Reading Time-approximately: 4 minutesYour data center UPS sizing needs are dependent on a variety of factors. Develop configurations and determine the estimated UPS capacity that will meet your current and future needs. By Robert McFarlane So you need an uninterruptible power supply unit, but you’re having trouble sizing it. How do you figure it out? Some uninterruptible power supply (UPS) systems are rated in kilowatts
Reading Time-approximately: 3 minutesBudget, maintenance cycles and specialized use cases are all reasons to keep legacy hardware. Minimize costs and outages with service contracts and emulation options. By Brien Posey All data center admins face legacy hardware maintenance. In a perfect world, data centers would be equipped solely with the most up-to-date generation of hardware. However, budgetary and operational requirements mean most infrastructure
Reading Time-approximately: 4 minutesAn uninterruptible power supply (UPS) is a device that allows a computer to keep running for at least a short time when the primary power source is lost. UPS devices also provide protection from power surges. By Robert McFarlane A UPS contains a battery that “kicks in” when the device senses a loss of power from the primary source. If an end
Reading Time-approximately: 6 minutesRAID 10, also known as RAID 1+0, is a RAID configuration that combines disk mirroring and disk striping to protect data. It requires a minimum of four disks and stripes data across mirrored pairs. As long as one disk in each mirrored pair is functional, data can be retrieved. If two disks in the same mirrored pair fail, all data will be lost because there is
Reading Time-approximately: 4 minutesWe look at RAID and flash to highlight key choices when it comes to drive data protection. What RAID levels work best with solid state and when is erasure coding a good choice? By Stephen Pritchard RAID systems have been the building blocks of enterprise storage since the 1990s. But RAID – redundant array of inexpensive disks – originated the decade before that in

Reading Time-approximately: 5 minutesThis tip discusses how to choose the right-sized uninterruptible power supply (UPS) for your data center. It also explains common mistakes in UPS sizing and why UPS power ratings can be so confusing. By Bob McFarlane When it comes to buying the right uninterruptible power supply (UPS) for your data center, size matters. This tip explains UPS sizing and capacity
Reading Time-approximately: 3 minutesCritical infrastructure calls for redundancy in the form of N+1 uninterruptible power supply (UPS) systems. Here are some handy N+1 UPS design tips. By Robin Roy N+1 redundancy (or parallel redundancy) is a safeguard to ensure a UPS system’s availability in the event of component failure — especially in a tier 2 or a tier 3 datacenter. When considering an
Reading Time-approximately: 3 minutesInfrastructure power requirements can drive up operating costs. Data center managers can cut their utility bills if they address power needs for CPUs, storage and cooling systems. By Brien Posey Utility bills are no small data center expense. As part of the push to address IT spending, data center managers and organizations continue to look for ways to drive down
Reading Time-approximately: 3 minutesFinding the right server operating temperature can be tricky. ASHRAE standards provide guidance for all server classes and what factors can play into temperature readings. By Jessica Lulka With rack density continuing to increase in data centers, admins must constantly keep an eye on operating temperatures to ensure their servers can run efficiently without any possibility of overheating. Instead of
What is COVID-19?
On 31 December 2019, the World Health Organization (WHO) reported a cluster of pneumonia cases in Wuhan City, China. ‘Severe Acute Respiratory Syndrome Coronavirus 2’ (SARS-CoV-2) was confirmed as the causative agent of what we now know as ‘Coronavirus Disease 2019’ (COVID-19). Since then, the virus has spread to more than 100 countries, including South Africa.
