Using CASFS with Different Storage Backends
CASFS is a single global file system capable of spanning hundreds of machines, managing billions of files, petabytes of data, and delivering the full aggregate bandwidth of managed object stores. This shared file system maintains consistency over all clients at all times, with the updated metadata being visible to all clients in real-time. The file system supports ACLs as well as specialized access modes, and has a non-root superuser mode for giving users full access over the file system without enabling them to become root.
CASFS can store data, executables, and user home directories. Users can utilize CASFS as their home directories, housing their source code and data durably across all machines. No additional APIs or commands are necessary in order to work with the file system. There is no need to mount/unmount the file system by the end user, and no extra procedures for entering/exiting the file system. This allows the applications and users to lift and shift their existing infrastructure and work with the data that exists in cloud storage or on-premise data stores.
CASFS can easily be configured to work with different storages. In this paper, we run benchmarks to examine file system operations performance on EBS and S3 on AWS. We also examine the file system operations performance on FlashArray and FlashBlade in the PureStorage environment. With CASFS running on any system that has connectivity to the server, the whole storage is mounted on a directory, and the structure, as well as permissions and all file system metadata, are instantly available on the system. Doing tests on different file systems is as simple as changing the test path.
CASFS is built on a client-server model. On both environments, we run an FSDB metadata server on one instance and a client on another. We run the tests on the client, which has the CASFS file system mounted. The nodes used on AWS are c5n.2xlarge with 8 cores of Intel Xeon Platinum 8000 series supporting up to 8 concurrent threads, with 21 GB of memory and an EBS local storage. The client node used on the PureStorage environment is a VMware virtual machine that has 8 cores of Intel Xeon Gold 6000 series with 24 GB of memory and a FlashArray local storage. Appendix 1 lists the information on both systems.
We use Filebench to test file system performance with different workloads and evaluate the two environments in different aspects. All tests run on the system's local file system, as well as on CASFS. The workloads that we use in our tests are described below:
listdirs
Create 60,000 files with size 0 in directories with the mean number of entries per directory equal to 4,000. The benchmark starts by performing list directory on all the directories repeatedly for 30 seconds. This test does not have any interactions with the underlying storage, and the throughput shows the userspace file system performance, as well as the network performance between client and server. The results below show that the network throughput on AWS and Pure are comparable.

statfiles
Create 10,000 files with sizes determined by a gamma random distribution (min=1, mean=5k, gamma=200) in directories with the mean number of entries per directory equal to 1500. The benchmark starts by performing stat on the files repeatedly until 50,000 stats are done. The benchmark of this test does not have any interactions with the underlying storage, and the throughput shows the userspace file system performance, as well as the network performance between client and server. The results below show that the throughput on AWS and Pure are comparable.

readfiles
Create 100 files (each 100 MB) in directories that have 2 entries on average, and open all files. The benchmark starts by doing random reads on the files repeatedly for 5 minutes. As the results show, CASFS takes advantage of the faster FlashArray as its local files cache and gets a better throughput in the reads.

singlerandreadopen
Create 1 file with size 1 GB. The benchmark starts by opening the file, doing a random read on the file, and closing the file; it repeats this cycle over and over for 5 minutes. These results show the effect of excessive open/close operations on CASFS since they require extra internal processing. CASFS takes advantage of the faster FlashArray as its local files cache and gives a better throughput in open-read-close with FlashArray, compared to EBS as an underlying cache storage.

writes
The benchmark starts by creating 10,000 files (100 KB each) in directories that have 200 entries on average, and then opening all files. Next, it rewrites on all the files (all 100 KB of data) six times. Finally, it closes all the files. The network performance and FlashBlade performance are significantly higher than S3.

The benchmark starts by creating 10,000 files (100 KB each) in directories that have 20 entries on average, and then opening all files. Next, it rewrites on all the files (all 100 KB of data), and then performs fsync on all files. All the files are rewritten again with 100KB of data and are synced again five more times. Finally, all the files are closed, and the benchmark is done. This test is run on seven threads. The difference in throughput is linked to the metadata operations in fsync on the network between the client and the server, and the upload to the external storage on every fsync.
