to
2004-12-14
2. Training content: Dell / EMC fiber channel storage device
3. schedule:
2004-12-13
SAN basic knowledge and EMC configuration process
2004-12-14
Actual configuration Dell / EMC CX300
4. Technical benefits:
1) Direct Additional Storage (DAS), Network Additional Storage (NAS) and Storage Area Network (SAN)
For further information, please refer to SAN, NAS and SCSI comparison test
2) What is EMC?
The Dell / EMC network storage system is a shared, universal, highly available infrastructure, overwriting a wide range of storage solutions from the working group to the data center, including the SAN, NAS, and DAS environments. The disk drive of the Dell / EMC array can extend from 5 to 240, without moving data from the original hard drive. In addition, modular design based on standardization technologies also enables customers to start from smaller configurations such as CX300 arrays, and gradually expand from the demand and business growth to the CX500 or CX700 array. In terms of database software, Dell's Navisphere, SnapView, and MirrorView and other software product lines can focus on unified management and comprehensive data protection, and greatly reduce costs.
3) What is the advantage of EMC and existing traditional technology?
l High availability - modular, redundant hardware architecture, hot-swappable parts
l Data Integrity - Cache Jump, Data Protection, Patent SNIIFFER Data Protection Firmware
l Sclectability - Implementation of the disk drive or expanded chassis by heat delivery; upgrade to CX500 or CX700 without moving data
l Manageable - Simple and powerful Navisphere management software reduces management costs
l Excellent performance - CX300 buffer IOP performance is 50,000 times, and can provide continuous bandwidth of up to 680MB / sec
l Additional data integrity includes cache vaulting, data scrubbing, and end-to-end checking (end-to-end checking)
l Rack density - accommodate two storage processors, spare power supplies, and up to 60 Fiber Channel Disk Drivers in 13U rack space

5. Personal thinking and summary:
1) Is there a revolutionary breakthrough in technology?
After I came back, I would like to see how much technical breakthroughs have been involved in this training content? Suddenly thinking that if it is technical, there is a leap and breakthrough, why do DELL wants to fight in the data storage market?
2) Reflections on redundancy and paradigm
Why is there a paradigm in the database design, why there is a large amount of ubiquitous redundancy in the data storage system (including redundancy of multiple physical paths formed by multiple devices), these both have conflicts, and what is the relationship?
3) Does the company need to unify clothes when they do training?
4) How to improve the company employees in the external situation?
5) In the face of new technologies, new methods, how should companies guide employees' technical orientation?
6) Thinking on the company's document
l Each document must have its existing value
l Can not play a key role in the project as much as possible don't spend great effort
l Understand the role of each questionnaire: what needs to investigate (can play a key guidance in the project progress process)
l Pay attention to technical documentation within the project group
7) A number in training
Strengthening English Applications is the necessary conditions for company development and personal growth
It is best to have a comprehensive training before the application of new technologies, so you can look at a technical photo from a certain level:
