What is the difference (from an operating system perspective where the file/object resides) between a file in mounted NFS drive and object in, for example Google drive? Isn’t object storage (under the hood) just network file system with rest API access?Ī. Or you submit a key-value and get the object (stream of 1s and 0s) in return. You submit data (stream of 1s and 0s) and get a key-value in return. The software makes these objects (full of 0s and 1s) available via a key-value systems and/or a RESTful API. Then The Storage Networking Industry Association (SNIA) came along… The short answer is some software (running in the storage server, storage device, or the cloud) organizes the 0s and 1s into objects stored in a file system or object store. Then there were chip companies, storage companies, and networking companies. In the beginning there were electrons, with conductors, insulators, and semi-conductors (we skipped the quantum physics level of explanation). How is data converted to objects or vice versa?Ī. ![]() Thus customers who care most about simplicity and minimizing their integration/support work tend to buy commercial appliances or storage software, while large customers who have enough staff to do their own storage integration, testing and support may prefer open-source solutions so they don’t have to pay software license fees. As is usually the case with other open-source, these solutions typically make storage (block, file or object) available at a lower acquisition cost than commercial storage software or appliances, but at the cost of higher complexity and higher integration/support effort by the end user. Open source software solutions are available for block, file and object storage. How do open source block, file and object storage products play into the equation?Ī. It was not the intention of this webinar to conflate cloud and object storage we leave that to the SNIA Cloud Storage Initiative (CSI). Security can be required and deployed in both enterprise and cloud storage environments, and for block, file and object storage. Cloud storage can be block, file, and/or object, though object storage is perhaps more popular in public and private cloud than it is in non-cloud environments. This is a very common problem with discussions of objects - they typically become descriptions of one vendor’s cloud features.Ī. I feel that this discussion conflates object storage with cloud storage features, and presumes certain cloud features (for example security) that are not universally available or really part of Object Storage. If you deploy local object storage that does not include any remote replication or erasure coding protection, you should implement some other form of backup or replication, perhaps at the hardware or operating system level. Most object storage systems have built-in data protection using either replication or erasure coding which often replicates the data to one or more remote locations. ![]() What is the best way to backup a local Object store system?Ī. File storage also often allows access to specific data within a file and in many cases shared writes to the same file, while object storage typically offers only shared reads and most object storage systems do not allow direct updates to existing objects. Another difference is the access method–folder/file/offset for files and key-value for objects. What is the main difference between object and file? Is it true that File has a hierarchical structure, while object does not?Ī. NFS and SMB both let you specific block I/O size. That is correct, block size refers to the size of data in each I/O and can be applied to block, file and object storage, though it may not be used very often for object storage. Regarding block size, I thought that block size settings were also used to tune and optimize file protocol transfer, for example in NFS, am I wrong?Ī. If encryption is offloaded to the HBA, drive, or SmartNIC then it might not affect performance. Encryption requires processing power so if it’s done by the main CPU it might affect performance. ![]() These methods can usually also be applied to block and object storage. Encryption of file data on the wire can be done by the storage software, OS, or specialized network cards. Yes, encryption of file data at rest can be done by the storage software, operating system, or the drives themselves (self-encrypting drives). What about the encryption technologies on file storage? Do they exist, and how do they affect the performance compared to unencrypted storage?Ī. As promised, our experts have answered them all here. This great debate generated many interesting questions. Object Storage.” If you haven’t seen it yet, it’s available on demand. More than 1,200 people have already watched our Ethernet Storage Forum (ESF) Great Storage Debate webcast “ File vs.
