Southwest Exchange

As a professional, you know that your customers can count on you, and you’re there for them. But what happens if the technology is not there for you? Imagine the phone with your client and said with great pride that the document is finally finished he waited. While you chat, create the document to an e-mail, please send it. . . wait.

And wait. E-mail is no longer in your Outbox and not in his inbox. Please check your e-mail and the conversation will be more embarrassing to ensure that the client is the document exists, and it was really an e-mail sent. He is frustrated and you’re at a total loss. You can decide not to wait longer and go to your Hotmail account to a personal document which may or may not work immediately, either re-send. The result is a waste of time, and if you e-mail system that you no longer turned on a continuous sheet of the Exchange.

Your system will list a number of reasons why this incident occurred, for reasons that are beyond its control:

The real reasons are actually much deeper, which means that it is lost e-mail will not be an isolated event.

Means the loss of opportunities lost emails

Consumers, accustomed to the rapid response by Web sites, are losing their tolerance for slow email replies. Evidence can be found by a recent study by the WAV Group, which is seen in the real estate industry needs to respond to the first agent to a client by e-mail application has a chance of 73% company. The third response is virtually no chance. [1] Furthermore, a study by Vodafone in December 2008, estimates that the opportunities lost because of failure to respond quickly to messages from companies costs about $ 27,000 a year by e-mail OUT. [2]

What about e-mail is totally absent? This summer, Apple Corp. admitted to “losing” 10% of their subscribers MobileMe e-mail between July 16 and July 18. [3] A wave of blog posts appeared after this problem, the loss of subscribers for all claims arising from job losses for businesses. We tend to e-mail as a low cost service, but it is clear they can not view the costs are exorbitant. Apple would say only that the problem was a matter “serious.” So, what happens to e-mails lost, late or lost?

The truth is, there are dozens of possible reasons for e-mail delivery delays and errors. In business class complex messaging systems such as Microsoft ® Exchange and Lotus Notes, there are many ways to create and configure a system. Some conform to the highest standards, while others barely meet the minimum requirements. With little effort, you can determine if your system is configured sufficiently to meet your needs.

High Availability

As its name suggests, high availability is a system or network, operational or available, with a high degree of safety and frequency. Ceryx, a provider of Hosted Exchange, has a high availability of their main priorities. With data centers in New York and Toronto, they have different technology to reproduce all the data in real-time messaging and may develop a failover to the secondary system in case of disaster, so they are a true 100% SLA. While most vendors to choose between high availability and high performance, all Ceryx Microsoft Exchange deployments were probably built at the highest level of availability of availability without sacrificing performance to do.

A measure for examining an application provider is able to connect to the webmail application, and switch between the E-Mail on the calendar. Select a folder with many messages and try sorting by the “Sender”, then click Sites. If there is a noticeable delay between these actions and the performance of your application vendor may not be appropriate.

A system availability is determined by many factors, each of which examined the merits.

Architecture

Delays are often a consequence of the high-latency servers PRC. RPC or Remote Procedure Call, is how the Outlook client or Outlook Web Access client (OWA) communicate with the server of the exchanger. RPC latency refers to the time lag between the initiation of an application and fill it. RPC latency, as seen by the client, is a combination of network latency and server latency. For good performance, Microsoft director 50ms average latency on the server mailbox. [4] If the latency RPC server mailboxes, on average, much more than that, can the desktop user experience, “pop-ups and warnings about problems with the connection from Outlook to Exchange server. In the background, incoming and outgoing e-mail does not seek to address the system catch up with other issues. Excessive “pop-ups have no more than a nuisance, they can slow a PC to the point of being unusable, while Outlook tries to connect to the server.

Ceryx seeks a rate CPP of 20 ms or less for the vertical. To do this, they have the tendency of many vendors that their systems with less expensive virtualized environments, Network Attached Storage built avoided. Instead Ceryx has in clusters of servers and high-end SAN (Storage Area Networks) to invest any of its data centers. SAN disk access performance and redundancy through RAID and Fibre Channel on the server mailbox.

Many providers, in an effort to cut costs, combine the Client Access Server and Hub Transport server (server used to facilitate the delivery of e-mail) on a single physical machine. This dual role can introduce latency in times of peak gas, bypassing the ability to produce large outgoing queues. Ceryx must assume the role of transportation hub message queues are cleared quickly developed, even in times of heavy load. The combination of several physical dedicated server transport hub with integrated load balancing round-robin capabilities of Exchange 2007 messages are quickly taken to their destination on the Internet. For legitimate e-mail is used by load balancing hardware to ensure optimal performance of the Hub Transport role essential that each message that passes through the system to ensure that process.

Surveillance

Most equipment can achieve load balancing configurations for both high performance and high availability, however, to obtain high performance and high availability – with a dynamic system as a Hosted Exchange deployment, use and where stress can be very different – have an advanced control system and process for the system-wide response variables changing.

Some vendors install to monitor packets generic control that tend to all the metrics available, if the parameters provide useful guidance to the implementation or not. Ceryx all aspects of the environment from key figures around the length of the queue San monitored closely for standard metrics such as CPU utilization and memory utilization, trend, and be understand. This information is used to make highly accurate forecasts and scale of the proposed system. Any vendor who does not invest in monitoring tools, and resources to respond only to the use and peak load. Ceryx plans for her.

Breathing Room

Another important reason for delays in mail and poor performance can be recycled in the fundamentals of the economy. A store is a single database to store messaging data. With Microsoft Exchange 2007 Enterprise is there a limit of 50 parts per server with a Microsoft recommended limit of 200 GB for each store. Some sellers try to maximize number of customers by offering support to those limits. Ceryx the opposite. Ceryx holds up to 50GB per store – one quarter of the maximum value – the performance of database best raw materials and provide protection against the loss of data, as well as department stores. available with these severe restrictions, it is difficult to imagine how some suppliers – Mailbox for up to 4 GB – are capable of carrying a sustainable enterprise and high performance availability.

IOPS

Economy may also be written another cause of poor driving performance: IOPS, a measure of the number of data and read from disk per second can vary within wide ranges depending on the system. With Microsoft Exchange, the IOPS capacity is directly linked to performance and a big user can have up to 1 IOPS, in certain circumstances. Each disc has a maximum number of IOPS can support it, while the ratio attention of users per array of hard drives is important to get decent performance standing.

Ceryx is eager to watch a lot of IOPS per user on actual data from its user base wide basis, taking into account both the peak of activity, not just daily averages.

Routing problems

Delays To be fair, e-mail and errors may occur outside of your environment. happens in the scenario in which your colleague sat eagerly awaiting an e-mail, it may be stuck somewhere in the clouds “- somewhere between the two environments e-mail.

On a pre-sale and the level of support, Ceryx has developed a set of troubleshooting tools to avoid potential routing problems. As with any application hosted in the cloud “of bandwidth is an important consideration in ensuring a positive experience, end-users. Microsoft Exchange, 3 KB of a customer uses the Internet connection active user , is no different. Ceryx has developed a tool that a number of simulated network connections to determine if the client has sufficient bandwidth to support the development of its user base. “Through this exercise, they found that – is necessary for each client moving environments on site to a hosted environment – does not increase the bandwidth partially relieved by the closure and SMTP traffic that does not compensate for the external connections spam traffic and can attack.

Spam / Anti-Virus

Of course, the most notorious place of a message is blocked “or is delayed in the fight against a supplier-virus and spam filter system. Ceryx runs seven different antivirus products in their environment to health and e-mail system to ensure hygiene. The level of protection could cripple an ordinary system, which was not built for high performance, however, was not just a great Ceryx their solution with the performance hit with the virus to mind, but is also closely monitors its environment to ensure email delivery are never affected by spam and virus filters.

Beware of any contractor who is unaware of these potential performance problems, or worse, just back-end anti-virus together. Removing Anti-Virus can obviously a good way to control costs, such as high-end solutions can be very expensive, but allows them to remove viruses and once in, are often difficult to find, delete what is not serious. Ceryx as planned, the system analyzes incoming and outgoing messages in the company. Regular analysis of databases of mailboxes is as important as Gateway Anti-Virus on the instance of catastrophic failure reduced.

Mobility

The value and usefulness of the architecture Ceryx is not measured only in the office but also for mobile users as well, which is the same highly optimized and redundant environment. Ceryx also supports fully replicated BES (BlackBerry Enterprise Server availability) in both environments for maximum mobility and maintained. Forum Oilfield Services, Houston, Texas, currently has 600 employees Ceryx Hosted Exchange solution, with nearly 100 users of mobile phones.

Beware of “bargains”

Unfortunately, the market welcomed the Exchange that providers are not as many on delivering a reliable and robust, as they sell the direction of their low cost and high volume of relevant mailboxes. Vendors that offer 3 or 4 GB mailboxes ignore what is meant generally that the mailboxes are not broadcast in this format very well and are vulnerable to data loss. The fact that corruption is not only to the user in question is limited, but all users are able to save the impact, perhaps even the entire server.

These providers may offer mailboxes that size at an affordable price if they compromise on some other costs – dedicated servers, SANs, anti-virus solutions or a fully redundant architecture. Of course, the effort is greater loss of productivity and the possibility that the results of more than one solution, with the main objective of the meeting of the lowest price possible, which was designed to compete with free solutions on the market, and companies do not deliver the performance and availability.

Ask all potential suppliers for the following:

How do you measure up?

A lost or delayed e-mail can be considered a nuisance or a warning. Purchasing decisions should be fiscally responsible, but often, apparently low-cost solutions can be devastating and costly in the long term.

How does the system measure? With Ceryx as a control to measure the speed, versatility and robustness of the system.
