By | Data Reduction, Deduplication, Flash Memory, Networked Storage, Solid state storage Flash Memory SSD, SSD, SSD Storage Systems, Storage Systems | No Comments

The use of data reduction technologies such as compression and deduplication to reduce storage costs are nothing new. Tape drives have used compression for decades to increase backup data densities on tape while many modern deduplicating backup appliances use compression and deduplication to also reduce backup data stores. Even a select number of existing HDD-based storage arrays use data compression and deduplication to minimize data stores for large amounts of file data stored in archives or on networked attached file servers.

One of the more difficult tasks for anyone deeply involved in technology is the ability to see the forest from the trees. Often responsible for supporting the technical components that make up today’s enterprise infrastructures, to step back and recommend which technologies are the right choices for their organization going forward is a more difficult feat. While there is no one right answer that applies to all organizations, five (5) technologies – some new as well as some old technologies that are getting a refresh – merit that organizations prioritize them in the coming months and years.

The Right Deduplication Method for the Right Data: Interview with Sepaton’s Director of Product Management, Peter Quirk, Part III

By | DCIG, Deduplication, Disk Based Backup, Uncategorized | No Comments

Anyone who is close to backup recognizes that some types of data deduplicate better than others. However trying to translate that understanding of the environment into meaningful backup policies is almost impossible since it is both complicated and time consuming to successfully implement. Using the new Sepaton VirtuoSO platform, it is able to choose the best form of deduplication for each backup stream on the fly. In this third part of my interview series with Sepaton’s Director of Product Management, Peter Quirk, we discuss how its VirtuoSO platform detects the nature of incoming backup data and then automatically invokes the best deduplication method to deduplicate the data.

Bringing Together the Best of Today’s and Yesterday’s Backup Technologies; Interview with Sepaton’s Director of Product Management, Peter Quirk, Part II

By | DCIG, Deduplication, Disk Based Backup | No Comments

A trend that DCIG is seeing among more new products being introduced into the enterprise space is the proclivity to use the best of what has been previously developed in the past and combining that with new technologies that meet the emerging requirements of today’s organizations. The new VirtuoSO offering from Sepaton reflects this broader industry trend. In this second part of my interview series with Sepaton’s Director of Product Management, Peter Quirk, we discuss what features Sepaton brought forward from its existing S2100 product line and what new features its VirtuoSO platform introduced.

Databases and VMs Only Now Fully Leveraging Disk-based Backup Targets: Interview with Sepaton Director of Product Management Peter Quirk Part I

By | DCIG, Deduplication, Disk Based Backup, Virtual Tape Libraries | No Comments

Ever since using disk as a preferred backup target gained momentum in the late 2000’s, there have been those who opine that disk’s life in this role would be short lived. But those providers who deliver disk-based backup solutions and are betting their future on them see no slowdown in their adoption. In this first interview with Sepaton’s Director of Product Management, Peter Quick, we discuss how databases and virtual machines (VMs) are just beginning to take full advantage of the benefits that disk offers as a backup target.

Maturing Deduplicating Backup Appliances Still Offer Plenty of Features for Organizations to Evaluate

By | Data Protection, DCIG, Deduplication, Disk Based Backup | No Comments

As DCIG prepares to release a number of Buyer’s Guides on Midrange Deduplication Backup Appliances in the next few weeks, we thought we would share some of our observations that came out of our evaluation of these products. Like all Buyer’s Guides that DCIG prepares, it did a comprehensive review of available deduplicating backup appliances in anticipation of releasing these Guides. As it did so, it uncovered that deduplication itself has moved well beyond the breakthrough technology that it was a decade or so ago to provide an assortment of features there leaves plenty for organizations to consider when buying one of these appliances.

Sub-millisecond Response Times are the New Gold Standard in Storage System Performance; Interview with Tegile Systems VP Rob Commins, Part I

By | Data Reduction, DCIG, Deduplication, Flash Memory, Storage Systems | No Comments

It was not that long ago – like no more than five (5) years ago – that if as a storage administrator you could configure a storage system to provide average response times of around 2 milliseconds for any application, you were a hero to everyone you supported. Fast forward to today’s hybrid and all flash memory systems and 2 millisecond response times are the new “slow.” In this first installment of my interview series with Tegile System’s VP of Marketing, Rob Commins, we discuss how hybrid and all flash memory are redefining the “Gold” standard for performance in storage systems.

Five Questions to Ask and Answer Before Buying a Backup Appliance

By | Data Protection, DCIG, Deduplication, Disk Based Backup, Virtualization | No Comments

This past week I received an email from someone asking for my help in their process of buying a backup appliance. This individual had just downloaded the DCIG 2012 Backup Appliance Buyer’s Guide but, due to the number of models included in the Buyer’s Guide (over 60), was looking for some recommendations from me as to which one to buy. While I sent this individual a list of backup appliances to look at more closely, it brought to my attention that there are five questions every organization should ask and answer before buying a backup appliance.

CommVault Takes a Single Pass at the Big Data Management Problem

By | Commvault Systems, Deduplication, SRM | No Comments

It’s no secret that ‘Big Data’ is becoming a ‘Big Problem’ for organizations from a data and storage management perspective. However what organizations may fail to realize is that the best way to solve their Big Data problems is NOT by mindlessly throwing more resources at them. Rather it is to look at Big Data more strategically and then tackle the data management problems it creates in one fell swoop using software like CommVault® Simpana® and its OnePass technology.

The Virtual Machine I/O Blender Problem – What It Is and How to Fix It – Virsto CEO Mark Davis Interview Part II

By | DCIG, Deduplication, Virtualization | No Comments

Companies are adopting server virtualization at an accelerating rate each year and, as they do, the need for performance on the back end hardware is growing right along with it. To accommodate this, enterprises need a way to increase the I/O throughput of their virtual machines (VMs). Today, I continue my blog series talking with Virsto Software CEO Mark Davis where we discuss the VM I/O blender problem, what it is and how Virsto boosts VM performance using a hypervisor plug-in that is up to ten times faster than what VM hypervisors natively provide.

EMC’s Emergence as a PBBA Juggernaut Turns Out to be a Best Case Scenario for ExaGrid

By | Data Protection, DCIG, Deduplication, Disk Based Backup, Storage Systems | One Comment

A little over two (2) years ago I did an interview with ExaGrid System’s CEO Bill Andrews about the same time that EMC and NetApp were engaged in a bidding war over Data Domain. In that interview Andrews expressed concern about EMC winning the battle for Data Domain and how that might negatively impact ExaGrid. But as EMC and ExaGrid both respectively announced overwhelmingly positive numbers this week, it turns out that EMC’s acquisition of Data Domain has served both companies well.

Cloud Storage, Deduplication and Post-Production Data Management Topics are Runner-ups in 2011

By | Cloud, DCIG, Deduplication, Virtualization | No Comments

Before DCIG announces its top three blog entries of 2011 tomorrow, this year we thought we would do something different and take a look at some other blog entries that garnered a great deal of attention throughout 2011 but not quite enough to reach the Top 10. That being the case, an honorable mention for these blog entries was in order. Further, what is notable about these entries is that, with the exception of one, they were all published in 2011.
