To make you more familiar with the concepts of network physical servers and to get acquainted with the reputable vendors of network servers, we have prepared a number of blogs as a series, the different parts of which are as follows:
Part 2: HPE Proliant Servers Family, HPE Rack Servers
Part 3: HPE Tower Servers, HPE SimpliVity, HPE Nimble Storage dHCI
In this series of blogs you will come across a variety of terms, abbreviations, concepts, and technologies. We have tried to explain the general concepts and terms as much as possible in the first part of this series. In the following sections, we assume that you have read first part and therefore we will not re-explain these concepts and terms in the following sections.
Last note, in preparing this blog, we have tried to use the documents and content available on the official website of the manufacturer of HPE servers, namely the website hpe.com. All information is based on the contents of this website.
Part 1: Concepts
iLO: We have already published a blog about this technology. What’s HPE iLO?
HPE Active Health System (AHS): It is an essential component of the iLO Management Engine portfolio.
HPE InfoSight: It for Servers combines the machine learning and predictive analytics of HPE InfoSight with the health and performance monitoring of AHS and iLO to optimize performance and predict and prevent problems.
HDD: It stands for “Hard Disk Drive”.
HDD Form Factor: It is the size or geometry of a data storage device equipped with one or more magnetic-coated spinning platters and one or more moving actuator arms with magnetic heads to read and write information. Two types of HDD form factor are common today: SFF and LFF. SAS and SATA come in both LFF and SFF. SSDs (Solid state drives), which use flash memory chips in place of spinning magnetic platters, almost always come in a 2.5 inch form factor. Read more about HDD form factors.
Small Form Factor (SFF): It is a type of HDD form factor for 2.5 inch hard disk drives.
Large Form Factor (LFF): It is a type of HDD form factor for 3.5 inch hard disk drives.
HP Secure Recovery: During server startup, the system ROM is validated. If the active system ROM fails validation, and the redundant system ROM is valid, the redundant system ROM becomes active. If both the active and the redundant system ROM are invalid, and an iLO advanced premium security edition license is installed, a repair is initiated with components in the recovery set, or the failure is logged and user must complete the repair manually. The server will not boot if the system ROM is not verified.
Trusted Platform Module (TPM): We have already published a blog about this technology. Trusted Platform Module (TPM)
Software-defined networking (SDN): Software-defined networking (SDN) technology is an approach to network management that enables dynamic, programmatically efficient network configuration in order to improve network performance.
HPE Pointnext Services: By clicking on this link, you can get information about this.
HP Advisory Service: HPE Software Licensing Advisory Services for Vendor Workloads helps clients understand software licensing for specific important workloads and develop migration strategies and plans for the future.
HPE GreenLake Flex Capacity: It’s a service from Hewlett Packard Enterprise (HPE) that provides on-premises computing hardware and support together with consumption-based pricing. By clicking on this link, you can get information about this.
HPE Datacenter Care: Read this blog.
SOHO: It is the abbreviation for Small Office/Home Office network. SOHO network is meant for use in small businesses. SOHO is the smallest of the small businesses. The self-employed people and sometimes by a small group people up to 1-5 people are privately own and operate it. These networks are small LANs, and they consists of less than 10 computers. In fact, a SOHO network can be a small wired Ethernet LAN or made of both wired and wireless computers.
Campus LAN: This is a proprietary local area network (LAN) or set of interconnected LANs serving a corporation, government agency, university, or similar organization. In this context, a typical campus encompasses a set of buildings in close proximity. For example, all of the nodes in a campus network are interconnected by means of optical fiber media, taking advantage of Gigabit Ethernet or 10-Gigabit Ethernet technology.
HPE Campus Care: Built for enterprises that are transitioning from traditional networking technologies to new wired and wireless solutions. Campus Care offers tailored advice in areas such as guest policy configuration, software-defined networking (SDN) validation, wireless capacity analysis, and maintenance of optimum network health and performance.
FTTX: Fiber to the x is a generic term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last mile telecommunications. FTTX is a generalization for several configurations of fiber deployment, arranged into two groups:
- FTTP/FTTH/FTTB (Fiber laid all the way to the premises/home/building)
- FTTC/N (fiber laid to the cabinet/node, with copper wires completing the connection)
Gigabit Ethernet (GbE): It is a version of the Ethernet technology broadly used in local area networks (LANs) for transmitting Ethernet frames at 1 Gbps (1000 Mbps).
PoE: Power on Ethernet (PoE) switch is a network switch that utilizes Power over Ethernet technology. These switches can support power and data transmission over one network cable at the same time. This greatly simplifies the cabling process. In fact, POE allows you to power a device like an IP phone or wireless access point over the same cable as your data traffic. The IEEE 802.3 PoE standard sets the maximum power that can be sourced by data terminal equipment (DTE) at 15.4W power.
PoE+: It extends the IEEE 802.3 PoE standard to provide the capability to source up to 30W of power over standard Ethernet cabling infrastructure.
UPoE: or Universal POE. It is a Cisco proprietary technology that extends the IEEE 802.3 PoE standard to provide the capability to source up to 60W of power over standard Ethernet cabling infrastructure.
UPoE+: It is a Cisco proprietary technology that extends the IEEE 802.3 PoE standard to provide the capability to source up to 90W of power.
SFP, SFP+, and QSFP: We suggest you read these two articles. (1) Fiber Optic Cabling Solutions, and (2) SFP vs SFP+ vs QSFP: What’s the difference?
HPE Smart Array S100i: It’s a RAID technology for supporting 6Gb/s SATA. It enables RAID on up to 14 SATA drives connected to the embedded SATA ports on the system board. This software RAID solution is available for HPE ProLiant Gen10 servers and HPE Synergy Gen10 compute modules. S100i Software RAID only supports Windows. Customers using Linux and VMware can use the embedded SATA ports in AHCI mode. In AHCI mode S100i Software RAID is not enabled.
The HPE Smart Array E208i-a: It’s a RAID technology for supporting 12 Gb/s SAS and PCIe 3.0, is an ideal cost-effective solution for RAID 0, 1, 5, and 10 and Software Defined Storage solutions. The HPE Smart Array E208i-a provides enterprise-class reliability, security and efficiency needed to address users evolving data storage needs. This controller operates in Mixed Mode which combines RAID and HBA operations simultaneously. It has eight internal SAS lanes, allowing connection to SAS or SATA drives.
The HPE Smart Array P408i-a: It is an enterprise-class RAID controller that increases performance in messaging, database, or general server applications and delivers 12 Gb/s SAS connectivity on HPE ProLiant Gen10 Servers when connected to 12 Gb/s internal storage devices.
