Q: What is the underlying media management software in FlashArray that
bypasses traditional RAID?
ANSWER Purity Operating Environment (Purity//FA).
Q: What is the name of Pure Storage's flash-optimized file system?
ANSWER PFS (Pure Flash File System).
Q: What technology allows FlashArray to manage flash directly without a
controller card on the SSD?
ANSWER DirectFlash.
Q: What is the primary benefit of DirectFlash modules (DFMs) over standard
SSDs?
ANSWER Lower latency, higher endurance, and better performance
predictability.
Q: What is the typical latency target for FlashArray//X and //C systems?
ANSWER Sub-millisecond (usually ~0.5ms to 0.7ms).
Q: What is the latency target for FlashArray//E systems?
ANSWER Under 2 milliseconds.
Q: How many controllers does a standard FlashArray chassis have?
ANSWER Two (acting as an active-active pair).
Q: What is the name of the high-availability feature that allows non-disruptive
controller upgrades?
ANSWER Evergreen.
Q: What is NVRAM used for in FlashArray architecture?
, ANSWER To protect metadata and write intents in the event of a power
failure.
Q: How is NVRAM protected from power loss?
ANSWER It is backed by battery-backed capacitors (supercaps) that dump
data to a dedicated flash module if power is lost.
Q: What is the maximum raw capacity of a single FlashArray//X chassis (e.g.,
X90)?
ANSWER Up to 300TB+ of raw flash (varies by exact model).
Q: Which FlashArray model is optimized for capacity and density?
ANSWER FlashArray//C.
Q: Which FlashArray model is optimized for extreme efficiency and entry-level
use cases?
ANSWER FlashArray//E.
Q: What protocol does the out-of-band management port use?
ANSWER IPv4.
Q: What protocols are supported for host data access?
ANSWER Fibre Channel (FC), iSCSI, and NVMe-oF.
Q: Does FlashArray support NFS or SMB natively on //X, //C, or //E hardware?
ANSWER No, file protocols (NFS/SMB) require FlashBlade or a separate file
service appliance.
Q: What is the term for grouping multiple FlashArray chassis together for
scale?
ANSWER A Pod (specifically, a stretched pod or replication pod).
Q: How does Purity handle garbage collection?
ANSWER Inline, in the background, without impacting foreground write
performance.
Q: What is "reduction" in Pure Storage terminology?
ANSWER The combination of data compression and deduplication.
, Q: Does enabling compression or deduplication impact latency on a
FlashArray?
ANSWER No, it is done inline via hardware acceleration without performance
penalty.
Q: What is the default block size for a FlashArray volume?
ANSWER 512 bytes.
Q: Can you change the block size of a volume after creation?
ANSWER No.
Q: What is the maximum volume size supported on Purity//FA?
ANSWER 128 TB (Terabytes).
Q: What happens to data reduction when you enable encryption on a volume?
ANSWER Data reduction still occurs; encryption happens after reduction.
Q: What type of encryption does Purity use at rest?
ANSWER AES-256-XTS.
Q: Where are the encryption keys managed natively on the array?
ANSWER In the array's internal Key Management Service (KMS).
Q: Can Pure Storage integrate with external Key Management Servers (KMIP)?
ANSWER Yes.
Q: What is the name of the feature that ensures data integrity across the flash
media?
ANSWER End-to-end checksumming.
Q: How many disk shelves can be attached to a FlashArray//X?
ANSWER Zero. All flash is contained within the base chassis.
Q: What is a "FlashBlade"?
ANSWER A separate Pure Storage product optimized for unstructured data
(file and object).
Q: What does "Always-on Encryption" refer to?
