Storage limits

Cluster-Mode System Manager Help : Cluster-Mode : Storage node : Storage limits

There are limits for aggregates, FlexVol volumes, traditional volumes, FlexCache volumes, FlexClone volumes, files, and LUNs, qtrees and RAID groups that you should consider when planning your storage architecture.

Limits are listed in the following sections:

•	Volume limits

•	Aggregate limits

•	RAID group limits

•	RAID group sizes

•	Minimum sizes for root FlexVol volumes

Limit	Native storage	Back-end storage arrays	Notes
Mirrored aggregates Maximum suggested per system	64	64	You can create more than 64 mirrored aggregates on a storage system, but doing so could cause plex synchronization problems after certain types of failures.
Array LUNs Minimum size for root volume	N/A	Model-dependent	See the V-Series Support Matrix.
Files Maximum size in 32-bit FlexVol volume	16 TB	16 TB
Files Maximum size in 64-bit volume	16 TB	16 TB
FlexCache volumes Maximum per node	100	100
FlexVol volumes Maximum per node	All other models: 500	All other models: 500	In an HA pair, these limits apply to each node individually, so the overall limit for the pair is doubled.
FlexVol volumes Minimum size	20 MB	20 MB
FlexVol volumes (32-bit) Maximum size	16 TB	16 TB
FlexVol volumes (64-bit) Maximum size	Model-dependent	Model-dependent	See the System Configuration Guide.
FlexVol root volumes Minimum size	Model-dependent	Model-dependent	See table below.
Links (hard) Maximum per parent directory	99,998	99,998
Qtrees Maximum number per volume	4,995	4,995	Qtrees cannot be created in a striped volume.
Subdirectories Maximum per parent directory	99,998	99,998
Snapshot copies Maximum per FlexVol volumeor striped volume	128	128
Striped volumes Maximum size	1 PB	1 PB	16 TB per member aggregate

Aggregate limits

Limit	Native storage	Back-end storage arrays	Notes
Aggregates Maximum per system	100	100	In an HA pair, this limit applies to each node individually, so the overall limit for the pair is doubled.
Aggregates (32-bit) Maximum size	16 TB	16 TB	For striped aggregates, each member aggregate can be up to 16 TB.
Aggregates (64-bit) Maximum size	Model-dependent	Model-dependent	See the System Configuration Guide.
Aggregates Minimum size	N/A	10 GB
Array LUNs Maximum per aggregate	N/A	Model-dependent	See the V-Series Support Matrix.
RAID groups Maximum per aggregate	150	150

RAID group limits

Limit	Native storage	Back-end storage arrays	Notes
RAID groups Maximum per system	400	400
RAID groups Maximum per aggregate	150	150

RAID group sizes

RAID type	Default size	Maximum size	Minimum size
RAID-DP	ATA/BSAS/SATA: 14 FC/SAS: 16 SSD: 23	ATA/BSAS/SATA: 20 FC/SAS: 28 SSD: 28	3
RAID4	ATA/BSAS/SATA: 7 FC/SAS/SSD: 8	ATA/BSAS/SATA: 7 FC/SAS/SSD: 14	2
RAID0	8	26	1

Minimum sizes for root FlexVol volumes
