  • Essential Tech Check List: Building & Retrofitting Your Server Room

    Whether you're building a server room, adding on, or moving equipment there are many considerations to mull over. From the basics to alarm systems, it is important to ensure your server room is efficient and to protect your mission critical equipment. Previously in our blog, we have addressed the issues surrounding the microclimate present in your server room; however, it is critical to have an understanding of how a server room should be laid-out and managed. Use our check list as a guide for promoting security, efficiency, and productivity:

    Our Essential Tech Check List

    (1) Your Basics of Space

    • -Examine the layout of the space and how many units of space you have to work with.

    • -The walls (including ceiling) and doors should isolate the sounds that your equipment is creating.

    • -Check to see which way the door opens. There should also be no windows or other entry points other than the doors in the room.

    • -Consider the floor and whether your equipment will need raised flooring. Aim for anti-static floor finishing to prevent an unwanted static charge.

    • -Make sure there is enough clearance for racks and that they are stable enough to hold your equipment.

    • -Check for aisle clearance too, make sure your have enough room for exhaust to escape and not over-heat nearby equipment.

    • -Think about whether you need ladder racks, cabinets, shelves, patch panels, or rack mounts.

    • -Take into weight and size of each piece of equipment into consideration when designing the layout.


    (2) Keeping Your Cool

    • -Check and see what type if centralized cooling is available, whether an under the floor air distribution or an air duct system.

    • -If there is no centralized system available, get an air conditioner or cooling unit that is able to keep your equipment working productively while minimizing energy consumption and costs.

    • -If at all possible, fresh air vents are great and save on energy costs and consumption!

    • -Remove any and all radiators or other heating equipment currently present in the room. You don't need to add heat at all!

    • -Monitor your cooling system(s) to make sure it is working properly, especially when no one is there.

    • -Make sure your cooling units are not too close in proximity to your electrical equipment, think condensation and flooding. Do not place air conditioning units over your servers.

    • -Monitor the humidity to prevent static charge and electrical shorts.

    • -See if a chilled water system is in the budget or find something within the budget constraints to ensure that the hot air has somewhere to go.

     

    (3) Using Your Power

    • -Check to make sure that you have enough outlets to support power to all your equipment and not to overload them.

    • -Get backup power, preferably UPS to prevent data loss from power blinking or outages.

    • -Don't surpass the maximum electrical intensity per unit of space.

    • -Consider shut down capabilities of equipment (SNMP traps for example).

    • -Make sure your equipment is grounded.

    • -Monitor for power outages if you are not using back-up power systems.

    • -Monitor your back up power systems to make sure your mission critical equipment is not failing due to power loss.

     

    (4) Keeping Secure & Safe

    • -Have at least one phone present in the room in case of emergencies.

    • -Either check for a preexisting fire alarm system and install one if there isn't.

    • -Get a fire suppression system if there is not one there. Take into consideration of whether you will have a wet or dry suppression system and the effects that will have on your equipment. (Halon is a great choice!)

    • -Have reliable contacts to help resolve issues immediately, or form a system of escalation.

    • -Monitor for flooding, especially if this has happened historically in the past.

    • -Secure entrances/exits, this is expensive equipment with critical data, you don't want just anyone in there messing around!

     

    (5) Other Considerations

    • -Get the best cabling/wiring available within budget constraints. 

    • -Keep extra cabling/wiring around, because you never know when you may need it.

    • -Consider color coding wires/cables, a little more work now but definitely a time-saver in the future!

    • -Think about lighting: location & heat produced.

    • -If there is someone sharing the space, get them some earplugs! It's going to be loud in there with the equipment being used.

    • -Consider networking/phone lines being run in there and how much space you have left after that.

    • -Plan for future expansion or retrofitting (again).

    • -Leave the service loops in the ceilings.

    • -Label outlets.

    • -Get rid of dust, your equipment hates it!

    • -Check if you have a rodent/pest problem.

    • -Cover emergency shutoff switches so that it can't be accidentally triggered.

    • -Try to centralize the room in the building so that you can eliminate having to use more cabling/wiring than you need to.

    • -Meet OSHA and ASHRAE guidelines as well local codes.

  • It's Hot! It's Cold! Oh No... It's Your Fluctuating Server Room Temperature Again...

    We know that every room, especially a server room, has its own microclimate. Even sensors that are inches apart can read different values! Although similar applications might share the same temperature threshold range, every sensor placement location is unique. It sounds strange; that there would be such fluctuations in temperature within inches, but this happens because your server room has its own minature weather pattern!

    So how do you figure out the correct temperature range for monitoring your server room? Or where to place your sensor? As many conditions as there are for the actual ourdoor weather patterns, there are many variables for sensor placement and operational range because of the changing indoor microclimate.

    Essentially, in order to determine the right thresholds for your server room "environment", you need to acquire adequate baseline knowledge. This process is called "baselining", which involves monitoring your server room first to establish a history of normal conditions. Temperature is a significant threat to your equipment and in order to battle this, you need to discover and establish your server room's microclimate (i.e. baselining)!


    Baselining is basically achieved through studying the space of your server room while considering the components within it. Thic can be done to determine the proper ranges for both temperature and humiditySo what spots are the most critical for consideration when it comes to sensor placement?

    1. Hot Spots
    At the bare minimum, place at least one sensor in a central location in the room. Note: every room has its own mini weather pattern, and conditions from one part to another can vary based on what the room contains and where vents/returns are located. The simplest rule of thumb is that heat rises. So, the higher the sensor placement, the warmer the temperature

    2. Cooling Vent Locations
    Whether it is an air conditioner, economized cooler, or another chilling device, it will affect the sensor reading depending on proximity of the sensor to the vent. If you want to monitor whether your cooling unit may be going out at different times,place a sensor in the air duct and you can determine when the cooling unit is off. Placement of a sensor in close proximity to the cooling unit may cause the sensor to pick up cooling unit "cycles", sending you false alerts in the process.

    3. Exhausts
    Besides cooling vents, you need to also consider hot vents from server cabinets or compressors. Placing a sensor near or in between these areas is crucial as high temperatures can cause damage to hardware. The exhaust-based alerts will draw attention to the high temperatures within the servers, allowing you to prevent loss of hardware (and revenue!)

    4. Ancillary Humidification Systems
    These systems help control humidity. Too much humidity can cause condensation, which leads to electrical shorts. Not enough humidity causes one to have quite the mini-electrifying experience with static electricity at its peak. Place your humidity sensor in a location seperate from the ancillary humidification system in order to prevent the sensor from getting shorted and to avoid false humidity readings.

    By monitoring temperature and humidity, one can have early warning of any disasters looming in your server room. It is always better to prevent a disaster rather than mop up after it (speaking of, flood sensors are great too!).

    Happy Monitoring!

  • Temperature, Humidity or Both, That is the Question

    Historically, temperature monitoring has been one of the most important factors to monitor for sensitive applications.  Whether you’re monitoring server rooms to tell when the AC goes off and jeopardizes costly electronic equipment containing valuable data, or a medical office refrigerator containing perishable vaccines, temperature is one of the most critical parameters to monitor to keep things safe.

    With the advent of low-cost solid state Relative Humidity (RH) sensors, customers with many, diverse applications are reviewing their decision about monitoring humidity as a parameter that may be needed to protect product quality or safety.  For example, servers are generally kept in an air conditioned room, so temperature and humidity are kept at safe levels.  However, a closer look at servers operating in summer months in humid environments has demonstrated that the AC is working very hard to keep temperatures at thermostat set points.    Greenhouses may need to maintain humidity within controlled limits for certain species of plants to thrive.

    While temperatures are maintained within safe operating levels for the most part, RH can creep up significantly as the dehumidification function of the AC system is overwhelmed by 85%-90% humidity.  This is often not a serious problem unless the AC outlet is directly discharging onto electronic racks.  In that case, the rack temperature may be cooled to below the dew point, leading to potential condensation on sensitive electronics.  Over time the condensed moisture will corrode connectors, leading to system performance degradation or, in the extreme, failure.

    Easier to understand may be the case of valuable manuscript storage where extremely high humidity levels may lead to mold or mildew while low levels may lead to paper or parchment cracking.  Here, both would be important to monitor.

    The following table describes various applications where both temperature and RH may be considered and some guidelines as to whether or not adding RH monitoring and alerting may be beneficial.
