It’s quicker, it’s lighter, it does not generate any noise and has a lower work temperature…Furthermore, it doesn’t have any mechanical, moving components so it offers you not only a very short response time but also great resistance to any shocks. So isn’t SSD the answer to all our storage needs that we were waiting for? So why should we even consider using SSD if the advantages over traditional, magnetic hard drives are so obvious? [...]

What to do with old hard disks? What to do if your company is going to upgrade its equipment? How to get rid of any useless hardware? However we approach these problems, everything will always concern one important issue – the protection of confidential data. Data security policy Briefly and generally – data security policy is a set of precise rules and procedures created to organize the resources of a company including the issues of [...]

Here we present two ways of thinking about the issue of boot media in cooperation with Open-E DSS V6. Take a look below – there are following options to consider: The first is to use a Small Boot Volume that resides on the Hardware RAID controller. This is a very reliable and stabile boot media and there is no need to buy an extra boot media. The small 2GB logical volume on the RAID Array [...]

Here we are with the next part of our RAID series. This time the article will concern RAID 5, RAID 6 and two alternatives – RAID 5E and 5EE. Take a look… RAID 5 RAID 5 is one of the most popular implementations. It works almost the same as RAID 4 but with one difference. The parity bits are not recorded on a specifically prepared disk – they are dispersed throughout the matrix structure. What [...]

Want to reduce energy costs and the risk of possible data loss? A dynamic increase of data volumes leads to greater the hardware requirements and greater power consumption – forces us to search for new solutions that can reduce the costs associated with this. So, every new chance to significantly reduce energy costs because of hardware power usage and cooling requirements is more than welcome in most organizations. The same goes for every additional possibility [...]

After RAID 0 and RAID 1 (with RAID 1+0 and RAID 0+1) it is time for RAID 2, 3 and 4. Here we present a small description of the mentioned levels. We hope it will outline a picture of the functionality of these solutions. Although the article is a kind of history lesson – these solutions are no longer used – it is good to be aware of the origins of modern storage technologies. RAID [...]

This is the second article from our RAID series. We hope it shows – in the easiest possible way – what RAID is, the idea of it and how it works.  We wrote about RAID 0. Now is the time for RAID 1, RAID 0+1 and RAID 1+0. What is RAID 1 RAID 1 (stripping or mirroring) – the basic idea of such a solution is the replication (mirroring) of two or more discs. It [...]

We published an article about RAID 5: “How does RAID 5 work? The Shortest and Easiest explanation ever” – now is the time for the whole series.  We will try to show you, in a few words, the shortest explanation for RAID standard levels – 0, 1, 1+0, 0+1, 2, 3, 4, 6 and Matrix.  Now is the time for RAID 0 – take a look… What is RAID 0 We can describe RAID 0 [...]

Hardware failure can be a show stopper for any shop without proper backups and hardware reserves. It can be very costly to send hard drives for data recovery. Even with a proper backup plan in place, failures can happen. To mitigate some of the headache, and expense in drive recovery, and downtime. We highly recommend data replication to another node, or volume replication to another DSS node be deployed. With replication in place, a real [...]

While you are using WAN network you may face the problem of slow connections. It may cause various difficulties – i.e. during replication process. Open-E Data Storage Software – as a professional and versatile product – has been designed with solving this problem in mind.   Synchronous or asynchronous? This is the question. There are two different cases. The first one is connected with block based volume replication. It is based on synchronous volume replication [...]
