DES-1221 Courses’ Overview

When it comes to the training touching on Concepts, Features, as well as Migration for PowerStore, it covers discussions around the basics of this product as well as migration from external storage to PowerStore. The audience of interest includes professionals who position, design, deploy, manage, and support solutions with the use of PowerStore systems. Anyone looking for knowledge on the core topics concerning PowerStore are free to undertake the training. Note that potential learners are expected to be familiar with the following:

• Basic administration for MS Windows user, domain, and file
• Software technologies used in customer-associated environments that include end-user apps, OS, databases, and more
• Ethernet as well as TCP/IP networking

Those who complete the course will be skilled in applying key use scenarios; discussing configuration as well as modes for PowerStore products; describing base enclosure for PowerStore; and identifying switching options for networking. Clarity is also expected in spheres such as scaling options for hardware; PowerStore licensing; locating reference guides as well as information for PowerStore; verifying requirements for host MPIO; administering operations for data migration; and others. The outline of the course also includes an introduction to PowerStore, hardware and software, and reference documentation for PowerStore. The two plans are packaged with practical exercises taking place in a lab-based environment.

The course covering PowerStore Implementation & Administration differs in duration based on the mode of delivery. Both the classroom and virtual classroom programs go for 5 days each, while the on-demand one runs for 21 hours in total. The purpose is to instruct students on matters of PowerStore systems physical installation as well as cabling. Captured is initializing and deploying instructions and practice opportunities for achieving function production states for storage. Daily tasks on administrating block, file, as well as VMware services and resources for storage will be provided as well. Course content also includes PowerStore system software and hardware upgrades, as well as basic troubleshooting.

NEW QUESTION 30
Correctly arrange the sequence of the write operation in PowerStore.

Explanation

Write Operation
The graphic explains the process when the PowerStore receives a write request.

1: Step 1.
In this example, an I/O enters Node B and is saved within the Node
DRAM memory. The I/O is analyzed to determine:
1. What type of I/O it is.
2. What resource it is intended for.
3. The location within the resource being updated or requested.
4. And other metadata information.
2: Step 2.
If the I/O is determined to be a write, the data is copied into the write cache on the NVRAM drives. After the information is stored within the write cache, the information stored within the DRAM memory is considered clean as it no longer has the latest copy of the information. This data then becomes part of the read cache, until it is later replaced in cache by newer or more highly accessed data.
3: Step 3.
For each write I/O that enters the system, the information is passed
between the Nodes using tokens. This operation updates the peer node that a new write has been received and that it has the newest copy of the data. A token includes information about the I/O such as what resource was updated and the address within the resource that was updated. A token also includes information Data Efficiency about the location the I/O was saved to within the write cache. If the peer Node requests that information, the Node can access the data within the NVRAM drives using its own internal channels.
4: Step 4.
After the information is safely stored on the nonvolatile media of the NVRAM drives and all other actions are complete, the host is acknowledged.
5: Step 5.
After the host is acknowledged, data is copied from the Write Cache and is passed through the deduplication and compression logic. The remaining data is then assembled into 2 MB stripes and saved to the back-end storage.
