Data Centers are heart for any organization; Data Centers are the one which houses the majority of Servers farms, Switches, routers, security solutions, SANs and much more. These days we were asked to develop the Security Polices and Procedures for our Data Centre which I am going to share in upcoming blogs.
In this particular part of my article I will try to focus on the Data Center physical security policy and procedures.
1. Overview
Security for the Data Center is the responsibility of all departments that are sharing the data center space. ITKE* is responsible for the administration of this policy. The following are the general requirements and policies to access to this sensitive area. Failure to follow the guidelines set forth in this document is grounds for termination of agreements and potential legal action.
Customer MUST NOT, except as otherwise agreed by ITKE*,
-
- Place any computer hardware or other equipment in the Licensed Area
- Store any other combustible materials of any kind in the Licensed Area; and
- Bring any “Prohibited Materials” (as defined below) into the Data Centre. Prohibited Materials shall include, but NOT limited to, the following and any similar items:
-
- Food, drink, illegal drugs and other intoxicants
- Tobacco products
- Explosives and weapons
- Hazardous materials
- Electro-magnetic devices, which could unreasonably interfere with computer and telecommunications equipment
- Radioactive materials
- Photographic or recording equipment of any kind
- Any other items deemed inappropriate at ITKE*’s sole discretion.
2. Primary Guidelines
The “Data Center” is a restricted area requiring a much greater level of control than normal spaces. Only those individuals who are authorized to do so by the ITKE* may enter this area. Access privileges will only be granted to individuals who have business need to be in the data center.
All departmental staff sharing the Data Center will familiarize themselves thoroughly with this document. Any questions regarding policies and procedures should be addressed to ITKE*.
The only exception allowed to the Data Center Security Policies and Practices is temporary suspension of these rules if it becomes necessary to provide emergency access.
In upcoming article I will try to focus on levels of access can be provided to the Data Centers.
*ITKE is used just as reference which can be replaced by your organization or department name.

A review for CCDA 640-864 Official Cert Guide
An Excellent title not only serves to pass the CCDA 640-864 exam but also a great reference asset just simply because it covers each and every topic in great detail. As other Cisco Press titles this book too follows the same style by stating pit with the “Do I Know This Already Quiz” which give you an idea about strengths or weaknesses in particular topic.
Especially when CCDA exam is much more about understanding the topics from Design perspective, this title serves you to understand the topics in great detail in much simpler and easy to understand language. The greatest thing about this the title CCDA Official Cert Guide is the way each chapter is presented with very detailed out line of “Foundation Topics” in very organized manner. And this title covers the design of Cisco Internetwork Infrastructure from the General Network Design, LAN and WAN Design, Wireless Networks, Routing Protocols Design to Security, Voice and video design.
One more interesting fact I notices is the title CCDA Official Cert Guide covers all the new advancements in Network Technologies, it covers topics such as Cisco Data Center 3.0 Architecture framework, virtualization technologies implied by Cisco Systems on various Cisco devices.
With this title CCDA Official Cert Guide Cisco Systems came out with a new testing Engine for practice exam. This title comes with a CD which contains the Pearson Cert Practice Engine which allows you to take practice exams as well as the “Do I know This Already?” Quiz. The Pearson Cert Practice Engine is great, it does have some practice questions it would have been if Cisco Press enhanced the test Engine by adding even the practice question which are available only in book at the end of each chapter.

Overall this title is a great asset and for sure a helping guide for those who are planning to pass Cisco CCDA 640-864 exam. I rate this of title 4 out of 5 stars.

While designing an IP Telephone Network we need to be aware of few important things such as bandwidth requirements, delay and QOS of schemes. The most important thing while designing an ITP network is the proper capacity planning. Within capacity planning, bandwidth calculation is an important factor to be considered.
By using Cisco Voice Codec Bandwidth Calculator we can determine the bandwidth used by different codec with various voice protocols over different media.
Really a cool tool which eases the task of Network Designers, the only condition to make use of Voice Codec Bandwidth Calculator is you need to have a valid CCO login id.

While checking the daily logs in one our Cisco Catalyst 6500 Series Switch I figured out following error “socket SO_UDPCHECKSUM option setting failed error”. For the past five years this Cisco Catalyst Switch worked well without any problems, the sudden emergence of this error “socket SO_UDPCHECKSUM option setting failed error” forced me to think what were the last modifications? I figured out the last thing what we did was configurations of few IP SLA’s. When I checked Cisco web site it was confirmed the error was generated due to the configuration of IP SLA. We are currently using the IOS Version 12.2(33) SXH8b. This IOS version has a bug.

According to Cisco Systems the error “socket SO_UDPCHECKSUM option setting failed error” has no negative impact on the Cisco Catalyst 6500 series Switch. The work around is to remove IP SLA configuration or upgrade the IOS version.
This error appeared for the first time in the IOS version 12.2(33)SXI1 and this bug is fixed in following IOS versions
12.2(32.8.11)SX291
12.2(32.8.11)XJC273.11
12.2(33.2.4)SXI
12.2(32.8.1)YCA273.15
12.2(33)SXI3
12.2(32.8.15)YCA273.10
12.2(33)SXI4
15.0(1)SY
So if you happen to see the following error in your Cisco Catalyst 6500 Series switch don’t panic, the bug has least impact on device the only work around is either to remove the IP SLA or to upgrade the IOS of the device.

cold aisle
These days we thinking of establishing a DR site for our organization, I went through various solutions starting from cloud computing to renting a rack space. But Cisco’s Containerized Data Center emerged to be an interesting option
What is Cisco Containerized Data Center (CDC)?
Basically the Cisco Containerized Data Center is a 40-foot container, which is capable of housing up to 16 cabinets of 44 RU. Cisco has adopted chilled water cooling system that uses cabinet-level airflow containment rather than a hot aisle/cold aisle design. The Cisco Containerized Data Center comes with an access door at end of the container basically this modular approach allows the containers to either be stacked or deployed alongside one another.

Following are the features of Cisco Containerized Data Center (CDC)
- Timely response to dynamic data center needs: Significantly reduces deployment time for new and existing data center initiatives
- Flexibility: Can be configured to meet customer-unique business needs
- Serviceability: Designed for efficient serviceability and to meet power and cooling requirements
- Optimization: Can be placed in either indoor or outdoor environments with the flexibility to deliver the Cisco CDC to multiple locations
- Cisco CDC Management System (CDCMS): Integrates multiple components to help ensure the safe and efficient operation of Cisco’s modular data centers
A good innovative from Cisco Systems, which definitely provides a fast solution, flexible to way to expand, complement, or even replace traditional fixed, “brick-and-mortar” data centers And even for those who are thinking establishing a DR site

Cisco Nexus 7000 Series
When it comes to Cisco Embedded Event Manager (EEM) on Cisco Nexus platform it slightly differs from the Cisco Catalyst 6500 Switch platform. In Cisco Nexus platform each line card module runs its own instance of EEM subsystem (an EEM Client), which results in handling of EEM events locally by the respective line card module. This in turn frees the supervisor Engine resources from managing the EEM event publication and executing policies across the chassis.

One more great advantage of distributed architecture is it further improves the latency of time taken to invoke the EEM policy execution.
