What XL models do DCA Cards (Direct Compression) come in?
DCA Cards come in all XL models, x70R4, X90R4, C70R4, C90R4. Not in any other models.
XL is the ____ performance. X is ___ XL in performance. C is the ____ cost and ____ performance option on the exam.
XL is the highest. X is below XL. C is the lowest cost and lowest performance.
Cloud Block Store (CBS) runs what software in either AWS or Azure?
Purity
What is performed post process and will improve the data reduction over time?
Deep deduplication and deep compression.
When a deduplication hash is matched, what does the FlashArray grow it by?
When a deduplication hash is matched, it grows the block by 512
bytes looking for a larger data blocks to deduplicate.
Flash capacity placed in a system =
Raw
Available flash after RAID loss and system
reserve (Can use 40% loss)
Useable
Usable capacity X data reduction
Effective
How Evergreen//One
and //Flex are metered. (host written capacity)
EUC – Effective Used capacity
No distance or
latency limit. Lowest RPO is 10 minutes. Can
replicate to any FlashArray XL, X, C or Cloud Block
Store.
Snapshot Replication AKA Async
No distance or latency limit. Lowest RPO
is a few second
Active DR
11ms replication limit. 0 RPO 0 RTOF
Lowest RPO
Active Cluster
___ is supported in X to X, X to XL, XL to
XL, or XL to X. X or XL to C is not supported.
Active Cluster
___ is supported from any FlashArray to any
FlashArray including X to C and Cloud Block Store
Active DR

are scheduled. Members can be hosts, host groups,
or volumes.
Protection Group
You can place a protection group in a pod to integrate ___ ___ with Active Cluster
Periodic Snapshot
___ Replicates snapshots to non Pure

30 days
___ ___ ___ is vaild for 12 months after delivery and is extended with new capacity purchase.
Right Size Guarantee
___ ___ replaces customer controllers every 3 years, when
they pay for 3 additional years of support.
Ever Modern
___ ___ - Allows a customer to upgrade to higher model of
controllers and get a trade in credit on the current controller.
NOTE: (___ ___) will reset the 3 year Ever Modern Clock to the date
of the )___ ___) Transaction.
Ever Agile
– Provides a trade in credit on old media
when a customer buys new media. Full TB for TB trade in credit given
if the customers buys 4X the capacity (25% off total)
Capacity Consolidation
___ - As a service storage model. Metered on Effective
consumed Capacity (host written non reduced capacity)
Evergreen//One
– Customer owns the hardware and rents the
capacity license to use.
Evergreen//Flex
In performance graphs: r=___, w=___, mw=___, and Q=___
r = read, w = writes, mw = mirrored
writes (active cluster replication performance), and Q =
queue time.
– Shows data path performance from
Storage, to datastore, to Host, to VM guest, to vDisk.
VM Analytics in Pure1
___ is a measure of how busy an array is. For the sake of
this test, think of it as CPU use. Moving to a higher model
will reduce load.
Load
___ and ___ in the GUI dashboard represent usable
capacity.
