Datacenter Fundamentals
Components of a CPU
CPU
RAM/Cache
HDD/SSD
NIC
DAS? Pros and Cons?
Direct Attached Storage
pro: inexpensive and simple to deploy/configure
con: App/Data siloed creating single point of failure. Limited scalability
4 Main Backup Challenges
Time
Capacity
Risk
Management
What is HCI?
Compute, Storage, Networking all in one
3 Models of Cloud? Explain each briefly
IAAS
PAAS
SAAS
How does Dell EMC modernize an IT Center
Modernize
Automate
Transform
Bonus Points: the 6 Pillars of a modern data center?
Dual Active Controllers vs Active Passive
Active Passive- creates bottlenecks and latency
We build our arrays from the ground up to support flash so controllers don't bottleneck with speed of flash
Inline vs Post Process
Include pros
Inline dedupes in processor before it's written to the disk
- buy less storage upfront & scale less often = lower tco and capex
Post Process is after data is written to disk upfront for a full backup
How does VxRail Scale?
Node based architecture - add compute and storage at the same time
3 nodes-64 nodes
Cloud Deployment Options
Pros/Cons
Public-
Pro: cheap, less infrastructure management, scalability
Con: Control, costly at scale, SLAs, Security
Private-
Pro: IT on demand, MC App Availability, Scalable, Chargebacks, Visibility
Con: Cost upfront, complexity with management, problems with legacy infrastructure
Multicloud-
Pro: Flexibility to innovate at speed, optimize dif providers, not limited to specific set of services
Cons: Security, Complexity
Kinds of Data and the protocols they speak?
- Unstructured, file, speaks CIFS and NFS
- Structured, block, speaks FC and icscsi
FAST
Fully Automated Storage Tiering
Fast Cache- short term
Fast VP- long term along Flash- SAS- NL SAS
Customer had a failed restore..?
DIA
HCI Eliminates?
Tech refreshes and data migrations
Large infrastructure and app silos
Costly fibre channel
Management problems
Storage and cpu added separately
What is VCF and what are the components of VCF?
VmWare Cloud Foundation
- NFX
- VSphere
-VSan
- VCenter
-VRealize
Workload requirements
Capacity, Availability, and Performance
Flash Story
2008
pbff- tlc/active active
Performance: 10,000 vs 200 IOPS
Efficiency: More TB, 1/10 the power 1/4 the cooling, 3-5 years vs 7-10 years
Reliability: No moving parts, AF provisions workloads
Customer is missing backup windows..?
DD BOOST
What doesn't belong in VxRail?
Extremely large databases
Large file deployments
HPC with massive calculations
True archiving/ Long term storage
