My life has been a lie. Up until reading this article, I thought my RAID setup was providing a backup of my data. I’ve longed idolized ZFS for its robust snapshotting capabilities, thinking that was a formidable backup as well. My walls of perception have been torn asunder by the fundamental question of what actually is a backup. This Socratic examination goes to the root of the question.
Do you need a script to let you replicate ZFS snapshots for use as backups? Of course you do. Luckily Larry Smith Jr. is on the job. Take a look at what he’s put together. Looks like a good implementation to me. Larry Smith Jr. comments: ZFS – Replication Backups I recently rebuilt my lab NAS […]
The data center is a post-apocalyptic wasteland. Ravaged by an invasive new species called “The Cloud”, previous enterprise technology has been decimated, destroyed or completely mitigated. As fickle CTOs furtively abandon their previously hallowed IT principles, only a select few of the true believers keep the hope alive against an all out victory by The Cloud.
Even these courageous few are forever changed by the experience, for one cannot experience The Cloud an remain inert. No, to survive this powerful force, one must emulate it to survive. From the ashes of the old data center, comes a new, lean, agile force. This is one of their stories. This is Permabit.
You never forget your first love. Whether it’s a high school sweetheart, your first car, your first Linux distribution. The first file system I ever fell in love with was ZFS. Before that, file systems were a total bore, whether it was FAT32 on my Creative Zen MP3 player, NTFS on my Windows box, or […]
The news came out this morning that Dell is in exclusive talks to acquire network storage specialist Compellent for just under $900 million. I will leave it to the real reporters to track the ups and downs of the story; what piques my interest is the value Dell gets from Compellent’s technology and the challenge it poses to the data storage industry.
It’s official… Data deduplication has been added to ZFS (read the link if you’re new to data deduplication). Hats off to Jeff Bonwick and Bill Moore who did a ton of the work in addition to Mark Maybee, Matt Ahrens, Adam Leventhal, George Wilson and the entire ZFS team.Â The implementation is a synchronous block-level […]
Simon Seagrave (http://www.techhead.co.uk/) asked, “How long do you think it’ll be before SSD will overtake SCSI as primary tier 1 SAN storage? Giving a new SSD and SATA tiered mix.”
Short answer: Yes, it will be SSDs + SAS and within 2 years.
The real quesion is when 15K RPM highspeed drives will be replaced with SSDs […]
In this post, Iâ€™ll be discussing some of the analytics features of the 7000 arrays and how the rich data it offers provides customers with added insight into getting the best performance for their money.
Just five days after HP announced it would acquire IBRIX, another scale-out NAS provider has been purchased. LSI announced today that it would acquire ONStor for $25 million in cash. The company sold a range of SAN and NAS storage systems, but was best-known for its Bobcat clustered NAS gateways.
Traditional storage arrays permit the configuration of multiple disk types within a single array. This can range from solid state disks (SSDs), through to fast fibre channel drives and slower high capacity SATA drives. USS operates a slightly different model â€“ all drives in the USS array are high capacity SATA. SSD drives are then used to ameliorate performance on read and write activity in combination with the ZFS file system, by using the SSDs for read caching and write logging.
