RECT™ Failover - downtime under control

Increased resilience, calculable maintenance expense: challenge unforeseeable risks with RECT Failover solutions

Your server is a vital part of your IT infrastructure, maybe even the centerpiece of your enterprise. It’s in charge of essential tasks and it administrates productive data. Data you want to be able to access at any time. Be it a redundant power supply, registered memory with ECC, RAID drives certified for 24/7 operation with particular low fault rates or cache protection for RAID controllers featuring state-of-the-art condensators instead of batteries: Servers branded RECT are full of smart and countlessly proven ideas for higher productivity and an all-round carefree hardware life cycle.

A comprehensive safety concept also covers the server as a whole, not just the components assembled within. Hence, failover solutions by RECT allow you to keep cool when hardware needs to be maintained or challenging tasks like complete rollbacks appear on the agenda. Now the time for service operations like firmware upgrades or employment of new hardware can be coordinated professionally.

Depending on the actual requirement profile of your enterprise, we offer an elementary solution (Cold Spare) and our sophisticated Replica Cluster, the latter aiming at even higher availability by combining consequent hardware redundancy with the unbeatable advantages of the latest virtualization technology in Microsoft Server with Hyper-V.

Replica Cluster - active resilience

The Replica Cluster is an automated double-decker server solution comprising a primary server and a replication server, featuring an integrated security concept with Microsoft Hyper-V to make your data available redundantly, and keeping the maintenance expenses to a minimum.

The solid plus factor for resilience:

Replica Cluster for all planned and unplanned failover scenarios.

The Replica Cluster is a tailored bundle comprising two redundant nodes (primary server and replication server), running pre-configured instances of Windows Server 2012 R2 with Hyper-V.

The primary server and the replication server run synchronously, while the replication server acts as the (active) primary server’s surveillant: if the primary server goes offline, the formerly passive replication server instantly takes over the primary role.

Ambitious work environments gain considerable amounts of resilience and fault tolerance. Ostensibly, the Replica Cluster presents itself as a single server in your network. However, the data is actually being stored redundantly by the replication server in the background. Hence, data is available on both nodes simultaneously.

In practice, the Replica Cluster is far more than just a safety belt for unplanned failovers, as they may occur in the course of hardware faults or errors in the operating system. Its benefits also apply to planned failovers due to regular maintenance works or necessary upgrades to the hardware and software. You can now schedule the required steps in a really structured manner, and you can take care of everything during the usual business hours, without even bothering the normal operation.

Cold Spare - the simple solution

If your server fails due to a hardware error, you can make use of an equivalent replacement you have in store. Only several steps have to be taken care of to keep the outage relatively short and your mind free for diagnosis and recovery.

Simple solution in case of emergency:
Cold Spare as a quick replacement


This is the simplest solution when it comes to improve availabilty. All you need for this kind of a stashed replacement is a server system identical in construction to your regular server, but without hard drives. If your regular server needs maintenance, you switch the hard drives of your regular server over to the Cold Spare Server, connect everything and power it up. When the Cold Spare has taken over, you can devote yourself to the retired machine and prepare it for reinstatement.

What options are there?

The RECT Shop with configurator offers the Cold Spare option for virtually all RECT systems. We recommend hot swap trays to make the transfer of any hard drive as convenient as possible. Also, it’s crucial to ensure a certain level of redundancy throughout the machine per se. Failsafe hard drives in a RAID configuration as well as a redundant power supply are essential components for improved reliability. There are still factors in the setup that cannot be fully safeguarded with built-in redundancies. You might want to take a look at our Replica Cluster if you’re interested in a more comprehensive approach. In comparison, Cold Spare would be the budget solution. Downtime can be reduced and resolved with several manual work steps.

What else is to know about Cold Spare?

To make the switch from one server over to the other as easy as possible the Cold Spare should be preferably identical to the regular server. Elementary components as mainboard, controller and backplane should be identical concerning type, revision and firmware. Everything else is subject to an appreciation of values (for instance a budget power supply for the Cold Spare). Our recommendation would still be an identical configuration only without the hard drives. In the course of replacing your regular server with a Cold Spare, software licenses need to be transferred as well. If you want to reduce the hassle, you should configure the Cold Spare coequally to the regular server. This way, you can just trade off the roles of the two machines without suffering a loss in either power or security, and you can keep the restored server as the new emergency backup.
