PowerVault/Unity
Is PowerVault designed to support block and file data natively?
No, It was designed for block only storage.
This software allows multiple virtual machines to run on a single physical server.
Hypervisor
The PowerStore engine that uses virtualized protection instead of traditional RAID
Dynamic Resiliency Engine (DRE)
The voltage ranges of "highline" and "lowline" power
lowline = 100V-125V
highline = 200V-240V
Architecture model of Dell Private Cloud
Disaggregated Architecture
On Unity Arrays, this SSD-based feature allows to speed up reads for frequently accessed data before it is tiered down to HDDs.
Fast Cache Drives
Why do we add in drives to a server even if the customer has a storage array?
To have a backplane on a server in case they want to repurpose the hardware in the future
These two technologies work together in PowerStore to reduce physical capacity
Deduplication and Compression
What are the 3 network interconnects data can be sent over?
Ethernet, Optical, and Fibre Channel
These are used to define desired state and automate cluster deployment and updates.
validated blueprints
Which model of Unity does NOT support in line controller upgrades and why?
Unity XT 380. It has a different chassis size
What does NIC stand for and what does it do?
Network Interface Card and it allows server to communicate over a network to other devices
What is the maximum number of simultaneous drive failures PowerStore can be configured to support?
2
The amount of data that actually gets sent over a network in a certain amount of time?
Throughput
3 main benefits of DPC
- no vendor lock in
- independent scaling
- LCM
Both PowerVault and Unity XT use this kind of controller architecture
Dual/active-active controller architecture?
This is known as the "brain" of the PowerEdge servers
Central Processing Unit (CPU). In charge of executing instructions and processing data for workloads.
What are the 5 TLC Generation 2 PowerStore models?
500T, 1200T, 3200T, 5200T, 9200T
Explain the switch naming convention: S5248F
S = Top of Rack switch (type of switch)
52 = 25GB SFP (generation/model)
48 = 48 ports
F = Fiber Optic/SFP
What is Dell responsible for and what is the customer responsible for
Dell = The platforms (DAP/DPC)
Customer = Licensing/Subscriptions
Distance between sites for synchronous replication must be within ______ miles
60 miles / 100 km
Time =< 5ms round trip
What does iDRAC stand for and why do our customers need it for their servers?
Integrated Dell Remote Access Controller (iDRAC) is a built-in remote management technology in Dell servers, and it is designed for secure local and remote server management.
This metric compares logical used space to physical used space
Data Reduction Ratio (DRR)
Which power cord goes with a voltage of 100V-125V
NEMA 5‑15P to C13
DPC can be purchased for this range of term lengths
1,3,4,5 years
