Supported Hardware Upgrades
The following sections provide information about hardware upgrades.
1 GbE FC to 10 GbE FC Controller Upgrade
FS8600 1 GbE FC configurations can be upgraded to 10 GbE FC by replacing the network interface cards (NICs). Contact Dell
Technical Support for details about this upgrade.
24-GB and 48-GB Appliances
The 48-GB FS8600 appliance supports 48-GB controllers only. The 24-GB FS8600 appliance supports 24-GB and 48-GB controllers; however, 48-GB controllers in a 24-GB appliance are limited to 24 GB.
Appliance Replacement
A 24-GB FS8600 appliance can be replaced with a 24-GB or 48-GB appliance.
A 48-GBFS8600 appliance can be replaced with a 48-GB appliance only.
NOTE: All appliances in the system must be equal in terms of client connectivity type (1 GbE or 10 GbE), storage connectivity type (FC or iSCSI), and port count.
System Expansion (Adding Appliance)
A 24-GB FS8600 FluidFS system can be expanded by adding either a 24-GB or 48-GB appliance. If the system includes a 48-GB
FS8600 appliance, the system can be expanded by adding a 48-GB appliance only.
All appliances in the system must have the same client connectivity type (1 GbE or 10 GbE), storage connectivity type (FC or iSCSI), and port count.

*Snapshot creation and expiration rate
FluidFS supports from 20 to 300 snapshots per hour system-wide (across all NAS Volumes). The supported number of snapshots per hour varies based on the following factors:
● Load on the system . When a snapshot is expired on FluidFS, the background reclaimer process crawls the file system to reclaim space to the NAS pool. If UNMAP is enabled, the process also UNMAPs space on the SAN backend. The reclaimer process is resource-intensive, and if there is a large amount of load on the system, fewer snapshots per hour should be used to prevent the snapshot reclaimer from affecting end users.
○ Load on the system from external SMB and NFS clients. If the system is under heavy load to service SMB or NFS clients, it will have less system resources available for snapshot expiry. For systems under heavy load, fewer snapshots per hour should be used.
○ Load on the system from FluidFS Replication or NDMP backups. For systems under heavy load due to replication or
NDMP backups, fewer snapshots per hour should be used.
○ The capabilities of the backend SAN. FluidFS clusters that are using a backend SAN with SSDs can support more snapshots per hour than backend SANs using slower spinning disks.
● Content of the snapshots . When snapshots are expired, the snapshot reclaimer crawls the file system to locate freed blocks. Depending on the content of the snapshots, the reclaimer could take more or less resources to expire them. The resources that the snapshot reclaimer uses to expire snapshots is based on:
○ Amount of data that is unique to the snapshot that is being expired. Snapshots that contain a larger total amount of data take more resources to expire.
10 FluidFS File-System Metrics
○ The makeup of the data. Snapshots which contain many small files result in a more randomized access pattern and take longer to expire and consume more system resources. Snapshots with large files being reclaimed result in a more sequential access pattern and consume less system resources.
○ Potential inode imbalance between file system domains. If there are FluidFS File System Domains which contain a disproportionately larger number of inodes than other File System Domains, the snapshot takes longer to expire, as the reclaimer process could be bottlenecked on one File System Domain.

NOTE:
● Quotas for Active Directory (AD) and NIS/LDAP users are independent of each other, even if users are mapped automatically or manually. For NAS volumes with mixed security styles, separate quotas should be set for AD and NIS/
LDAP users.
● For NAS volumes with NTFS or UNIX style permissions, one unique quota should be set for each user. For mapped users, the usage and limits are applied using the target identity and are shared with the native Windows or UNIX account.
● In general, Dell recommends using the NTFS security style in mixed environments.

FluidFS Replication
Note the following information regarding FluidFS replication:
● Replication can be performed from FluidFS v5.x to FluidFS v6.x. Replication between systems running different major versions should be performed only during a short-term update, and is not recommended as a normal operating state.
● Replication partners can differ in network interface speeds (1 GB or 10 GB) or in memory size (24 GB or 48 GB).
The following table lists replication-compatible systems, assuming they satisfy all other conditions:
