Different types of RAID and RAID levels, advantages and disadvantages

One of the challenging tasks of every system administrator is to strike a balance between reliability and performance when choosing a dedicated server. Some might say choosing a rite Redundant Array of Independent Disks (RAID) option and level is critical, but what is RAID and why is it so important?

Wikipedia defines RAID as “data storage virtualization technology that combines multiple physical disk drive components into one or more logical units for the purposes of data redundancy, performance improvement, or both. ”  RAID should be considered as part of a business continuity plan and it improves reliability by replicating the data on one or multiple disks. It also improves the performance by enhancing the read write function from/to one or multiple drives. There are two main component in every RAID setup RAID level and RAID control.

Table below shows some of the most common RAID levels.  

Level Minimum # disks Redundancy Disk space utilization Read speed Write Speed Ideal Application
RAID 0 2 None 100% Fast Fast Image & video editing
RAID 1 2 Yes – 1 disk 50% Fast Moderate DB & critical data
RAID 5 3 Yes – 1 disk ~80% Moderate Slow Archiving
RAID 6 4 Yes – 2 disks ~70% Moderate Slow App server
RAID 10 4 Yes – 1 disk 50% Fast Moderate Critical data

In a nutshell RAID controller task is to control the RAID array, to make sure drives are working as the logical unit and computer recognize it as such. There are mainly two types of RAID controller, software and hardware RAID controller. Software RAID relies on computer CPU to control the read / write process, although sever CPU is supper fast these days but still it creates computation overhead and utilises server resources depending on the RAID level. Hardware RAID controller on the other hand is equipped with internal processor like ARM or ASIC to control the array.

Comparison table below shows some the advantages and disadvantages of different RAID types.

RAID Controller Advantage Disadvantage
Software Low cost, easier to reconfigure the array Slow, changing the failed drive is not easy, not suitable for RAID 5 & 6
Hardware card Faster read / write, replacing failed disk is easy Requires additional hardware
Hardware card+ cache Improves I/O performance Cost , susceptible to loss of data in case of power failure

Automatic and Rebootless Linux Kernel Update – KernalCare

The main responsibility of every system administrator is maintaining software and security updates, this can be a daunting task if you are managing multiple servers, operating in different time zone and hosting your server / VPS in multiple locations. You need to schedule a task with your clients/stakeholders, take the servers offline and apply the patches manually. If you are running a Linux OS (CentOS, Redhat, Ubuntu, Debian,…) now you can apply security patches automatically to a running kernel thanks to Kernel Care.

Cirrus Hosting is Happy to announce that we are now offering the latest version of Microsoft’s Windows Server on our Dedicated Server and Cloud VM / VPS plans. Windows Server 2019 comes with lots of new features and upgrades. Let’s take a look at some of them:


Improved Security

Microsoft has introduced a series of new security features to provide an additional layer of security. Advanced Threat Protection (ATP) provides features like auto investigation & remediation, endpoint detection & response, attach surface reduction and security posture. Microsoft is relying heavily on cloud computing, artificial intelligence and machine learning techniques to provide near to real-time security by pooling the data from the Windows Defender ATP and conducting threat analysis by aggregating the data from multiple sources. You can read more about ATP here.


Improved Windows Admin Center

Windows Admin Center (WAC) is the future of remote server management. It is a web-based console that enables administrators to manage the entire production environment – from on-premise to Azure to hybrid configuration through a single initiative panel.


Software-Defined Networking (SDN)

Greatly valuable in a virtualization environment, software-defined networking enables you to set up networking in your Hyper-V environment similar to what you can do in Azure, including virtual LANs, routing, software firewalls, and it makes life so much simpler for you. Windows 2019 provides ultra-high-performance throughput with much less CPU utilization; Microsoft also introduced many new security features to gain user’s confidence in running a hybrid infrastructure.


Storage Migration Service

If you managing an enterprise solution, Windows 2019 storage Migration Service is a new intuitive and super easy migration tool; it makes your life much easier if you want to migrate to the latest hardware or Cloud VM. I believe two new features storage replica and test failover are also going a long way to improve business continuity and makes life much easier to implement a hybrid solution.

All You Need to Know About Changes to Domain Privacy

Whois System and Why You Still Need Get Whois Privacy

When you register a domain name you are required to provide personal information such as name, address, email, and phone number. Your personal information plus your domain creation/expiry/update dates and registrar name are stored in an online directory called WHOIS and it is available to the public. Most registrars offer an add-on service called Whois privacy to mask your personal information.

Introduction of new EU General Data Protection Regulation (GDPR) changed the public Whois system as we know it. Registrars like many other IT service providers had to adapt and revise the way they collect and hand personal information in order to be in compliance with Article 5 EU-GDPR, “Principles relating to the processing of personal data”. As a result, ICANN proposed a new interim model called “gated access system or gated Whois system” under this model the domain registrant personal information is no longer published and replaced by “REDACTED FOR PRIVACY“. In this model, third parties with legitimate reasons like intellectual property lawyers, law enforcement, and cyber security professionals can still access your personal information.


You might ask do I still need to enable Whois privacy. My answer is yes, although your personal information is not available to the general public there are still many third-party organizations with an access to the gated Whois system that can access your full name, address, phone number, and email.
