What remains are racks full of servers, storage systems, and switches that are still operational but no longer needed. Whether it\u2019s a single server room or an entire data center: anyone who wants to sell used servers must have two things in hand at the same time \u2013 the residual value and the data. This guide shows how to do that.<\/p>\n<div class=\"si-tldr\">\n<p><strong>The most important in a nutshell<\/strong><\/p>\n<ul>\n<li>Used servers, storage and network technology often still have a market value \u2013 especially the latest generations with good equipment.<\/li>\n<li>Servers contain more storage devices than you might think: RAID drives, cache SSDs, boot media, memory cards, and tapes.<\/li>\n<li>Storage systems need their own deletion procedures, such as the deletion of individual LUNs.<\/li>\n<li>An inventory list with serial numbers and configurations is the basis for offering, deleting, and documenting.<\/li>\n<\/ul>\n<\/div>\n<h2>Why servers do not belong in the container<\/h2>\n<p>A server that is taken out of service rarely breaks down. It just no longer has a planned use. For many other users \u2013 system houses, laboratories, smaller data centers, development environments \u2013 this exact hardware is interesting. Even individual components such as processors, memory, and power supplies can be reused.<\/p>\n<p>Anyone who discards servers without checking them first is giving away money. Anyone who sells them without checking them first risks a data leak. The right way lies somewhere in between: first delete them securely, then use them for good.<\/p>\n<h2>What makes used servers worth money<\/h2>\n<table class=\"si-table\">\n<thead>\n<tr>\n<th>Factor<\/th>\n<th>Why he counts<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Generation and processor<\/td>\n<td>Newer platforms are much more in demand than older ones.<\/td>\n<\/tr>\n<tr>\n<td>Memory<\/td>\n<td>Large, complete equipment increases the value noticeably.<\/td>\n<\/tr>\n<tr>\n<td>Disks<\/td>\n<td>Deleted, functional drives can be sold together. Destroyed drives are excluded from the price.<\/td>\n<\/tr>\n<tr>\n<td>Power supplies, controllers, network cards<\/td>\n<td>Redundant power supplies and up-to-date maps enhance the attractiveness.<\/td>\n<\/tr>\n<tr>\n<td>Completeness<\/td>\n<td>Mounting rails, track frame and covers are included.<\/td>\n<\/tr>\n<tr>\n<td>Quantity and uniformity<\/td>\n<td>Simultaneously configured series can be better marketed.<\/td>\n<\/tr>\n<tr>\n<td>Condition and origin<\/td>\n<td>Clean operation in an air-conditioned room is a plus.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>In addition to servers, storage systems, switches, routers, and firewalls often have residual value. When it comes to networking technology, you should first clarify whether licenses are tied to the devices and how configurations can be removed.<\/p>\n<h2>The hidden data carriers in the rack<\/h2>\n<p>A laptop has an SSD. A server can have a dozen data drives \u2013 and some of them are not immediately visible to the eye:<\/p>\n<ul>\n<li><strong>Hard drives and SSDs in RAID configuration:<\/strong> Each individual plate contains data fragments.<\/li>\n<li><strong>Cache and boot SSDs:<\/strong> Often installed internally, for example on the motherboard.<\/li>\n<li><strong>SD cards and USB sticks:<\/strong> Often used as a boot medium for hypervisors.<\/li>\n<li><strong>Controller cache:<\/strong> RAID controllers can buffer data.<\/li>\n<li><strong>Magnetic tapes:<\/strong> From backup systems, often in large quantities.<\/li>\n<li><strong>Management Controller:<\/strong> Save access data, network settings, and logs.<\/li>\n<\/ul>\n<p>At Second IT, all delivered devices are specifically tested for storage media \u2013 including hidden hard drives in server cabinets, forgotten USB sticks, or memory cards. More about <a href=\"https:\/\/www.second-it.de\/en\/services\/data-security\/\">Data security<\/a>.<\/p>\n<blockquote class=\"si-callout\">\n<p>Note: When it comes to servers, count not the devices, but the data drives.<\/p>\n<\/blockquote>\n<h2>Deleting in the data center: servers, storage, tapes<\/h2>\n<h3>Server drives<\/h3>\n<p>Working HDDs and SSDs are erased with certified software. Second IT uses Blancco Drive Eraser for this purpose. The software also detects hidden areas (HPA, DCO) and remapped sectors and creates a digitally signed erasure certificate for each data drive.<\/p>\n<h3>Storage systems<\/h3>\n<p>In large storage systems, data is distributed across many drives and organized into logical units (LUNs). For cleaning up such environments, there is the Blancco LUN Eraser. It erases data at the level of the logical units.<\/p>\n<h3>Defective drives and tapes<\/h3>\n<p>Data media that cannot be deleted in a revision-proof manner are destroyed in-house at Second IT in accordance with DIN 66399 \u2013 certified to security level H-5, with destruction certificates and serial number tracking. More information available here. <a href=\"https:\/\/www.second-it.de\/en\/services\/device-destruction\/\">Data carrier destruction<\/a>.<\/p>\n<h2>Process: From the rack to the certificate<\/h2>\n<div class=\"si-steps\">\n<ol>\n<li><strong>Create inventory:<\/strong> Record the manufacturer, model, serial number, and configuration (CPU, RAM, drives) of each device. The more precise the list, the more accurate the offering.<\/li>\n<li><strong>Request an offer:<\/strong> Based on the list, you will receive a quote from Second IT within an average of 48 hours.<\/li>\n<li><strong>Planning shutdown and decommissioning:<\/strong> Clarify the time window, access, contact person on site, and charging station.<\/li>\n<li><strong>Secure pickup:<\/strong> Direct shipment without intermediate storage, GPS-tracked, packed and insured. For smaller quantities, lockable trolleys with a load capacity of up to 750 kg are available.<\/li>\n<li><strong>Collection and Examination:<\/strong> Each device and data carrier is registered using its serial number. You can track its status in the customer portal.<\/li>\n<li><strong>Deletion or destruction:<\/strong> Certified with Blancco or physically according to DIN 66399.<\/li>\n<li><strong>Recycling:<\/strong> Processing and re-marketing, obtaining spare parts or proper recycling.<\/li>\n<li><strong>Conclusion:<\/strong> Certificate of destruction and disposal, audit report and proof of disposal for your documents.<\/li>\n<\/ol>\n<\/div>\n<p>Throughout the entire process, you can see in the customer portal where each device is located and its status. Before devices reach the market, we also remove all markings such as inventory stickers or host name labels that could indicate your company. This way, the origin of the hardware cannot be traced back to you.<\/p>\n<h2>Checklist for data center managers<\/h2>\n<ul>\n<li>Are all systems for monitoring, backup, and license management removed?<\/li>\n<li>Is it clear which data will be migrated and which will be deleted?<\/li>\n<li>Are there devices with special protection requirements, for example from personnel, research or government environments?<\/li>\n<li>Are licenses, maintenance contracts, and warranties cancelled or transferable?<\/li>\n<li>Are the contract for order processing and the handover protocol available?<\/li>\n<li>Who ultimately checks the certificates against the inventory list?<\/li>\n<\/ul>\n<p>Tip from practice: Assign a responsible person for the decommissioning process who keeps all the strings together \u2013 from migration to collection to checking the certificates. This prevents individual devices or data media from disappearing in the limbo between two departments at the end of the process.<\/p>\n<h2>Why Second IT for server procurement<\/h2>\n<ul>\n<li><strong>Everything from one source:<\/strong> Acquisition, logistics, disposal, destruction, refurbishment, resale and disposal.<\/li>\n<li><strong>Own security logistics<\/strong> Instead of changing transport companies.<\/li>\n<li><strong>Blancco ITAD Gold Partner<\/strong> with a certificate of destruction on each data carrier.<\/li>\n<li><strong>Certified management systems:<\/strong> ISO 9001, ISO 14001, ISO 45001 and ISO\/IEC 27001.<\/li>\n<li><strong>Europe-wide service<\/strong> with uniform safety standards.<\/li>\n<\/ul>\n<p>You can find more thoughts on the topic in our articles. <a href=\"https:\/\/www.second-it.de\/en\/blog\/server-room-optimization-hardware-remarketing-advantages\/\">Clean up the server room, fill the cash register<\/a> and <a href=\"https:\/\/www.second-it.de\/en\/blog\/servers-do-not-die-they-wait-for-their-second-spring\/\">Servers don't die<\/a>. For the stock analysis: <a href=\"https:\/\/www.second-it.de\/en\/services\/consulting\/\">Consulting and server procurement<\/a>.<\/p>\n<h2>Don't forget network technology<\/h2>\n<p>When a data center is decommissioned, there are often entire rows of switches, routers, firewalls, and access points. These devices are also valuable \u2013 and they contain sensitive information. Their configurations include IP addresses, network plans, access data, and certificates.<\/p>\n<p>Clarify before handing over:<\/p>\n<ul>\n<li>Are the configurations backed up and then removed from the device?<\/li>\n<li>Are licenses and support contracts tied to the devices or transferable?<\/li>\n<li>Are there any modules, transceivers, or power supplies that should be recorded separately?<\/li>\n<\/ul>\n<p>Second IT also handles network technology, such as from Cisco, in addition to servers, and checks the devices for any remaining data.<\/p>\n<h2>Schedule for a demolition<\/h2>\n<p>A data center decommissioning is a project involving many parties. This sequence has proven to be effective:<\/p>\n<ul>\n<li><strong>Eight weeks earlier:<\/strong> Create inventory, obtain quotes, determine the protection needs of the data.<\/li>\n<li><strong>Six weeks earlier:<\/strong> Complete the migration, set the shutdown dates, and clarify the contract and order processing.<\/li>\n<li><strong>Four weeks earlier:<\/strong> Schedule pick-up times, coordinate access and charging station locations.<\/li>\n<li><strong>Pick-up week:<\/strong> Disassemble the device, match the serial numbers, and hand it over in a disassembled state.<\/li>\n<li><strong>After that:<\/strong> Check certificates, complete inventory, archive documentation.<\/li>\n<\/ul>\n<section class=\"si-faq\">\n<h2>Frequently asked questions about server sales<\/h2>\n<details>\n<summary>Can you sell used servers without risking data?<\/summary>\n<p>Yes, if all data media are deleted or destroyed before resale. It is important that every data media is actually recorded, including boot media and storage cards. You should obtain a certificate with a serial number for each data media. This way you can prove the deletion during audits.<\/p>\n<\/details>\n<details>\n<summary>What information do I need for a quote?<\/summary>\n<p>Manufacturers, model, serial number, and configuration of each device are helpful; that includes processors, memory, and drives. Additionally, there are quantity, condition, and location. The more detailed the list, the more accurate the quote. At Second IT, you can receive a quote on this basis in an average of 48 hours.<\/p>\n<\/details>\n<details>\n<summary>Will the hard drives from the servers be sold or destroyed?<\/summary>\n<p>Both are possible. Functional drives can be certified erased and then reused with the servers, which increases the revenue. If your policies require destruction or the drives are defective, they will be destroyed in accordance with DIN 66399. You determine which path applies to which data.<\/p>\n<\/details>\n<details>\n<summary>What happens to servers that no longer have a market value?<\/summary>\n<p>Older servers also contain usable components and raw materials. Useful parts are recovered as spare parts, and the rest is properly recycled in accordance with the Waste Management Act. The data carriers are previously deleted or destroyed. In this case, you will also receive documentation for your records.<\/p>\n<\/details>\n<details>\n<summary>Can I also sell individual servers or small quantities?<\/summary>\n<p>Yes. Even smaller items can be recycled, such as a single server room in a branch. For smaller quantities, lockable trolleys are a practical solution that can be picked up by a freight forwarder. A list of models and configurations is essential. Based on this, you will receive a quote.<\/p>\n<\/details>\n<\/section>\n<div class=\"si-cta\">\n<p><strong>Dissolving a server room or data center?
