Array Features
Arrays provide features to enhance performance, value, and ease of use. The all-inclusive features described in this documentation do not require extra licensing.
Feature | Function | Benefit |
---|---|---|
Core Functionality | ||
Dynamic Caching | Reads active data from flash cache, which is populated on writes or first read | Accelerates read operations, with sub-millisecond latency |
Write-Optimized Data Layout | Coalesces random writes and sequentially writes them to disk as a full stripe | Accelerates writes as much as 100x, and gets sub-millisecond latency and optimal disk utilization |
Universal Compression | Always-on inline compression for all workloads | Reduces capacity needs by 30-75%, depending on the workload, with no performance impact |
Thin Provisioning | Allocates disk space to a volume only as data is written; thin provision "stun" is supported to add greater flexibility | Pools storage, shares free space, and maximizes utilization |
Offloaded Data Transfer (ODX) for Windows | Interacts with storage devices to move data through high-speed storage networks | Improves file copy speed |
Scale Performance | Non-disruptively upgrade controllers or swap in higher capacity SSDs | Scales performance to manage large amounts of active data |
Scale Capacity | Non-disruptively add external disk shelves | Increases storage capacity to 100s of TB per system |
Instant Snapshot and Recovery | Backs up and restores data using point-in-time, space-efficient snapshots taken at regular intervals | Retains months of frequent snapshots, which improves RPO with no performance impact. Eliminates backup windows and speeds up restores, which improves RTO. |
WAN-efficient Replication | Replicates the compressed data changes to the secondary site for disaster recovery | Deploys affordable and verifiable disaster recovery and efficiently backs up remote sites over the WAN |
VLAN Tagging | Part of the 802.1Q frame header containing a VLAN ID between 1 and 4094 that identifies the VLAN to which the frame belongs | Allows a switch to forward that frame only to the appropriate VLAN |
Zero-Copy Clones | Creates copies of existing active volumes without needing to copy data | Creates clones in seconds and saves disk space, which is ideal for VDI and test/development environments |
Host and Application Integration | ||
Custom Application Profiles | Predefined policies for block size, caching, compression, and data protection for Microsoft applications and VMware virtual machines | Eliminates the need to manually tune storage and data protection configurations |
Windows VSS Enablement | HPE Storage Driver for the Microsoft VSS framework for consistent backup | Takes application-consistent backups and simplifies data protection for Exchange and SQL Server |
VMware Integration | Monitors, provisions, and takes snapshots from VMware vCenter | Manages storage from vCenter and takes consistent backups of virtual machines |
VMware Site Recovery Manager Adapter | Supports disaster recovery automation for VMware including failover/failback | Simplifies disaster recovery, including testing failover/failback |
Management and Support | ||
Proactive Wellness and DNA | Real-time monitoring and analysis; sends alerts on critical issues | Spots and remedies potential issues to maximize uptime, performance, and utilization (no user data is accessed or collected by DNA) |
Secure Remote Support | Allows remote troubleshooting, configuration, and problem resolution | Reduces burden on IT staff and quickly resolves problems |
Non-Disruptive Upgrades | Upgrades software with no disruption to applications | Maximizes uptime and user productivity through continuous availability |
NOTE: Recovery Point Objective (RPO) and
Recovery Time Objective (RTO) are among the most important parameters of a disaster
recovery plan.
- RPO: The point-in-time to which systems and data must be recovered after an outage. The interval reflects the amount of data loss a business can survive.
- RTO: The amount of time it takes to recover systems and data after an outage. The interval reflects the amount of downtime a business can survive.
For RPO and RTO, a shorter time interval is better.
