Storage Type Assets
Introduction
In the realm of IT asset management, understanding the various types of assets is crucial for effective inventory management, resource allocation, and maintenance. As defined by your program, you have different types of assets, including servers, workstations, switches, routers, storages, HSM (Hardware Security Module), and software. In this article, we will focus on storage type assets, exploring their unique properties and characteristics.
Storage Type Assets: Properties and Characteristics
Capacity
The capacity of a storage device refers to the total amount of data it can store. This is typically measured in gigabytes (GB), terabytes (TB), or petabytes (PB). Storage devices come in various capacities, ranging from a few hundred GB to several petabytes. The capacity of a storage device is a critical factor in determining its suitability for a particular application or use case.
Example: A storage device with a capacity of 10 TB can store approximately 2,000,000 hours of compressed audio or 1,000,000 hours of compressed video.
Drive Bays
Drive bays refer to the physical compartments or slots in a storage device where hard drives or solid-state drives (SSDs) are installed. The number of drive bays in a storage device determines the total number of drives that can be installed. Drive bays can be hot-swappable, allowing administrators to replace drives without powering down the device.
Example: A storage device with 24 drive bays can accommodate up to 24 hard drives or SSDs, providing a total storage capacity of 72 TB (assuming 3 TB drives).
Drive Type
The drive type refers to the type of storage device used in a storage system. Common drive types include:
- Hard Disk Drives (HDDs): Magnetic storage devices that use spinning disks and mechanical heads to read and write data.
- Solid-State Drives (SSDs): Flash-based storage devices that store data in memory chips.
- Hybrid Drives: Combination of HDDs and SSDs, offering a balance between capacity and performance.
Example: A storage device with a mix of HDDs and SSDs can provide a balance between capacity and performance, making it suitable for applications that require high storage capacity and fast data access.
RAID Level
RAID (Redundant Array of Independent Disks) level refers to the configuration of multiple drives in a storage system to provide data redundancy, performance, or a combination of both. Common RAID levels include:
- RAID 0: Striping, which provides high performance but no data redundancy.
- RAID 1: Mirroring, which provides data redundancy but lower performance.
- RAID 5: Striping with parity, which provides a balance between performance and data redundancy.
- RAID 6: Striping with dual parity, which provides high data redundancy and performance.
Example: A storage device configured with RAID 5 can provide a balance between performance and data redundancy, making it suitable for applications that require high storage capacity and fast data access.
Interface
The interface refers to the communication protocol used by a storage device to connect to a host system. Common interfaces include:
- SATA (Serial Advanced Technology Attachment): A widely used interface for connecting storage devices to host systems.
- SAS (Serial Attached SCSI): A high-speed interface for connecting storage devices to host systems.
- FC (Fibre Channel): A high-speed interface for connecting storage devices to host systems over a fibre channel network.
Example: A storage device with a SATA interface can connect to a host system using a standard SATA cable, while a storage device with a SAS interface requires a SAS cable and a SAS host bus adapter.
Network Accessibility
Network accessibility refers to the ability of a storage device to connect to a network and provide access to stored data. This can be achieved through various protocols, including:
- iSCSI (Internet Small Computer System Interface): A protocol for connecting storage devices to a network using TCP/IP.
- FCoE (Fibre Channel over Ethernet): A protocol for connecting storage devices to a network using Ethernet.
- NFS (Network File System): A protocol for connecting storage devices to a network using TCP/IP.
Example: A storage device with iSCSI support can connect to a network using a standard Ethernet cable and provide access to stored data using the iSCSI protocol.
Conclusion
In conclusion, storage type assets have unique properties and characteristics that set them apart from other types of assets. Understanding these properties and characteristics is crucial for effective inventory management, resource allocation, and maintenance. By considering factors such as capacity, drive bays, drive type, RAID level, interface, and network accessibility, administrators can select the right storage device for their specific needs and ensure optimal performance and data protection.

Introduction
In our previous article, we explored the properties and characteristics of storage type assets, including capacity, drive bays, drive type, RAID level, interface, and network accessibility. In this article, we will answer some of the most frequently asked questions about storage type assets.
Q&A
Q: What is the difference between a hard disk drive (HDD) and a solid-state drive (SSD)?
A: A hard disk drive (HDD) uses magnetic storage to store data, while a solid-state drive (SSD) uses flash memory to store data. HDDs are generally less expensive than SSDs but offer lower performance and higher latency. SSDs offer faster performance and lower latency but are generally more expensive than HDDs.
Q: What is RAID and how does it work?
A: RAID (Redundant Array of Independent Disks) is a technology that allows multiple disks to be combined into a single logical unit. RAID provides data redundancy, performance, or a combination of both. There are several RAID levels, including RAID 0, RAID 1, RAID 5, and RAID 6, each offering different levels of data redundancy and performance.
Q: What is the difference between SATA and SAS interfaces?
A: SATA (Serial Advanced Technology Attachment) is a widely used interface for connecting storage devices to host systems. SAS (Serial Attached SCSI) is a high-speed interface for connecting storage devices to host systems. SATA is generally less expensive than SAS but offers lower performance and higher latency. SAS offers faster performance and lower latency but is generally more expensive than SATA.
Q: What is iSCSI and how does it work?
A: iSCSI (Internet Small Computer System Interface) is a protocol for connecting storage devices to a network using TCP/IP. iSCSI allows storage devices to be accessed over a network, providing a flexible and scalable storage solution. iSCSI is commonly used in data centers and cloud environments.
Q: What is the difference between a storage area network (SAN) and a network-attached storage (NAS) device?
A: A storage area network (SAN) is a dedicated network for storing and managing data.
