사고 픈거 - drobo 드로보 개인 파일 스토리지

지금 까지 컴퓨터를 사용하면서 하드디스크가 깨지는 경험을 딱 한 번 해봤습니다. 삼성하드디스크였는데 좀 사용하다보니 먹통이 되더군요.

그 원인은 조립 컴퓨터를 샀었는데..  조립 당시 하드디스크 나사가 배송이 되면서 풀렸었습니다. 그 충격으로 인해서 좀 사용하다보니 뻑이 나더군요...   A/S센터에 가니 그냥 새 하드디스크로 교체를 해주었지만.. 그 안에 있는 데이터는 그냥 날려버린 것이죠..

그 이후에는 그런 사례들을 전산센터에서 종종보고 했는데 직접 경험하지 않다보니 데이터 보존의 중요성을 망각하게 되는 것 같습니다.

지금 상황에서는 데이터의 보존보다도 용량의 한계를 느껴서 나스가 필요한 실정이 되어 버렸네요.

기존에는 꾸준히 시놀러지사의 나스를 보아왔었는데..  최근에는 드로보 제품으로 눈이 돌아가네요...

아직, 가격이 쎈지라...    그래도 데이터의 안정적인 보관을 위해서는 꼭 필요한 아이템 중에 하나가 아닐까 합니다.

In fact, even if you're now using USB 2.0, the new Drobo is up to three times as fast its predecessor in typical usage. Consumer Mindset, Enterprise Feature Set. Drobo was designed to meet a stringent design requirement: Anyone should be able to use Drobo regardless of technical experience. It is ready to go out of the box and will always stay that way. Drobo does all the work of managing an enterprise-grade your storage system for you. No Software or Drivers are Needed! The Drobo magic comes from the software that's built into the hardware called BeyondRAID—an advanced storage technology. Drobo does everything for you from expanding capacity when you add a drive, to self-healing around drive failures and data errors. Drobo also includes a powerful desktop software utility called Drobo Dashboard that shows you what Drobo is up to and adds important functionality including firmware updates, formatting options and email alerts. Additional Features Drobo Technology     BeyondRAID Technology   File System and Operation System Agnostic   Mixed Drive Capacity Utilization   Redundantly Safe   Proportional Rebuild Times   Self-Managing   Thin Provisioning   Self-Healing   Smart Volumes   Storage Virtualization   Drive Reordering BeyondRAID™ Technology Every Drobo product comes with the revolutionary BeyondRAID storage technology — the next generation of redundant disk protection. BeyondRAID will not only keep your data safe, but will also increase uptime and availability. BeyondRAID technology offers several improvements over traditional RAID-based storage systems, including the flexibility to replace failed disks and increase capacity all without costly downtime. Key features of BeyondRAID include:   Data protection against hard disk failure   Instant capacity expansion without downtime   Self-management   Automatic healing File System and Operating System Agnostic Drobo and its underlying BeyondRAID technology currently support the Windows, Mac and Linux¹ platforms, with file system support for NTFS, HFS+, EXT3 and FAT32. Since Drobo is a block level system, it easily adapts to almost any environment. Mixed Drive Capacity Utilization Grow storage in line with data capacity needs with minimal effort. To add capacity, customers can simply insert a new hard disk or replace the smallest disk with a larger one, even when all four disk bays are full. Unlike traditional RAID systems, the BeyondRAID technology enables IT managers to efficiently mix n’ match disk brands, capacities and speeds. This allows for continuous expansion as disk capacities grow. Now, expansion is automatic, instantaneous and access to data is always maintained. To find out exactly how much free capacity you'll have with your choice of disk capacities, try out our interactive Capacity Calculator. Redundantly Safe Drobo can ensure your data is safe even if a hard disk fails. You’ll feel safer knowing that if disks do fail, Drobo automatically enters a state of self-healing wherein it relays out your data across the remaining healthy disks and sectors. Proportional Rebuild Times The time it takes Drobo to rebuild data after a drive failure or removal is proportional to the amount of data stored in the pool—meaning the less capacity that is used, even on a 2TB disk, the shorter your rebuild times will be. This is superior to traditional RAID, which lacks proportional rebuild times, and is forced relay out every bit even if it does not contain user data. Since Drobo is “Data Aware”, it tracks where data is on each disk, so it can differentiate between used and unused portions of disk. This expedites rebuild times and reduces your risk of losing data to an additional disk failure. In short, your data is safer on a Drobo. Self-Healing When Drobo detects a "bad" hard disk, it proactively advises you with a series of warnings ranging from a blinking red LED on its front panel, to pop-up alerts in Drobo Dashboard, to email alerts. What Drobo does next is exceptional. Entering a self-healing mode where it repairs around the bad sector or disk, Drobo will work until it returns to the safest state possible. If Drobo has sufficient time and free capacity (indicated by all lights returning to a solid green state), it can even withstand additional hard disk failures — that's the power of self-healing. Smart Volume Technology The innovative and timesaving Smart Volume technology integrated into Drobo allows a single virtual volume to pull storage from the common pool of disks rather than a specific physical disk allocation. Increasing the available pool of storage on Drobo is as simple adding or upsizing drives. Thus, there’s no need to reformat your file system or repartition. Storage Virtualization BeyondRAID was designed from the ground up to allow the storage capacity of the array to expand and contract. BeyondRAID makes this a simple process by utilizing a technology called “virtualization.” Virtualization provides a layer of abstraction between the data requested by the file system and the physical location of that data on the disk drives. A given piece of data can be located on any drive, and on any physical location on that drive. This is what makes adding a drive to a Drobo so simple. The new drive just provides additional places to store data. Virtualization is what enables BeyondRAID to effortlessly change the data arrangement on the drives, for example, changing data stored as a mirror into data stored as parity stripe, say, without interrupting the user access to data. Virtualization completely decouples the physical space available in the array from the space reported to the operating system. This is how BeyondRAID is able to remove the need to manually expand/contract the file system as more space becomes available or is removed. Thin Provisioning Thin Provisioning is a technical term that describes how the BeyondRAID technology communicates with your operating system. BeyondRAID communicates with your OS about how much disk space you have, up to 16TB (this varies with older operating and file systems). Specifying a larger amount of storage than is physically available allows you to grow into the volume without having to reformat or migrate your data in order to add capacity. BeyondRAID automatically also reclaims space as you delete files. Self-Managing Drobo is highly automated storage. There are no complex configuration screens, DIP switches, confounding choices, web consoles or other complications that prevent so many other storage devices from working out of the box. Drive Reordering One long-standing requirement inherent in traditional RAID-based systems was that if for some reason you needed to remove the drives, you’d have to replace the drives in the exact same order. When you remove your disks from Drobo, you can put them back in any order you like. ¹ Linux support in Beta Drobo Product Specifications Disk Interface  Four-bay capacity  3.5" SATA I or SATA II hard disk drives  No carriers required  Mix and match capacities, disk brands and speeds Capacity Continuously upgradeable with larger and faster drives.

Data Robotics, Inc. cannot guarantee all host systems will achieve similar results. ²Acoustics tests performed 1m from the front of Drobo with four 1TB Western Digital GreenPower™ drives during a file copy to Drobo. Drobo has a smart, five-speed fan governed by multiple internal temperature sensors that will normally be off or operate on its lowest setting. The fan is programmed to minimize noise, but never at the expense of disk integrity. The fan can switch to higher speeds if necessary in in hot operating environments or during strenuous usage to protect drives from overheating up to 38.1dB. ³ Linux support is currently in Beta.
