Add deduplication and compression to an Linux server

12 September 2016
Comments off

Reading Time: 2 minutesAlthough Linux is used in several storage solutions, the native filesystems lack of modern features like deduplication or compression (compression extented attribute is present from some decade, but it’s implementions is still limited or missing). Most storage solutions use other filesystem (like ZFS), or also other operating systems: FreeBSD, NetBSD, OpenSolaris branches, or also Windows Server (like DataCore). Now Permabit Technology Corporation announced the availability of its Albireo Virtual Data Optimizer (VDO) for Canonical’s Ubuntu Server.

Top 10 safety tips for Cloud Backup

9 March 2016
1 comment

Reading Time: 7 minutesMost of us have a love-hate relationship with our data backup services: we love having a physical copy of our data, all on one hard disk system. But by nature, HDDs are prone to failure, and we end up losing most of our backup data in the process. Thankfully, one great solution is the cloud backup system! After all, it’s cheap, it’s convenient, and most importantly, it’s almost future-safe. Of course, we’re all paranoid about cyber theft and hackers, but if you follow these ten tips you will have absolutely no reason to worry.

Are public cloud services really cheaper?

18 September 2015
Comments off

Reading Time: 5 minutesOne myth of public cloud services is that is cheaper compared to private services, but it’s (or it could be) wrong. The reality is that you don’t have CapEx and you have usually monthly OpEx. But in the long (or sometimes also in the short) term could become more costly rather than an on-prem solution. Of course it depends by the service type and the real OpEx cost of your on-prem solution (sometimes not so easy to evaluate). But also public cloud services may have some costs that are not so easy to be evaluated […]

Frame vs. frame-less storage

28 July 2015
Comments off

Reading Time: 2 minutesOne old (and now quite not used anymore) storage concept was about the Frame vs. frame-less architectures. Those terms are from the past decades and where used (especially from Dell-EqualLogic) to identify how storage controllers are dedigned and how they can scale: Frame-based storage contain individual components that scale independently (you can add more cache, network connections, disks, software, etc.) until it’s maxiums and until the product is still supported. Usually you have two storage controllers and one ore more shelves of disks. Frame-less storage is modular where each “module” include it’s own storage processors, […]

What are Erasure Coding and RAIN?

26 June 2015
Comments off

Reading Time: 4 minutesWhen you talk about data protection against hardware failure in storage system, probably RAID (Redundant Array of Independent Disks) is the first technology that you think. RAID could be hardware or software based, and in the second case it can be implemented (with functions similar to RAID, but not necessary the same) also at the filesystem level (think about ZFS, for example). But with the new hard disk drive (HDD) capacities edging upwards (6TB HDDs are now available) the traditional RAID is becoming increasingly problematic both for the rebuild time and the bottleneck related to each single […]

Some useful IT posters

15 January 2015
Comments off

Reading Time: 3 minutesDuring IT events like VMware PEX, VMworld, VeeamOn, TechEd, … usually is possible collect some useful posters about specific technologies. Some of them are really valuable and printed on good paper and can become an office must (and another good reason to attend at those events). But most of them are available also for download, so if you miss one of those events or you need an additional copy you can simple download the poster that you need. Of course, in this case, the printed version could not be so useful (unless you have a […]
