Data Center Disaster Management is always driven by what happened to data centers with the arrival of an unexpected disaster. There are unmodifiable factors. If you leave the context of large enterprises, protection from disasters of bigger magnitude is difficult to set up for SMEs, because of higher costs to be incurred in proportion to the likelihood of the occurrence of the event. The article focuses on Data Center Disaster Management which are difficult to manage.
Data Center Disaster Management : The Situations
The argument is complex to get a clear idea of what might happen in any Data Center at Disaster, but we will try to point out the basics in a few lines. Data Center Disaster Management is not a problem for the technological infrastructure, or at least not primarily to the big brands. The majority of the companies today are small to medium, where budgets tight to the IT culture is limited. This makes them to depend on other bigger few brand’s colocation server or rented data center. This actually solves many issues as the number of problem sufferers becomes less in number.
On the other hand, many bigger companies do not have a Data Center Disaster Management plan and even fewer have a business continuity plan. Most companies make backups of dubious consistency which maintains the in same site where the infrastructure has to be protected. Those who re-read and copy these data to a remote site are a small minority. If we go on to analyze the possibilities of data replication, there are no particular limits of technology: there are good solutions available with bandwidth of WAN acceleration / optimization often supported directly by the suppliers of storage solutions that optimize protocols such as iSCSI . Even here, however, is almost never a technical limitation but processes. Obviously costs are always a function of RTO and RPO to be obtained but few companies who need to share at time ithout losing any committed transactions. The true cost of the Data Center Disaster Management is never something to be found (only) in the acquisition cost of the infrastructure but all that is necessary is to maintain and continuously test the Data Center Disaster Management plan.
Data Center Disaster Management : Tools of Trade
There are many tools to ensure Data Center Disaster Management, all pare rovided by the infrastructure providers, among them cloud computing plays a key role. The apparatus weak Italian SMEs not prepared to use them roughly because of high costs to be incurred, which suggests that when there was an earthquake or Emilia Eagle departed from many of the companies have been caused from the absence of precautions to safeguard corporate data at least, if not the business continuity.
One can make plans as complicated as they want to design countermeasures against each kind of event, but in practice to find the right balance between how much redundancy and how customers will want to have is a big issue. Beyond a certain point, it is usually more cost effective to design the redundancy of the service to a higher level of the individual server or a data center. For our part, we can provide services in two completely independent data centers in different regions, and in fact we have customers who take advantage of this opportunity with infrastructures that allow you to direct your customers to a data center or the other.
So far cloud computing can be an additional tool for planning a disaster recovery. The classical solution may be to use an IaaS infrastructure as an alternative to a CED and to prepare a replica on cloud.
