Common Data Center Storage and How to Recycle Them Properly

Why Data Center Storage
Data center storage hardware forms the backbone of any data center operation, as it is responsible for storing and managing the vast amount of data that modern businesses generate. However, with the continuous growth of data, there is an increasing demand for more advanced and efficient storage devices in data centers. This article will explore various data center storage devices, common storage devices used in data centers, and how to recycle storage devices to optimize data center operations.

Data Center Storage Devices

Storage devices in data centers can be broadly categorized into three main categories:

  1. Direct-Attached Storage (DAS): This is the most basic type of storage device, where the storage device is directly attached to a server or a computer. DAS is further divided into two categories: internal DAS and external DAS. Internal DAS refers to the storage devices like hard drives or solid-state drives that are installed inside the server. External DAS refers to the storage devices that are outside the server but directly connected to it, like external hard drives or storage enclosures.
  2. Network-Attached Storage (NAS): This type of storage device is connected to the network and can be accessed by multiple servers or computers over the network. NAS devices usually have their own operating system and are often used for sharing files and data among multiple users.
  3. Storage Area Network (SAN): This is a dedicated network that connects numerous storage devices with multiple servers. SAN is often used in large enterprises for high-speed access to large amounts of data.

Common Storage Devices in Data Centers

In data centers, different types of storage devices are commonly used to store and manage data:

  • Hard Disk Drives (HDD): These are the most common storage devices used in data centers. They are cost-effective and provide large storage capacities. However, they have moving parts, which makes them slower and more prone to failure compared to solid-state drives.
  • Solid State Drives (SSD): These are faster and more reliable than HDDs as they have no moving parts. However, they are more expensive and have a limit on how many times you can write data on them.
  • Hybrid Drives (HHD): These are a combination of HDD and SSD. They have a small amount of SSD storage that acts as a cache to speed up access to frequently used data, and a larger amount of HDD storage for less frequently used data.
  • Tape Drives: These are used for backup and archiving data. They are cost-effective and provide large storage capacities but have slower access times compared to HDDs and SSDs.
When Data Storage Devices

OEMs and Common Storage Devices

Original Equipment Manufacturers (OEMs) like Dell, Hewlett Packard Enterprise (HPE), and IBM provide a wide range of storage devices for data centers. Some common storage devices from these OEMs include:

  • Dell EMC PowerStore: This is a mid-range storage appliance that provides high performance and scalability. It supports both SAN and NAS configurations.
  • HPE 3PAR StoreServ: This is a high-end storage array that provides high performance and scalability. It supports both SAN and NAS configurations.
  • IBM FlashSystem: This is a family of all-flash storage arrays that provide high performance and low delays. They support both SAN and NAS configurations.

How to Recycle Storage Devices

Data center storage devices have a finite lifespan and will eventually need to be replaced. However, it is important to properly recycle these devices to ensure that the data stored on them is securely erased and to minimize the environmental impact. Here are some steps to recycle storage devices:

  1. Data Erasure: The first step is to securely erase all the data stored on the device. This can be done using specialized software that overwrites the data with random bits multiple times to ensure that it cannot be recovered.
  2. Physical Destruction: If the storage device is not going to be reused, it is important to physically destroy it to ensure that the data cannot be recovered. This can be done using specialized equipment that crushes or shreds the device.
  3. Recycling: Once the data has been securely erased and the device has been physically destroyed, it can be sent to a recycling facility where the materials can be recovered and reused.
Data Center Device


Data center storage hardware plays a critical role in the operation of any data center. It is important to carefully select the right storage devices for your needs and to properly recycle them at the end of their lifespan. By making smart choices and recycling responsibly, you can optimize your data center operations and minimize your environmental impact.
