Next Gen Data Center Forum Circa 2004-2006
With the data center firmly established as the information hub of the modern business, it is vital that IT managers and users keep up on the latest news in technological research and networking developments. The NDCF met this crucial need with its in-depth news and analysis, product reviews, discussion forums, newsletters, and training programs.
This was the NDCF's website for a number of years until it merged with two other sites to become Byte and Switch.
Content is from the site's 2004-2005 archived pages offering just a glimpse of what this site offered its visitors.
The Next-gen Data Center Forum is a Website designed specifically for the needs of those IT managers who are responsible for data centers. But the NDCF is much more than just a source for news, research, and expert advice. It is also a Forum in the truest sense of the word, an online meeting place where IT managers can discuss the latest data center issues. This is where IT managers come to share data center knowledge and best practice.
Data Center Infrastructure Concerns 06.21.04
Q. Does anyone have any concerns on the infrastructure needs of the data center? Specifically, cabinet and rack requirements? Are there good solutions available? Or do changes need to be made for this type of product?
A. In terms of infrastructure concerns, that is about the highest priority on most data center managers' agendas today- particularly cooling and power. With the proliferation of smaller and smaller equipment, and the surging use of storage racks, placing a lot of heat-producing devices in a very small footprint and close proximity [means that] cooling and power problems abound. As do the solutions being offered.
We have a full track on this at our upcoming [October] conference in Atlanta. We call the track "Facilities." This track focuses on such things as cooling, power, fire suppression, physical security, data center design, and raised flooring.

Handling an FTP Session During a Failover 03.18.04
Q. How do you handle an FTP session in progress during a link failover to maintain its connected sockets?
A. The art of building reliable network and computing infrastructures is deep and complex. Generally, networks are architected to contain multiple redundant paths between any data source and any data sink. Those redundant paths may exist at multiple layers of the OSI protocol stack, with each implementation choice protecting against a certain class of failures and introducing its own set of complexities.
In your question, you ask specifically about failure of a network link. There are many ways to protect against this type of failure. Between two different network devices (switches or routers, for instance), there may be Layer 1 alternatives such as link aggregation, Layer 2 alternatives such as spanning tree (with or without the various rapid reconvergence variants), or Layer 3 alternatives such as various routing protocols (OSPF, BGP, etc.). Between a host and the network, options typically include Layer 1 options such as link aggregation or Layer 3 options such as providing a host with dual network interfaces.
Each of these various alternatives is agnostic with respect to application-layer protocols such as FTP; they work equally well with HTTP, SMTP, etc.

Backup Bottleneck 03.16.04
Q. What do you see as being the next major bottleneck in the data center?
A. As far as the next major bottleneck in the data center is concerned, my view is that the volume of data that needs to be backed up for disaster recovery purposes is growing faster than the bandwidth that is economically available to enterprises to move off-site

The software side of routers has always been important. Now it's becoming even more so, for two reasons. First, the emergence of new services, such as MPLS-based VPNs, is putting routing protocols like BGP under a lot of pressure. Second, scaleability and reliability (including the ability to execute hitless software upgrades) has become a critical for carriers moving to converged, packet-based backbones. This webinar identifies issues and reviews how vendors are addressing them.

The telecom industry is going through a fundamental change from focusing on building the next-generation network (NGN) to working out how to use that infrastructure to enable next-generation services (NGS). This marks a dramatic shift away from thinking of services in terms of network connectivity and towards thinking of services as applications, or bundles of applications, provided over whatever access infrastructure is most appropriate at the time. We analyze this critical trend.

Blade Center Solutions 03.14.05
Question: I have a blade center and a blade center cabinet. We plan to populate the cabinet with six blade centers -- using every rackmount unit. I'm looking for a solution that allows me to have my horizontal crossconnect (fiber and copper) installed in the cabinet without using rack space (there is non left). I need something that is on the back of the cabinet, but sticks out away from the blade centers. I don't want to run patch cables from each blade center to the network and SAN. Is this possible? I've looked everywhere.
Answer: I contacted our partner Dave Kohler, CEO of LOOK Communications in Columbus, Ohio, and he tells me the following:
There are two ways to accomplish this. First, is to have deeper cabinets that have front and rear rails. The depth makes it so that the infrastructure does not interfere with the server management hardware. The infrastructure is then placed on the rear rails at the top of the cabinet. The increased depth should be approximately 12 inches for the patch panels to patch properly.
Second, if the cabinets are already procured or existing, the use of raised floor enclosures enables connectivity. These enclosures are placed in the access floor at the rear of the server cabinet. Because of the high density of the enclosure, we generally utilize one enclosure per two server cabinets. A piece of innerduct approximately 2 to 3 feet long is placed from the enclosure to the server cabinet bottom rear. Optical fiber or category copper cabling with a properly listed jacket is then installed from the network and SAN switch edges to the enclosure. This does away with the use of long and custom patch cables. All connections are then accessible at the server cabinet location. The enclosures come in different depths depending on the raise of the access floor. For example, an 8-inch access floor enclosure can accommodate 192 optical fiber and/or copper connections. The cable media can be mixed in the enclosure if the network is category copper and the SAN is optical fiber.

Management Structure 03.14.05
Question: I'm looking for best-practice information with regard to the organizational management structure of a large data center (120,000 square feet). Any data describing roles, responsibility, and reporting relationships would be appreciated.
Answer: This can best be answered by understanding the IT products and services that will be provided by the data center. There are several feasible operating models and a few questions should be addressed to give you the practical answer. For example:
What functional areas and systems will be installed in the data center?
Will the silos include telephony, mainframe, LINUX, UNIX, Windows, NAS, SAN, networking, security, middleware, and facilities infrastructure, etc?
Are you following a functional silo model or are you providing products and services in accordance with the IT Infrastructure Library (ITIL) IT Service Management framework?
How does the rest of the organization support the data center? Will the data center provide 24-hour or lights-out support?
What is the data center's relationship to other support areas?
The answers to these questions will provide the basis for your solution.
Greenwich Technology Partners is a definite proponent of ensuring end-to-end services for the business and recommends alignment in that manner. Your organizational structure and total staffing will depend on the skill sets of your personnel and their abilities in multiple functional areas. There are many reasonable options and they could probably all work.
However, you should ensure that there is strong documentation of roles, responsibilities, processes, procedures, and working instructions. You should also ensure clear lines of operational direction and control. Reasonable job descriptions should be tied directly to the responsibilities and the purview for each position. I would check the Web for plenty of examples.
- Scott Miller, Senior Network Engineer, Greenwich Technology Partners
Fiber or Copper?
Q. Are fiber optics the standard media in data centers or does copper still have a large market share?
A. Both copper and optical share data center market share. I would guess that copper is still more dominant...
