critical business err spaceship systems. You can read a synopsis of the episode here or even […]

Deduplication: It’s About Performance

I have recently been thinking about the real benefits of deduplication. Although the technology is all about capacity, when you analyze the cost and benefits in the real world, the thing that jumps out at you is performance. Performance is the key driver in sizing and assessing the number of units required. That means it […]

The hidden cost of deduplicated replication

On the surface, the idea of deduplicated replication is compelling. By replicating deltas, the technology sends data across a WAN and dramaically reduces the required bandwidth. Many customers are looking to this technology to allow them to move to a tapeless environment in the future. However, there is a major challenge that most vendors gloss […]

Data protection and natural disasters – Part 1

Hurricane Ike has been in the news lately and my sympathy goes out to all those affected. It is events like these that test IT resiliency. The damage can range from slight to severe and we invest in reliable and robust data protection processes to protect from disasters like this. The unfortunate reality is that, […]

InformationWeek on NEC HYDRAstor

Howard Marks recently posted an interesting article about NEC’s HYDRAstor over on his blog at InformationWeek. He discusses the product and how the device is targeted at backup and archiving applications. He makes some interesting points and mentions SEPATON. I wanted to respond to some of the points he raised. …[the system starts with] a […]
