IBM builds High-Performance SAN to Deliver Managed Backup Services

IBM Business Continuity and Resiliency Services (BCRS) team helps clients protect their mission-critical information and maintain continuous business operations, with help from Cisco MDS solutions and Cisco Services.

Business Continuance describes the processes, procedures and technology solutions an organization puts in place to ensure that essential business functions can continue after a disruption. A good business continuance plan consists of risk analysis, contingency planning, and a disaster recovery plan that includes technology solutions to address recovery and data protection needs of business-critical applications. The cost of outage, whether due to natural disasters, power failure, or malicious acts, is usually in tens of thousands of dollars to Millions, depending upon the nature of the business.
IBM
Recently, IBM BCRS in the United Kingdom engaged with a new operating entity of a world-leading financial services organization, to ensure that the organization’s business data was backed up and preserved in the event of a disruption. The client chose IBM Managed Backup offerings. To support the customer requirements, IBM had to build the SAN infrastructure from the ground up, it teamed with Cisco to create and implement a dedicated, large-scale, best-of-class enterprise SAN solution.

The client’s primary need was to establish a backup infrastructure and processes for maximum resiliency.  The client organization has more than a petabyte of data now and expects storage needs to increase by 500 TB year over year. Hence scalability was a huge concern.  The SAN switching core must be able to easily accommodate growth and maintain high performance.
Business Challenge faced by the client is summarized here
  • Deliver high-quality managed backup services for new operating entity of world-leading client
  • Build in high scalability to meet future demands
  • Deploy new large-scale SAN on time
Network Solution
The new SAN design spanned across two locations connect by DWDM links ( see network diagram below).  For the SAN core, IBM chose Cisco MDS 9513 Multilayer Directors—high-performance, multi-protocol, director-class. For edge switches, IBM chose Cisco MDS 9148 Multilayer Fabric Switches. This high-performance, flexible platforms deliver the industry’s highest port density and lowest power consumption available in a compact one rack-unit (1RU) chassis form factor.
The two locations are connected using 4x8-Gbps dense wavelength division multiplexing (DWDM) links. Fibre Channel traffic is extended over those links. Edge switches are connected to the core with 4x8-Gbps Fibre Channel links.  For backup, the IBM TS3500 Tape Library connects directly to the Cisco MDS 9513 switches using 8-Gbps links. IBM Tivoli Storage Manager provides backup services, and the servers connect to the fabrics through Cisco MDS 9148 switches.
IBM_network
Total storage capacity for the production environment is approximately 875 TB, while capacity in the backup environment is 750 TB. This architecture now provides comprehensive backup capabilities across sites for maximum resiliency.
The whole infrastructure is managed by Cisco Prime Data Center Network Manager (DCNM).  The customer liked Cisco DCNM because it’s a best-of-breed solution and easy to learn.  According to Jamie Levett, Lead Infrastructure Architect “This feature is critical because the IBM BRCS SAN management team is centralized offshore, and it needed to be able to quickly learn and manage the new SAN.”
Business Results
  • Implemented large-scale SAN that meets IBM client’s bandwidth and availability requirements
  • Achieved smooth, on-time implementation
  • Gained outstanding education for engineers and offshore SAN management and operations teams
“Implementation ran smoothly with outstanding support from Cisco. Besides building and configuring the deployment, Cisco delivered superb education to our engineering, SAN management, and operations teams. Together, IBM and Cisco operated as one team to get the right solution implemented on time.”  Jamie Levett Lead Infrastructure Architect, IBM Business Continuity and Resilience Services. Levett notes that the education and knowledge transfer gained from this implementation will be invaluable in helping secure future client engagements.

Summary
Cisco along with IBM provides products and technologies that help ensure high availability, reliability, and security for building scalable storage networks and allow optimized distance extension over regional, metro, and long-distance optical and IP networks.
Cisco has made a strong investment in the SAN product portfolio to meet performance, reliability, scalability, and flexibility requirements for the decade ahead.  Cisco, last year introduced the first two members of its 16G fibre channel family- Cisco MDS 9710 Multilayer Director and MDS 9250i MultiServices Switch. Cisco  also provides a complete end-to-end unified data center fabric  that is powered by the same NX-OS operating system across its award-winning product line–Cisco Nexus® for data center Ethernet networking, Cisco MDS for storage networking, and Cisco UCS® for compute.

Green Data Center Power Management Solutions - RahiSystems





In recent times, with environmental issues garnering attention, data centers are attempting to go greener by using renewable resources and reducing the amount of energy used by them. Operators have some of the most innovative data center power management solution to tackle the issues. While for some of the big data centers that have global presence, tackling environmental issues are a part of their business models. It is vital for the perception of their brand as they are looked upon as people doing their utmost to save the environment. In many cases, being green is looked upon as a necessity than as a major selling point.

Why is a Green Solution Necessary?

It is natural that the data demands grow rapidly. This is perhaps one of the main reasons why data storage green solutions have become a necessity. It accounts for 0.3% of the total gas emissions. However, concepts like cloud computing have increased the need to store these data on servers. Some of the latest innovations in green data center management solutions are:

Renewable Energy Resources

Data centers cannot avoid consuming the amount of energy they usually consume despite of all the energy efficient measures taken. Servers consume a great amount of energy and hence, operators prefer using renewable resources of energy. While some large organizations source their own renewable energy, others have partnerships with renewable energy suppliers. It is rumoured that one of the largest data center company has a building dedicated towards solar power next to their North Carolina center so that the center is sustainable and self-sufficient in energy consumption. Another company of global recognition has a hydroelectric dam near its center located in Sweden to fulfill its energy requirements and a little more than that. 

Cooling Techniques

One of the biggest challenges faced by data centers is cooling their centers efficiently. Traditional methods like chillers, refrigerator units, etc. consume tremendous amount of energy apart from the core IT equipments. This spells a lot on the economy as well as the environment. Therefore, operators are looking and opting for energy efficient ways for cooling solutions. Some organizations are building their centers near the Arctic Circle so that they can keep their center cool using the atmospheric air. Another method is to pump recycled water through the entire center in order to dissipate the heat. Some of them have taken the local sustainable water source such as sea water or canal water and purified them to the level that is needed for cooling purposes. 

Recycling Energy

While there is energy efficient ways to keep the data center cool, there is a lot of interest in the amount of heat generated. Studies are being conducted on recycling the heat for warming the surrounding buildings. Although at present, the heat is used to warm the buildings within the campus, in time, mini-server farms could be installed in homes around the locality. However, operators must find a suitable solution to tackle the security and safety issues.
As the demand for data center power management solutions continue to increase by leaps and bounds, the pressure is mounting on all sides for cleaner, greener and safer environment for peaceful man and nature co-existence.

Structured Cabling: A Necessity


Computers- once upon a time a luxury, have now become a necessity- whether it is an organization, a house or even a grocery shop. It is important for any business to have computer and a good online presence for running successful and smooth business. For business establishments and organizations installing computers with the latest technological features like a good broadband with high speed, VoIP, uninterrupted connectivity are the best solutions for competing with other companies and also to maintain the mandatory healthy standards. This can be possible only if organizations have up-to-date and effective infrastructure necessary for good networking. Some of the best communications designs and strategies work well with structured cabling systems. They are efficient and durable helping your business stay connected and grow faster throughout the world.

Communication can be made through various ways and thanks to technological advancements, effective communication is possible through voice as well as data. Irrespective of the communication mode, network cables are the right solution for solving problems like disturbance in work flow, irregular transmissions and other such organizational problems. Although there are different kinds of networking solutions available, structured cabling is one of the most effective ones with respect to efficiency, reliability, speed as well as cost. It also lets you stay abreast with the latest technological advancements. Some of the biggest advantages of having a structured networking system are as enlisted below:

#1. Flexibility
Structured cabling can adapt itself to almost every kind of infrastructure. It is flexible in the sense that it can be removed easily and re-installed during department relocations and shift of office premises. During changes in the networking pattern, structured cabling adapts itself and adjusts without causing any disturbance in the work flow. It works well for both data as well as voice cables.

#2. Productivity
Data can be transferred and recovered at great speed. This spells a lot on the overall productivity and also saves the organization a lot of time and money.

#3. Installation
Whether you are running a large scale organization or a small scale business, whether your office is in a residential complex, high-rise building, compact office or even an industrial belt, installing a structured cabling system is the best solution owing to its ease of installation.

Things to look for in a KVM (Keyboard, Video & Mouse) Switches

http://www.rahisystems.com
IT professionals spending any significant time in server rooms know the importance of good quality keyboard/video/mouse switches. Plagued with a poor performing KVM switch, even mundane tasks — such as cleanly rebooting systems, confirming successful backup operations, downloading and installing OS updates, and completing general troubleshooting routines — become needlessly complicated.
 
Whenever you buy a new KVM switch, you want to make sure it meets your requirements. Review this list to avoid common errors many rookies or budget-minded organizations suffer when selecting a unit too quickly or without performing the necessary homework.

1: Proper operation
Little in IT is as frustrating as not being able to properly view a critical system or connect using a standard keyboard or mouse, especially as the issue seems to arise at the most crucial times (an email server is down, the Internet has failed, hundreds of users are affected, etc.). When you’re combating a stressful failure or outage, that’s no time to have to fumble around with a flaky KVM.
Perform some due diligence. Whenever you think you’ve found the perfect KVM, search Internet forums and read Amazon, Newegg, and other reviews to learn what others’ experiences have been using the same model. If feedback is positive, you’re good to go. But if proper operation in the real world proves troublesome, keep searching.

2: Compatibility
KVMs often work with most operating systems, but occasionally glitches arise. Review a model’s specifications to make sure it’s compatible with the operating systems it must support. If you don’t, you’ll have to box everything back up, request an RMA, and send it back.

3: Required connections
I’ve seen seasoned engineers purchase new KVMs that support only DVI video connections or only PS/2 peripherals, then discover the servers all have USB- or VGA-only connections. In other cases, engineers assume that the model they’re buying provides KVM over IP support, when it doesn’t.
Don’t order a KVM switch haphazardly. Confirm that models support the connections in place, which may require a quick-and-dirty audit of current equipment prior to ordering, especially when equipment from multiple locations is being combined in a single site for the first time.

4: Port expansion
Shortsighted administrators often purchase eight-port KVM switches when they need to support eight servers. Whenever possible, purchase KVM switches with additional capacity. Unforeseen but reasonable decisions to add a VOIP system, new database platform, HVAC- or alarm-controlling servers, and other devices instantly place you at a deficit. Too often, organizations end up with more systems than ports; if possible, purchase KVM switches with 20% to 25% extra ports.

5: Onscreen display
Onscreen displays (OSD) and menus are kind of like rear-window defrosters — you don’t miss them until you don’t have them. They provide visual indications of which systems are online or connected, making it easier to configure settings and switch between systems. If you’re accustomed to working with GUI assistance, select a model that supports OSD. Also consider OSD-enabled KVM switches if you have to switch frequently between numerous systems, as OSD will make you more efficient.

6: Mount options
Desktop KVMs work well within many organizations, but they don’t work well when migrated to server racks. In businesses experiencing growth but working without a current server room or even half-rack, look for KVM switches that can be converted to rack mount, should the need arise. Or start with a standard rack mount unit. Select desktop models only if you’re confident the unit will never end up servicing systems mounted in a professional rack or cabinet.

7: Electrical power
KVM switches with their own power supply work more consistently, in my experience, than do those that draw their electrical supply from the systems they connect to. Even many budget-priced KVM switches include optional power supply connections but don’t ship with a standalone power adapter. Always check to see whether a power adapter is included with, or supported by, the unit you select. If no power supply is included, visit a nearby Radio Shack or electronics store to purchase the missing component, after assuring its compatibility.

8: Sufficient cable length
More than once, I’ve seen six-foot KVM cables prove too short when wound through cable management infrastructure. As part of a pre-purchase audit, measure the distances the KVM’s cables must cover. Ensure that included cables, or those you purchase separately, are long enough to span the required distances. It sounds academic, but KVM cables are expensive, even when purchased in bulk, and they are painful to have to rerun in server cabinets after discovering the just-purchased items are too short.

9: Reset button
Occasionally, KVM memory becomes corrupted. Since KVMs frequently receive power not only from a standalone power adapter but also from the systems the KVM switch is connected to, it can prove difficult to clear a corrupted KVM switch’s electronics. No one should have to climb behind a server rack to physically disconnect four, eight, or even 16 systems just to clear a frozen KVM. Look for systems that have a simple reset button.

10: Audio support
While less common, some environments require that system audio be available from the systems the KVM Controls. Of course, not all KVM switches support audio. Review a specific model’s individual specifications to confirm that it will support audio. Otherwise, you could find yourself stuck with convoluted workarounds resulting in a cacophony of noise. Prevent headaches. KVM switches can be very unforgiving. Perform your homework up front.

Types of KVM Switches





RahiSystems.Com



USB: A switch that uses USB cables for keyboard and mouse connections. Some USB switches will also allow PS/2 connections and some will allow sharing of other USB devices such as printers. Other things to look for in a USB switch include ability to share audio and wireless keyboard/mouse connectivity. Also remember to note which USB specification the switch supports.


DVI (Digital Visual Interface) – A switch for use with a DVI compatible monitor or monitors. While the standard monitor connection is typically VGA, DVI monitors are becoming more popular and widely available. DVI switches often have increased resolution capabilities

HDMI (High-Definition Multimedia Interface) – A new emerging market for KVMs includes HDMI ready switches. These switches are used for connecting HDMI compatible displays. This is especially useful in the audio/visual production field, as well as medical professions where high resolution displays are required. Another use for an HDMI KVM switch is for home theatre setups, where a tower and laptop might share a large High-Definition television.

DisplayPort – Another new market is for switches which support DisplayPort technology. With monitor manufacturers moving away from VGA and DVI-I interface; availability will become more important.

Multi-Display – A multi-display switch will allow for extended desktops across two or more displays. Displays can be VGA, DVI, HDMI, DisplayPort and in some cases mixed input. The number of monitors can range from two to four and higher for specialty applications.

Rack Consoles – Integrated display, keyboard and mouse/touchpad units for use in server racks, rack consoles will also often include an integrated switch. These space-saving monitor drawers provide convenient access to servers right at the server cabinet. One important consideration is the type of mounting rails used for the LCD drawer. Not all rails will work in all server racks.

KVM-over-IP – IP switches use a browser to securely access servers/computers over the internet or Local Area Network. IP KVMs are a good replacement for software based remote access packages such as RDP and VNC. Depending on the particular model, benefits of a hardware remote access solution include the ability to cold boot equipment, BIOS level access, port level user profiles, and robust logging.

Multi-User – A multi-user switch will allow simultaneous access to the switch by more than one user from multiple locations. This is accomplished via extension, Over-IP access or a combination of both. Multi-user switches are an excellent choice for enterprise applications where cross-platform switching is needed by multiple team members.
