Since Exchange 2010 includes the following server roles:

Server mailboxes on this server hosts the mailboxes and public folders. · Client Access server in the server hosted client protocol, such as POP3, IMAP4, HTTPS, mobile Outlook, service availability and service auto-discovery. · Server Unified Messaging This server connects the internal PBX and Exchange 2010. · Hub Transport server is routing mail routes the internally Exchange. · Edge Transport server is routing mail, which is usually placed at the boundary of the topology and routes the incoming and outgoing mail in your organization Exchange.

Standard design requires a Client Access server farm with load balancing for high availability and performance solutions. For Exchange 2010, you can use softovoy Balancing Windows Network Load Balancing (WNLB) but with the following restrictions: · WNLB can not be used in conjunction with database availability groups (DAGs) – functionality allows you to sync mailboxes across multiple sites. Due to performance issues do not recommend running more than 8 Client Access servers balancing WNLB. · WNLB can not detect a denial of service on servers and only works at the level of L3, ie, determines the availability of servers based on IP. That is, if the server responds to IP, but server applications do not work, you want to remove the failed server client access from the pool balance manually. · WNLB configuration errors can lead to degradation of network bandwidth. As WNLB balancing exercises only at the client, with a limited pool of client addresses, for example when using NAT, load balancing between servers, Client Access does not work effectively.

All these problems are eliminates by the use of hardware balancers Brocade ServerIron ADX, which balances the load on the levels of L4-L7, with a maximum capacity per chassis up to 70Gbps, allow you to choose from a variety of mechanisms to balance and carry out constant monitoring of servers from the IP-availability and load SNMP and ending with an extended Health check up to check the response given on the application.

The joint solution of Brocade and Microsoft have passed laboratory testing in the Microsoft Enterprise Engineering Center (EEC) in the Microsoft headquarters in Redmond.

In this scheme, ServerIron ADX provides:

* Save sessions. Client to connect to one of the servers continues to work with him only within the session.

* Rules of switching content (Content Switching Rules). Through support for switching at the level of L7, ADX can make decisions on balancing traffic based on data about the URL, cookes, or ID SSL-session

* SSL-proxy – the maintenance of a secure tunnel between client and server with the possibility of balancing at the application level

Monitoring the north to control their availability and willingness to process requests.

Japan's Kanebo new company PLA fiber

In recent years, many publications reported that the foreign development of polylactic acid (PLA) polymers for information. Japan’s Kanebo Goshem Ltd. Is a leading producer of PLA fiber one of the manufacturers. Back in 1997, the company began production of the PLA fiber LACTRON trademarks and February 1998 in the Nagano Winter Olympic Committee, the display of the PLA fibers with PLA fiber or blended with natural fibers made of clothes.

1, LACTRON Overview

LACTRON is made of corn starch and lactic acid production of biodegradable synthetic fiber. Which does not use oil and other chemical raw materials, it would not pollute the environment, because when its use after abandonment, the soil and micro-organisms in sea water can be partitioned into carbon dioxide and water. In addition, its cycle of reproduction and a shorter, less than a year, and it through photosynthesis, the reduction of carbon dioxide in air has a great influence.

2, LACTRON the main features of

A new type of synthetic fiber non-petrochemical raw materials; entirely natural cycle of pollution and ecological fiber; with the basic characteristics of synthetic and processing performance; with exquisite silk-like feel and luster.

3, LACTRON Products

]]>

In the currently developed biodegradable fibers, LACTRON high melting point, it can be processed into multifilament, monofilament, staple fiber and spunbond fibers and other fibers.

  4, LACTRON of fiber properties

In the melt spinning and drawing, you can control the fiber extensive strength and elongation. So LACTR with synthetic fibers such as nylon and polyester fibers is almost the same characteristics.

  5, LACTRON use

As LACTRON with excellent features, it is expected to dress in industrial materials and the general areas of development and application of widely. LACTRON can be developed into a variety of products similar to conventional synthetic forms such as lines, fabrics, knitwear, non-woven fabrics, and spunbond products. Kanebo has the LACTRON as a new fiber materials, extensive opening of the apparel and non-apparel uses.

  6, LACTRON biodegradability

    When the public on the composting plant or plant when, LACTRON thoroughly and safely broken down into carbon dioxide and water. Even when it is burned, the combustion gases do not dioxide, nitrogen oxides and few, and burning calories is about other materials such as polyethylene and polypropylene one-third, it can be burned without any danger to freedom.

Kanebo company has been buried by soil, sea water and activated sludge treatment methods such as biological degradation of being treated LACTRON fabric strength and weight to monitor the changes. Results found:

Buried in soil tests no major changes in fabric weight. However, in two years, almost total loss of fabric strength, in fact, has been decomposed.

In sea water immersion test, the change trend and similar soil burial test.

In the activated sludge test, the use of bacteria and micro-biodegradable materials, in 1-2 months, almost complete loss of fabric strength.

In accordance with the OWS controlled composting biodegradation test method tests done, LACTRON fabric show faster than cellulose powder is very good degradation.

In contrast, conventional fiber degradation has the following characteristics:

In any conditions, polyester fiber to keep the original shape and features, without being decomposed.

In activated sludge, containing fibers such as cotton and rayon, compost faster speed than LACTRON.

      Thus, LACTRON fiber biodegradability Although not as natural fiber, but so much better than conventional polyester synthetic fiber.
