Increased financial pressures and economic uncertainty have begun influencing IT infrastructure and hardware decisions. IT teams are facing the reality of tighter budgets and the push to deploy cost-reduction strategies<\/a>. It\u2019s common for companies to extend hardware refresh cycles<\/a> to delay significant CapEx investments. The practice of prolonging equipment life cycles isn\u2019t limited to small- and medium-sized businesses; enterprise and big tech companies, including Amazon Web Services (AWS),<\/a> are also following suit. OEMs cite the reliability bathtub curve and encourage customers to follow a 3-to-5-year hardware refresh cycle. The truth is there\u2019s an opportunity to maximise hardware investments by lengthening equipment’s useful life. <\/p>\n\n\n\n

Sometimes a hardware refresh is the best solution to meet demands, and that\u2019s okay! However, if your current IT infrastructure is meeting performance, capacity and power requirements, extending the life of your investment is a great option. Not only can delaying a hardware refresh reduce CapEx and OpEx spend, but it also reduces unnecessary waste, greenhouse gas emissions (GHG) and time spent managing the initiative.  <\/p>\n\n\n\n

With new generations of hardware, you\u2019ll notice incremental upticks in the packet size, throughput and megabits per second (mbps). Why invest critical IT budget dollars in new equipment if performance increases are minimal?<\/strong> <\/p>\n\n\n\n

Hardware reliability and the bathtub curve<\/strong><\/h2>\n\n\n\n

The bathtub curve reliability theory suggests equipment failure rates are higher when the hardware is new to the market, decreases in the middle of the product\u2019s life cycle and increase again toward the End of Service Life (EOSL).<\/a> Although the bathtub failure curve is typically accurate for products beyond IT infrastructure, it doesn\u2019t apply to all data centre equipment. <\/p>\n\n\n\n

\"An<\/figure>\n\n\n\n

At Service Express, we\u2019ve collected over 20 years of service ticket data from over half a million devices to understand equipment longevity and reliability. The data shows that critical and non-critical server and storage failures don\u2019t follow the bathtub curve reliability theory as expected. Instead, most equipment remains highly reliable for over 10 years. <\/p>\n\n\n\n

Evaluating your hardware refresh cycle<\/strong><\/h2>\n\n\n\n

Now that we know data centre equipment is reliable beyond the typical 3-to-5-year refresh cycle, what\u2019s the best action plan for your organisation? Below are several options to help inform your next hardware refresh initiative.  <\/p>\n\n\n\n

\n

Purchase new equipment<\/strong><\/h3>\n\n\n\n
\n
\n

Advantages<\/p>\n\n\n\n

\n

Newer equipment<\/p>\n\n\n\n

\n\n\n\n

It may increase productivity, capacity, compatibility and speed (depending on the product)<\/p>\n\n\n\n

\n\n\n\n

Bundling equipment maintenance with the purchase may decrease OpEx costs during the support agreement. <\/p>\n\n\n\n

\n\n\n\n

New equipment may use less electricity over time. <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n

Disadvantages<\/p>\n\n\n\n

\n

Large upfront CapEx investment <\/p>\n\n\n\n

\n\n\n\n

May have frequent firmware updates and bug fixes in the first several years. <\/p>\n\n\n\n

\n\n\n\n

Considerable time investment to ensure systems are up and running. <\/p>\n\n\n\n

\n\n\n\n

Potential for downtime or interruptions in service <\/p>\n\n\n\n

\n\n\n\n

Hardware support costs increase as equipment ages.  <\/p>\n\n\n\n

\n\n\n\n

Manufacturing new equipment produces around 60 tons of CO2.<\/a> <\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

\n

Leverage recertified, refurbished or previous generation hardware<\/strong><\/strong><\/h3>\n\n\n\n
\n
\n

Advantages<\/p>\n\n\n\n

\n

Offers 30\u201360% savings compared to purchasing new OEM equipment.<\/p>\n\n\n\n

\n\n\n\n

Ability to purchase hardware you need to build the right solution and meet requirements. <\/p>\n\n\n\n

\n\n\n\n

Similar performance to newer generation equipment <\/p>\n\n\n\n

\n\n\n\n

Options for data centre support with third-party maintenance (TPM)<\/a>  <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n

Disadvantages<\/p>\n\n\n\n

\n

Recertified and refurbished hardware is typically not eligible for OEM support. <\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

\n

Delay your hardware refresh<\/strong><\/strong><\/strong><\/h3>\n\n\n\n
\n
\n

Advantages<\/p>\n\n\n\n

\n

Preserves CapEx budget. <\/p>\n\n\n\n

\n\n\n\n

Apply your savings to other areas of the business or more critical IT initiatives. <\/p>\n\n\n\n

\n\n\n\n

Set your pace for hardware refresh cycles to align with CapEx and OpEx forecasts. <\/p>\n\n\n\n

\n\n\n\n

Will be reliable for over 7\u201310 years. <\/p>\n\n\n\n

\n\n\n\n

Experience 50\u201370% savings off OEM post-warranty support costs with TPM. <\/p>\n\n\n\n

\n\n\n\n

Extending equipment life saves around 50 tons of CO2<\/a> compared to purchasing new OEM equipment. <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n

Disadvantages<\/p>\n\n\n\n

\n

You won\u2019t have the latest and greatest equipment on the market. <\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

Instead of sticking with the status quo and following the 3-to-5-year refresh cycle, there\u2019s an opportunity to weigh your options.  <\/p>\n\n\n\n

Extend the life of your IT equipment<\/strong><\/h2>\n\n\n\n

As always, there are a handful of reasons why an organisation needs to upgrade or refresh its hardware. If your equipment meets immediate needs, postponing a hardware refresh is an excellent option to save time, money and resources.  <\/p>\n\n\n\n

The good news is that TPM can help assist with evaluating your IT infrastructure strategy and providing equipment longevity and reliability insights for educated decisions. By combining longevity studies with real-time reliability data, IT teams can plan more efficiently, budget more strategically and allocate resources to other business priorities. <\/p>\n","protected":false},"excerpt":{"rendered":"
