Today Compellent is pleased to introduce the latest in our unified storage line, the Compellent zNAS , which is our first NAS based on ZFS (Zettabyte file system). Compellent zNAS is ideal for mid-sized and large enterprises with file and block based storage requirements, especially in mixed Unix, Linux and Windows environments.
Why is this important? Because file storage requirements are going through the roof, with analysts like IDC predicting the amount of unstructured data (office docs, videos, graphics files) will increase by more than 60 percent annually through 2012. That's a lot of growth, requiring both granular system intelligence and big file scalability to manage all that data, regardless of size or type, in the most efficient way. The Compellent zNAS was designed with those storage consolidation needs in mind. Here are a few of the product highlights:
-
Unified storage management interface - The zNAS interface integrates file and block storage management tasks. For example, an admin can create file shares that are instantly, thinly provisioned on Compellent enterprise SAN. Other data management tasks such as volume deletion, snapshot creation and system analytics are also available from the unified interface (See sample screenshot)
-
Fluid Data architecture - Regardless of whether the data is written by file-based or block-based applications, the zNAS leverages our Fluid Data architecture to consolidate the data in a virtual pool of storage and provide granular system intelligence to actively manage the data. The solution offers block-based thin provisioning, automated tiered storage, boot from SAN, continuous snapshots and thin replication applications.
-
High-performance NAS hardware - The zNAS ships as a single 1U NAS node or a clustered dual configuration. The NAS comes with dual Intel Nehalem processors and memory up to 48 GB. Because each node is diskless, the management software and NAS image boot from the SAN, which means fewer hardware components to deploy, maintain and upgrade.
-
Single, scalable platform - The back-end storage consists of the Storage Center controller and enclosures that can support any type of drive such as SSD, SAS, FC or SATA. By leveraging a persistent hardware platform and managing just one pool of storage, enterprises can greatly simplify management, improve performance for their applications, and save money on hardware and associated costs.
If it's ZFS, it's got to be massively scalable
- ZFS is an advanced, highly scalable file system: it’s a 128-bit file system addressing 18 quintillion (1.84 × 1019) times more data than current 64-bit systems.
- The practical limitations on file size and directory entries cannot be defined, so basically you’re bound more by the physical capacity of the unified platform - in Compellent’s case that’s 1,008 disks.
- ZFS has advanced error detection and correction, using end-to-end checksums to authenticate data integrity.
- ZFS has other valuable storage efficiency features such deduplication, which is expected to ship later this year on zNAS (end of Q2/beginning of Q3).
We'll ship the Compellent unified storage solutions with zNAS by the end of June 2010, available only through our global network of channel partners.

If you'd like more information on unified storage, join me (@LiemNguyen) and ESG senior analyst Terri McClure (@esganalysttmac) for the next #SANChat on unified storage at 1:30 pm CDT later today, April 27. We will talk about the benefits of scalable NAS, next-generation unified storage technologies and other storage issues.

When it comes to your IT environment, sometimes the best decisions involve an element of risk. Implementing a new technology can be a difficult choice – but the payoff can be pretty big.
Just ask Ben Higginbotham, director of new technology at WhereToLive.com, a company that offers real estate brokers behind-the-scenes applications that support daily property transactions and listings. Ben’s job centers around evaluating new technologies to help manage the data that realtors need – and decide whether the risk of implementation is worth the payoff. Using the Compellent SAN, Ben has created an ideal Fluid Data platform to test new resources and assess new capabilities.
Compellent invites you to join Ben, as well as Compellent storage architect John Dias, for a Twitter Chat we’re calling #SANChat. The very first one will about new technology risks you are taking or considering in the data center – are you curious what others have similarly done? What about the results? Was the payoff worth the risk? Did your recommendations, particularly storage-related ones, generate business-improving benefits in the end? Take an hour to chat with us and share your questions, best practices, and advice about doing something new in storage.
#SANchat Details:
- Wednesday, March 24, 2010, 2:00 pm – 3:00 pm CT
- Topic: Evaluating the Risk of New Technologies
- The hashtag #SANchat will be used to identify the thread for this chat; use the #SANchat identifier to submit questions during the chat session
- If you can’t attend the session, you can submit questions in advance to @Compellent, and we’ll provide these advance topics to our participants for discussion during the chat
- Follow: John Dias: @johnddias, Ben Higginbotham: @bencredible, Compellent: @DellCompellent
- We recommend using the service TweetChat.com to follow the conversation.
