Learn the Top Reasons Behind Poor Performance & Availability With Microsoft Exchange
As a professional, your clients know they can count on you and that you are including them. But what happens when the technology is not there, right? Imagine a phone with the customer, giving them great pride to finally have a document that has been waiting for is ready. During the chat, you add a document by e-mail is out. . . and wait.
And wait. E-mail is no longer in the folder, and not the mailbox. When you double-check e-mail, and as the conversation becomes increasingly uncomfortable, the client will confirm that the document actually exists, and there was really sent by e-mail. He is disappointed, and you have a complete loss. You decide we can no longer wait, and change your personal Hotmail account to resend the document, which may or may not work either now. The result is wasted time, and if you are in a system of e-mail is no longer required to change a single register.
The system administrator has been listed several reasons for this incident happened for reasons beyond its control:
The real reasons may actually covered a much deeper, which means that the loss of mail is not an isolated case.
Forgot your letters mean lost opportunities
Consumers, accustomed to quick responses from the Internet, is rapidly losing its tolerance for a slow response to email. Proof that you can check a recent study by the WAV Group, which maintains the property, the first agent to respond to customer e-mail inquiry, 73% chance of business. The third response is virtually impossible. [1] Similarly, a study published in December 2008 and estimates that Vodafone lost opportunities for failure to respond quickly to e-mail the business a cost of about $ 27,000 a year. [2]
But e-mail, missing completely? This summer, Apple Corp., authorized to “lose” 10% of MobileMe subscribers for its email between 16 July 18 and July [3], the wave of blog posts popped up because of this problem, all the requirements of the customers lost jobs, loss of business. We tend to view e-mails from low cost, but it is clear that, if this fails, the costs may be surprising. Apple only comment that the problem was caused by “a serious problem.” What exactly happens to those letters rebel, delayed or lost?
There are dozens of possible reasons for the truth is that e-mail service delays and errors. Complex business-class email systems like Microsoft ® Exchange and Lotus Notes, there are many ways to build and configure the system. Some meet the highest standards, while others barely meet the minimum requirements. little effort, you can determine if the system is adequately configured to your liking.
High Availability
As the name suggests, high availability is a system or network that is running, or available, and the frequency of the high degree of certainty. Ceryx, Hosted Exchange provider has a high availability of one of its main themes. With data centers in New York and Toronto, have developed different technologies to replicate data in real time, and all messages can fail for more than half of another disaster, allowing them to do a real 100% ALS. While most providers tend to choose high-availability and high performance, all distribution Ceryx Microsoft Exchange is designed to meet the highest standards of uptime availability without sacrificing performance.
A criterion for testing application performance service provider login webmail application, and open the mail, check your calendar. Choose a folder with many messages and try sorting “talk” and then clicking through the pages. If there is significant delay between the application of these measures, the performance of your provider is not satisfactory.
Existence of a system is determined by many factors, each of which is discussed below.
Architecture
Delays are often the result of high latency RPC server. RPC Remote Procedure Call, as the client or the Outlook client or Outlook Web Access (OWA) servers to communicate with heat exchanger. RPC latency indicates the delay between the start and completion of the application. RPC latency, as demonstrated by the customer, is a combination of network latency and server latency. Good performance, Microsoft is a guideline 50 ms average latency of the server mailbox. [4] When the server RPC average latency of mailboxes, much higher than the PC user experience “pop-up and reporting connection problems with Outlook Exchange server. The context of e-mails into and exit is not processed because the system tries to catch up with other applications. Excessive pop-up “can become something more than just annoying, but can slow your computer is unusable at the same point Outlook tries to connect to server.
Ceryx RPC is intended to maintain the rate of 20 ms or less. To this end, they have a tendency to avoid the many suppliers who have built their own systems in virtual environments and less expensive network attached storage. Instead, Ceryx invested clustering of high-end servers and SANS (Storage Area Network) in each of their data centers. Sans offer performance disk access, as well as through redundancy RAID configurations and channel fiber connectivity to the server mailbox.
Many service providers to reduce costs, combined with Client Access Server and Hub Transport server (the server is used to facilitate e-mail service) on a single physical machine. This dual role can establish latency by using the stylus and the ability to manage large accelerator queues outgoing mail. Ceryx Hub Transport role is designed to ensure that message queues can be cleared quickly, even during periods of heavy load. Combining a number of which is dedicated to physics Hub Transport server functionality built-in round-robin load balancing Exchange 2007, messages are quickly distributed destination on the Internet. For legitimate e-mail, load balancing hardware is used to ensure optimal performance of the critical role of transportation hub, which processes each message that passes through the system.
Monitoring
Most hardware load balancing configurations can ensure high performance and high availability, while maintaining high performance and high availability – with a dynamic system, such as distribution Hosted Exchange, where the user and the weight of a very different – have developed monitoring systems and procedures to scale the system in response to changing variables.
Some of the general monitoring of service providers to install the packages, which tend to track each counter existing metrics to provide an overview of the significant performance of the system or not. What Ceryx, every aspect of the essential features of the context around San queue length standard metrics like CPU and memory will be monitored, trends, and understandable. This information is used to develop a very accurate prediction of the proposed system, and scaling. Any supplier who did not invest in these funds and monitoring the use of nails for easy use and respond to the load. Ceryx these plans.
Breathing Room
Another important cause email delays and performance can be attributed to the recovery of basic economics. “Store” is a single database for storing data messages. Microsoft Exchange Server 2007 Enterprise with a maximum of 50 outlets with a limit of 200 GB recommended by Microsoft for each store. Some service providers seeking to maximize the number of customers grow, pushing the boundaries. Ceryx is not illegal. Ceryx maintains a maximum of 50 GB Store – up to fourth – in order to achieve the best raw database performance and protect data from corruption common in larger shops. These serious limitations exist, it is difficult to imagine how some of the providers – offering up to 4 GB mailboxes – will be able to run sustainable enterprises and to maintain high performance and availability.
IOPS
Economics may drive another reason for poor performance: IOPS, measure how many times you can read and write to disk per second, the system can be very different. Microsoft Exchange, the IOPS capacity is directly related to the performance and up to a heavy user of IOPS can be used in certain conditions. Each disc has the maximum number of IOPS can be argued that the relationship between people care about disk array, it is important to maintain decent performance.
Ceryx has been careful to maintain a generous ratio of IOPS per user based on real metrics to monitor their large user base, given the time of peak activity, not just daily averages.
Routing problems
To be honest, e-mail delays and errors may occur outside of their environment. Years, a scenario where you sit and wait for my colleague, was eager to get e-mail is not necessarily stuck somewhere in the “cloud” – somewhere between the two settings of your e-mail .
In terms of pre-sales support, Ceryx developed a set of tools that help troubleshooting to identify issues possible route. As with any application, hosted in the cloud “of bandwidth is an important consideration when trying to ensure a positive experience for end users. Microsoft Exchange, which uses 3 KB is an active Internet connection the customer is no different. Ceryx developed tool that simulates a number of network connections to determine if the client has sufficient bandwidth to support their user base. With these activities, they found that – for Any customer moves in the environment, hosted environment – increased bandwidth necessary to offset some termination and discharge of SMTP traffic, traffic, external links and spam attacks.
Spam / Anti-Virus
Sure, the message reaches the place of the infamous “stuck” or delayed, the provider of antivirus and spam filtering system. Ceryx runs on seven different antivirus products in their environment, to ensure that the health and status e-mail system. This level of protection would cripple ordinary system, which was not built in a high performance, but Ceryx is not only the size of its solution for the performance hit of anti-virus scanning light, but also to closely monitor its environment, to ensure e-mail that the delivery is not compromised spam and virus filtering.
Beware of any supplier or ignore the potential performance hit, or worse, remove all the back-end with the virus. The removal of the virus may seem like a good opportunity to control costs, such as quality solutions can be very expensive, but allows removal of the virus, and once, so it is often difficult to find, let alone remove them. Ceryx system analyzes the incoming and outgoing messages to save messages as expected. Regularly scan the mailbox database is as important as a gateway anti-virus gradually reduced as a catastrophic failure.
Mobility
Utility and usability Ceryx architecture can be measured not only at the desktop, but also for mobile users who share the same highly optimized, redundant and the environment. Ceryx also maintains fully replicated BES (Blackberry Enterprise Server), both in its environment to maintain maximum uptime and mobility. Forum Petroleum Equipment Services, Industrial, Houston, Texas, currently has 600 employees, using Ceryx Hosted Exchange solution, almost 100 mobile users.
Beware of “bargains”
Unfortunately, the market is crowded with Hosted Exchange providers that are not so interested in providing a reliable and robust as they are around to keep costs low and high volumes of mailboxes. Service providers that offer 3 or 4 GB of mailboxes are ignoring the widespread perception that the size of a mailbox does not fill well and is very susceptible to data corruption. That corruption is not limited only to the user, but can affect all users in order to maintain, potentially even the entire server.
These service providers may offer only the mailboxes and the size of the lower price if they are a compromise at the expense of someone else – dedicated servers, SANS, the anti-virus solutions, or a fully redundant architecture. It is obviously much higher cost of lost productivity and opportunity, which is the solution, which was the main objective of the proposed meeting of the lowest possible price point to compete with free market solutions, and the Enterprise does not offer the performance and availability.
Ask all potential suppliers of the following:
How is it measured?
Lost or delayed mail could be seen as a nuisance or a warning. Purchasing decisions must be financially responsible, but the solutions often appear to be positive can be devastating and costly impact on the long term.
As your bespoke system? Using Ceryx controls to measure the speed, versatility and durability of the system.
