The Challenges Enterprise Face Today

Platform virtualization that was once only possible on expensive mainframes has become an indispensable core technology for enterprise IT

Using OpenStack to build a private cloud has become a recent trend in corporate IT architecture

Dilemma of high-cost SSD and high-capacity NL-SAS

The pursuit of uninterrupted operation and high data availability

Enterprises spend massive amounts of money to build out baseline architecture suitable for a VDI deployment

What is ES NAS

Built for Business-critical Applications

The Enterprise ZFS NAS, featuring the brand-new QES (QNAP Enterprise System) operating system. Both the software and hardware architecture were built from the ground up to completely support virtualization environments. It is easy to use, has a low learning curve, and the fastest deployment speed.

4 Reasons Why ZFS Rocks


This technique ensures that data is always consistent on the disk, when data is changed it is not overwritten — it is always written to a new block and checksummed before pointers to the data are changed.

Data Integrity:

The file system uses a 256-bit checksum, which is stored as metadata, can detect phantom writes, misdirected reads and writes, DMA parity errors, driver bugs and accidental overwrites

Data Self-healing:

ZFS’s near bullet-proof data integrity provides self-healing feature that can repair silent data corruption which occurs in mirrored volumes.


RAIDZ gets around “write hole” issue by using a variable width stripe, so every write is effectively a full stripe write. This, together with ZFS's copy on write characteristic, eliminates the RAID 5 write hole completely 

Warranty and SimplyNAS Replacement Services (SRS):

Field-replaceable Unit (FRU) applies not only to the controllers but also to the cooling fans, power supplies, and the BBU battery pack for CF2 (Copy-to-Flash), providing a cost-effective way to maintain complex systems and to replace defective parts.

Coupled with SimplyNAS Replacement Services (SRS) customers can be up and running in no time if any of the replacement parts fail. Call us to today to discuss your requirements and what we can do for you.Call one of our NAS experts TDODAY 407-960-4690
