How ANALYSYS Survived Snowmageddon 2010

February 22, 2010 Leave a comment

What you can do to ensure business continues in the face of a disruption to business as usual.

I’m so proud of my team at ANALYSYS.  We didn’t skip a beat during Snowmageddon 2010, and quite frankly, we shouldn’t have.  There’s a couple of reasons why.  First, we are expanding from a regional Washington-Baltimore (or Baltimore-Washington depending upon where you hail from) footprint into a national one.  We have national and multinational clients on the books that expect service continuity from us.  Second, the Computing as a Service (CaaS or Cloud Computing) and data center technologies we offer involve a strong resiliency message, and a blizzard of historic proportion is the perfect example of a disaster we say our solutions protect against.  Therefore, it would be hypocrisy if our team wasn’t able to get work done.  Third, we prepared in advance.  Long ago, we developed plans to accommodate unplanned circumstances such as power loss, theft, vandalism, and of course natural disasters… and we keep them up to date.

Now seems to be a perfect time to share some of these practices which made last week a success.  In my opinion, it’s a great case study on what any small business out there should be doing to protect themselves.  To put things in perspective, remember that this storm was so bad that nobody could get into work.  This meant all of us had to work from home and still meet our goal of transparency in the experience ANALYSYS clients received.

Secure Remote Access - Every day ANALYSYS is at work, we are operating remotely.  That’s right, when we are

ANALYSYS Data Center Operations in Baltimore

sitting at our desk on a normal day, the data we work with exists somewhere else – not in our office.  So, from a computing standpoint, even though our team worked from home, they didn’t need to change anything.  Fast?  There’s a local server (some file sharing, print, and Active Directory) in our office plus fast internet access to accommodate the demand and keep things speedy.  Secure?  From a physical standpoint, the data center in which we placed our systems is incredibly secure (SAS 70 Type II certified), more secure than things would ever be in our office.  From a networking standpoint, we use the same firewalls and security practices we would use if our systems were connected to the internet in our office.  Reliable?  There’s redundant internet access from our office in case there’s an outage, the data center has a multi-million dollar investment in battery, HVAC, generator technology.

What steps can small business DIYers take to emulate this type of solution?

  • Partner with a data center and move your systems off-site.  Go take a tour of the facility prior to signing up.  Yes, that means doing business with someone local.  You don’t want to hop on a plane every time you need to your servers, nor do you want to pay a data center help desk technician $200 per hour every time you need hands on-site.
  • Install connectivity, such as a point-to-point T1.  If your needs are modest you might also get by with a Verizon FIOS or Comcast connection.  Try to ensure you have at least two in case one fails.  Internet connectivity is your weakest link in the chain between users and their data.
  • Implement the routing.  Check out SonicWALL’s SSL-VPN product.  It’s a simple, affordable solution for small businesses that want to do remote access themselves.
  • If you want to institute desktop virtualization, take a look at Microsoft’s Small Business Server Remote Web Workplace, or for a slightly more robust solution, check out Citrix XenDesktop.

Voice Over IP Telephony (VOIP) – Much of the public believes that VOIP phone systems will operate anywhere.  That’s not necessarily the full truth.  VOIP by its very definition means a phone system that operates over an IP (computer) network.  However, depending upon the make/model of the phone system these may or may not offer functionality beyond one network segment (one physical location).  Furthermore, the way VOIP systems define the anywhere, or remote, capability, critically depends upon how it’s set up.  As for us, our phones work anywhere we take them, in the office or out of the office.  In order for someone to work from home, they simply pick up their phone, take it home, and plug it in to a connection with internet access.  As a backup, we can also have our phone system forward calls to different extensions, and even home phone numbers if necessary.

So, what do we look for in a VOIP solution?

  • Before you begin your research or call anyone, define your expectations clearly.  Unlike computer networks and remote access VOIP requires involvement from a blend of service providers and equipment that is exceedingly complex and perpetually in a process of innovation.  Once you have your goals outlined, consider retaining the assistance of a qualified telephone system installer.
  • Explore redundancy thoroughly.  Many phone lines are digital these days.  This adds a tremendous amount of potential but also adds complexity, where something as simple as a power outage or a cut wire to a box somewhere in the closet could mean an entire system outage.  Implement a second technology as a backup plan and ensure your systems automatically fail over.  Technologies to look at combining are traditional copper (aka Plain Old Telephone Service or POTS), SIP trunking, shared data/voice over a T1, cellular backup, and ISDN.
  • Save money!  Companies that have not changed their phone systems in more than three years, may be able to reduce their recurring costs of phone service by switching to newer technology.  As opposed to contacting the telephone companies themselves, consider retaining the services of a consultant that specializes in this area.  You’ll have an expert in your corner who will advocate before the service providers that want your business.
  • Monitor your systems for outages.  As opposed to waiting for someone on your team, or worse, a customer, to note a service problem, get out in front of a service outage with tools that send you an email, text, page, or telephone call when there’s a problem.  These tools are easy to use and come in the form of software or appliances you can own, or even can be purchased as a service from a third-party.  Ipswitch’s WhatsUp Gold or GFI’s Network Server Monitor are great tools for small businesses.  Solarwinds offers solutions for more demanding environments.

Battery Power & Generator Backup - Nothing is more frustrating than losing work from a momentary power outage.  A longer term outage can be crippling.  For how expensive a power outage can become, not to mention the unplanned impairment to team efficiency, batteries and generators are tremendously low cost and respond to the most frequent unplanned disaster businesses suffer.  So, although battery backup and generator systems didn’t play a role in our response to Snowmageddon, I felt that it was an important detail to include.

  • Protect workstations.  A $40 per seat investment in a workstation battery backup enables our folks to save their work if the power goes out, renders blips irrelevant, and gives the backup generators time to come online.  We use APC BackUPS for this purpose.
  • Protect infrastructure equipment.  Just like momentary coverage for desktops, if you want a fully functional network, you’ll need battery backups for everything else, including firewalls, routers, switches, wireless access points, etc.
  • Install backup generators.  These aren’t expensive, and surprisingly many landlords welcome the improvement if the tenant is willing to contribute the capital.  Within the electrical contracting community, specialists exist who focus on implementing backup generators.  Contact one and have them help with this initiative.
  • Go green.  Do you own your own property?  Great!  While they are installing your backup generator, save on your power bill by engaging your electrical contractor for help with improvements that reduce power consumption.  For a more modest step, consider implementing smart surge suppressors and power saving measures on your network that shut systems down automatically when not in use.  Does the landlord pay the power bill?  Beware – with the cost of energy spiraling upward, many rental agreements are now being renewed net of power costs.  So, how does this relate to backup power?  Remember, if you manage the technology that’s running to keep it to a minimum, that’s less chance you have of an overload.

Well-Defined & Communicated HR Practices – No amount of technology, however elegant, will deliver results if the team is not prepared beforehand.  There are four places in time that we look at.  First, there is strategy which is ongoing and evolutionary.  We want to ensure that our practices are relevant to the business we presently are.  Second, there is planning related to a specific disaster we can forecast.  A snowstorm is definitely a place where we can engage in substantial advance planning.  Third, there is management of the disaster as it happens.  Our goal is to remain prepared, flexing our planning to respond to circumstances which we did not foresee.  And, finally, there is a retrospective on the disaster, as a means of understanding how we can improve.  Substantial content could be devoted to this topic, making it a great opportunity for another post.  For now, I’ll share some of the key areas that helped us through Snowmageddon.

  • Work at home policy.  Define in advance the expectations for work performed from the home.  Who will be authorized to perform work from the home?  If there will be only certain individuals allowed to work from home, how is the approval process applied, and applied fairly?  How are hours worked recorded?  What outputs are expected?  Will the company compensate for any costs such as telephone or internet access?
  • Leave time approval.  How does the decision to implement a liberal leave policy or to close the company impact your employees pay?  Will employees be paid, or will they have the opportunity to use personal leave time?  Equally as important, how will team members register whether they are in or out for the day.  ANALYSYS has a inclement weather line which is updated with our decision to open or have a liberal leave day.  If team members can’t make it in, they register their status on our company intranet prior to the start of the day, making it easy for supervisors to plan accordingly.
  • Points of contact and availability.  It’s easy to create a one size fits all policy that covers what to do in the case of inclement weather, where staff contact their supervisor for instructions.  What happens when members of the management team can’t make it in, but their departments must continue to function efficiently?  Resources must remain flexible and highly communicative.
  • Be proactive!  Let’s imagine in this disaster that HR has a question.  With advisors such as HR consultants and legal counsel and government agencies closed for business, the questions end up going unanswered.

How to Keep the Server Room Cool

How recent improvements in technology present challenges for data center cooling, and what you can do about it.
By Steve Kolbe & Eric Silva

Centralization, and in some cases outsourcing to off-site hosted facilities, is a current trend that continues to unfold in response to the 2008/2009 recession.

This centralization has placed a tremendous focus on the construction of new, more reliable, and more redundant infrastructure than ever before.

Did you catch the operative words there? “New” and “More” … Yes, as this centralization brings a greater amount of technology closer together physically, so too does it centralize the consumption of power … and naturally the generation of heat.

It’s easy to take data center HVAC systems for granted. They operate with little ongoing maintenance and accommodate modest ongoing growth without upgrade or change.

Many existing data center HVAC systems, however, may not incorporate the level of scalability demanded by the times. This is especially true for managers of small and medium-sized business server rooms and private, corporate data centers where the HVAC systems were designed around the narrow scope of a traditional client/server environment.

All of this makes now a good time to proactively look at data center HVAC systems to determine the level of upward mobility available.

Christian Perry of Processor Magazine offers a great story with tips like using temperature monitors strategically positioned throughout the data center to monitor temperatures over time and implementing power management systems that reduce the stress placed upon HVAC systems.

Remember, infrastructure projects like these should take a well-planned and methodical approach. Allow a few months to track and develop metrics before doing anything. This also gives your team ample time to carefully analyze the alternatives, reach out to specialists, and determine the degree of future expandability to build in to any upgrades.

In cases where improvements are being made to systems already in place, Eric Silva of E&S Construction Engineers in Maryland recommends taking an integrated approach.

Simply implementing a patch to fix a heating problem or otherwise making an improvement without proper planning, he says, “will cause the system to compensate in some other area.”

Silva also reminds that engineers who engage regularly in developing HVAC systems in data centers have a broad base of proven expertise they use to routinely develop the most cost effective solution possible.

Silva writes:

Stand-alone solutions are tools that a mechanical engineer would use to create an integrated solution to the problem of a hot spot.

By using these tools, an engineer could rebalance a duct system to eliminate the hot spot, determine whether a hot spot can be allowed in a certain area, or pick a location for a new piece of cooling equipment that could be integrated into a data center’s chilled water system.

It is also possible that the engineer could determine that there are simpler devices that could be used, such as cold-aisle containment, which could be implemented at a lower cost.

Let’s take a look at adding a new duct to bring cooling to a hot spot. We’ll make the assumption that cool air flows through a ducted system (not an open raised floor) for clarity. Duct systems are designed to deliver cool air from the AC unit to the space to satisfy the cooling load. Once the duct system is designed, the fan and motor are selected to move the required amount of cool air through the system. Therefore, ductwork is an integrated system with a limited amount of cool air flowing through it.

If one were to add a new duct to the system, the existing system would become unbalanced. Namely, the existing system would deliver some of its cool air to the new duct, would not supply enough cool air to other areas served by the same duct system, where temperatures would increase.

While it is possible to force more air through the duct system to accommodate additional loads, it would require an increase in fan power, therefore increasing the Power Usage Effectiveness (PUE), and would not provide a directly proportional amount of additional cooling. Even so, the drive for energy and cooling efficiency within the data center has caused modern design to limit the factor of safety (spare capacity) of fans and motors that are selected for AC units and there may not be sufficient power available.

What We Can Learn From The Last Recession

February 1, 2010 Leave a comment

The high technology industry is perpetually in a state of reinvention.  Leaders and decision makers must be willing to embrace this environment in order to be successful.  However, now more than ever is the time to embrace the “change” mentality.

Why?  As decision makers assess ways to right-size their operations, technology, a cost center, is frequently near the top of the list for budget modification.  This spotlight on technology budgets creates pressure on vendors to make their products and services more effective.  Therefore, as opposed to simple cut-backs, savvy leaders and technology professionals demand investments in new processes and technologies to create the savings necessary, while increasing efficiency and performance.

Let’s frame this by looking at the recession of 2001.  Arguably THE most important information technology innovation that occurred during these years related to remote support and connectivity.  The outcome?  Technologies like Voice Over IP (VOIP) telephony substantially reduced the costs associated with calling, particularly overseas.  Remote connectivity software empowered IT support departments to resolve issues without leaving the desk, reducing overhead and resolution times to a fraction of what they previously had been.  These innovations spurred the wide scale adoption of the overseas call center, and although controversial, the result without a doubt achieves the objective of a reduced cost of operating and a sustained level of service to the consumer.

Ask a technology professional today what major innovation of the 2008-2009 recession will be remembered as the most important, and you will get a variety of answers.  Let’s take a brief look at two such innovations with great potential and what these can do for your business.

Cloud Computing - Cloud computing involves the migration of computer networks, into a centralized location, called a data center.  The investment in a centralized infrastructure allows businesses to acquire higher power, more reliable, and more redundant systems.  Also, outsourcing the network in its entirety to a third party presents a unique opportunity to normalize costs.

Sustainability - For most businesses, computers and the associated technologies that support them are one of the greatest consumers of power, along with lighting and HVAC systems.  Improvements in low power devices and power management systems enable business to cut power consumption substantially.  Don’t pay your own power bill?  Watch out – with the escalating cost of power and immanent potential for regulation, some landlords are renewing rental agreements net of power costs.

Even though we are technology consultants, ANALYSYS engages in an annual evaluation of how we employ technology for ourselves, and we look at how we can improve.  In 2009, we engaged in both the Cloud Computing and Sustainability initiatives and experienced tremendous success.  The result was a 50% reduction in internal IT support staff, allowing those personnel to be repurposed to technology consulting initiatives, and a 52% reduction in power consumption.
