iSCSI Capable Switches
|
Any GbE switch powerful enough to handle demanding iSCSI traffic without dropping packets and creating latency
Characteristics: Offer dedicated port buffer (shared is not ideal) Support jumbo frames Support flow control Port Buffer is cache (or memory) for each port in a switch. Jumbo Frames are anything over 1500 bytes with 9000 bytes being most common Flow Control allows for storage appliances to send pause frames that prevent a fast sender (host) from overwhelming a slower receiver (storage). **iSCSI Optimized 55xx Series Switch is configured in factory with settings to be plug-n-play with MD32x0i entry level iSCSI SANs Enable Jumabo Frames- Packet from 1500 bytes to 9216 Disable Unicast Storm Control - Security feature Enable Rapid Spanning Tree Enable Flow control |

7 Layer OSI Model
|
Application (Layer 7) supports application and end-user processes.
Presentation (Layer 6) works to transform data into the form that the application layer can accept. Session (Layer 5) establishes, manages and terminates connections between applications. Transport (Layer 4) Usually TCP (the top half of TCP/IP) - provides transfer of data between hosts and is responsible for end-to-end error recovery and flow control. Network (Layer 3) Typically IP (the bottom half of TCP/IP) - Routing and forwarding are functions of this layer, as well as addressing, internetworking, error handling, congestion control and packet sequencing. Data Link (Layer 2) At this layer, data packets are encoded and decoded into bits. The data link layer is divided into two sub-layers: The Media Access Control (MAC) layer and the Logical Link Control (LLC) layer. Physical (Layer 1) conveys the bit stream - electrical impulse, light or radio signal - through the network at the electrical and mechanical level. |

Networking
|
Networking allows one computer to copy files and data to another computer WITHOUT PHYSICALLY VISITING the other computer.
Typically the cables from each computer go to a central point and connect to a device known as a Hub or Switch. A group of computers connected together to share data or services is known as a Network. Networks consist of other devices as well, such as printers, servers, etc. |
|
|
Network Interface Card (NIC)

|
|
Addressing
|
MAC (Media Access Control) is a 48-bit Unique address for any entity on a network
Address format looks like XX:XX:XX:XX:XX:XX where XX=hexadecimal value Address is “fixed” and cannot be changed (sorta) TCP/IP Transmission Control Protocol/Internet Protocol Defines the rules computers must follow to communicate within a network or across the internet. IPv4 Address format looks like 192.168.0.1 4 octets 1 byte per (hence, oct) this is a 32bit value IPv6 up and coming address method for TCP/IP that is 128bit. It looks like--> fe80:0000:8aa:bb43:f3c4:c7db |

NEMA Naming Convention
|
Blank = Non Locking
L = Locking 5 = 120V 6 = 208V P = Plug R = Receptable •L means locking and round. (all 30 and 60 amp circuits typically) •Every source is NEMA convention •Enterprise hardware is IEC, so you are converting to NEMA either from server to wall, OR, via the PDU, or via the UPS (best practice) UL listed continuous run rating is 80% (i.e. 80% of 30 amps = 24 amps) |
|
|
3 types of PDUs
|
•Switched: Provide remote outlet control to eliminate costly service calls by allowing you to reboot locked devices
•Monitored: Provide remote monitoring/ reporting to prevent overloads that cause damage •Metered: Feature built-in load meters that display connected equipment load in amps to prevent overloads and safely optimize load levels |
|
|
Why sell Dell PDU’s?
|
•Integration: Just like Dell UPS these work seamlessly with Dell hardware
•Installation •Tool less installation •Choice of orientation •Management •Easy to read dual color LCD •Power monitoring and Management software •Color coded receptacle groups and circuit breakers •Support •PDUs are completely supported by a Dell three-year warranty (compared to the industry standard of one year) ; Best warranty in the industry |
|
|
Power Equation: Amps * Volts = Watts
|
•Amps = amount of electrical current
•Volts = the amount of force of the electrical current •Watts = how amount of total power is measured. |
|
|
iSCSI Switch Characteristics:
|
•Offer dedicated port buffer (shared is not ideal)
•Support jumbo frames •Support flow control •RSTP (Rapid Spanning Tree protocol) iSCSI traffic ‘bursts’; Disable Unicast Storm Control NFS – Network File Systems – Linux CIFS – Common Internet File Systems - typically associated with Windows |
