Update your Linux driver for Areca ARC-1883 SAS RAID Adapter


Recently, when performing planned test scenarios with different hardware parts, our QA team identified an issue with kernel panic during read operations on the Areca ARC-1883 SAS RAID Adapter. We notified Areca and thanks to their fast reaction we were able to quickly resolve the problem. Here’s an overview.   The problem During sequential read operations kernel panic occurred on Linux. As it turned out, the newer the kernel version the faster the system would […]


D2D2T: a disk-to-disk-to-tape backup strategy


A look at the modern data storage industry can make your head spin. From a variety of hard drives, efficient disk arrays, magnetic tapes, conventional or emulated tape libraries to such miracles of modern technology like RDX formats. It appears that you have a lot of choices – but this can be very misleading, especially when you take a closer look at the very bottom. Then you find out that almost always there is a […]


Is your Heartbleeding?

OpenSSL Heartbleed bug

The Heartbleed bug, officially referenced as CVE-2014-0160, is already being coined as one of the biggest security threats since the mass adoption of the Internet – affecting millions of websites and services, including credit-card numbers, email accounts and a wide range of online commerce. Heartbleed is a security bug in the OpenSSL cryptography library, which is widely used to secure Internet sites and applications. The OpenSSL “Heartbleed” vulnerability allows hackers to steal information protected by […]


Criteria for selecting files when performing full, incremental and differential backup

files for backup

A fundamental function of backup and restore software is the ability to copy data from one place to another. No matter if the backup data are stored on volumes, files, images or on magnetic tapes – we assume that data are being copied from location A to location B. In case of data loss in location A, a backup program should change the backup location and copy the data from location B back to location […]


CeBIT 2014: Datability with Open-E storage management software


Open-E just spent a fantastic week at CeBIT and here’s a review of what has happened during those five days in Hanover. Open-E and Datability One of the keynote topics of CeBIT 2014 was “Datability” which describes the ability to use and process huge quantities of data – quickly, sustainably and responsibly. As a Linux-based data storage software, Open-E DSS V7 fit this theme perfectly as customers are able to sustainably use commodity servers to build […]


What can we expect from CeBIT 2014?


Once again, Open-E is heading over to Hannover, Germany in March. But for a few reasons this CeBIT is special and we just can’t miss the No. 1 event for the digital world. The future of cloud computing: Top theme at CeBIT 2014 According to CeBIT: “90% of the population now use cloud services (for example via Facebook, Google or Amazon)” but only “around a third still think this technology relates in some way to […]


RAID Solutions made easy!

RAID solutions and resources

An essential element of the data availability architecture is RAID. With a RAID configuration, you can achieve redundancy, lower latency, higher bandwidth for reading or writing, and recoverability from hard-disk crashes. Following our recent webinars, showing different RAID solutions, we decided to put together helpful RAID resources for you. With them, it will be easy to set up different RAID configurations using our data storage software Open-E DSS V7. RAID levels explained: RAID 1, RAID […]


iSCSI storage: a beginner’s guide

beginners guide thumbnail

Storage management for ever-growing capacity of data is a crucial subject for businesses of all sizes. Simple and reliable storage based on iSCSI can be a good alternative for companies looking for cost-effective and easy to manage solutions. iSCSI is a native TCP/IP protocol used for establishing and managing connections between IP-based storage devices, hosts and clients. Open-E Data Storage Software V7 is used for setting up and managing data storage servers. Its design is […]


Diary of an admin: Backup and Data Replication


Replication, as a way of creating an exact data copy between the source storage location and the target location, is often erroneously put into one bag with backup. Despite of the fact that in both cases we can talk about ‘data copies’ – backup and replication cannot be treated as synonyms. Among many technologies that increase data storage protection, the term ‘replication’ is used very frequently. When you use block or file-based replication, a mirrored […]


Why RAID is not a backup


Today I would like to discuss the topic of RAID – more specifically backup issues. In the blog post title I proposed a daring thesis which I would like to develop and, as far as I’m able, to prove or defend it. At the very beginning, a few definitions and terms related to RAID have to be introduced, so the readers who aren’t familiar with RAID won’t feel confused. What is RAID? RAID technology extends […]
