PowerVault/Unity
Is PowerVault designed to support block and file data(Unified storage)?
No, It was designed for block only storage.
This software allows multiple virtual machines to run on a single physical server.
Hypervisor
DRE uses extent-based RAID to write data across all disks in the storage pool. What is this method also called?
Striping
Which EMC product is the predecessor to the PowerStore?
Compellent
PowerFlex uses this type of architecture to scale compute and storage independently while still incorporating LCM
Disaggregated Architecture
Why should you sell a ME5224 over a ME5212 to a customer?
The base enclosures are roughly the same price but now the customer gets 2x the drive slots for future expansion.
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
True or False: all PowerStore drives are FIPS-rated, self-encrypting drives
False - all drives are self-encrypting, but FIPS drives are not standard
What is the difference between a SAN and a NAS?
A SAN provides block-level access to data over a dedicated high-speed infrastructure, often using Fibre Channel or iSCSI.
A NAS connects directly to a standard Ethernet network and provides file-level access using protocols like NFS or SMB.
PowerMax supports this data service to ensure data is encrypted at rest.
Data at Rest Encryption (D@RE)?
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
What are the 3 media formats data can be sent over?
Ethernet, Optical, and Fibre Channel
True/False: PowerFlex requires management nodes
True!
The Metadata Management (MDM) cluster supervises storage cluster health and configuration.
Typically deployed as a cluster of 3 or 5 nodes for high availability.
The benefits of ADAPT software are..
Faster rebuilds, better data protection, better performance, and a simplified user experience.
Explain the naming convention of a PowerEdge R7725
Rack server, 7 series (2U), 17th gen, 2 Sockets, AMD
What are the 5 TLC Generation 2 PowerStore models?
500T, 1200T, 3200T, 5200T, 9200T
The Unity storage arrays succeed which EMC storage product?
VNXe
PowerMax uses this type of media to deliver ultra-low latency and high throughput.
NVMe (Non-Volatile Memory Express)
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.
What is the software that allows Powerstore to be used as storage in Dynamic Nodes?
What is the difference between Memory and Storage?
Memory = RAM. Used in servers to keep data near the processors. Power can be cut and memory will be erased
Storage = long-term retention of data. Power can be cut and the data will remain
In an independent deployment of PowerFlex, where does the SDC and the SDS live?
In an independent deployment of PowerFlex, the SDC (Storage Data Client) lives on a PowerFlex Compute Nodes and SDS (Storage Data Server) live on PowerFlex storage nodes
