ScaleIO is a software-only solution that uses existing servers’ local disks and LAN to create a virtual SAN that has all of the benefits of external storage, but at a fraction of the cost and complexity. May 09, 2016 · This saves time formerly required for transferring files to and from the workstation, but also can take place at a performance level higher than can be achieved from a single local drive (mechanical or SSD). However, to get performance necessary for direct-from-server editing, high speed connectivity is required. performance in a data warehouse/analytics environment, when the majority of the I/Os are reads. 2.1.3 Create Aligned Partitions Create an aligned partition by using the sfdisk command, starting a partition on a 1M boundary (sector 2048). Aligning to a 1M boundary resolves the dependency to align to a 4k, 8k or other boundaries divisible by 4k (for The fw is already the latest version, and I've even restarted the hosts. The 4k/8k/16k ib_read_bw results are fairly steady, around 87Gb/s. The thing I don't understand is that the 'rx_discards_phy' counter shows the adapter is running out of port receive buffer, but I can't find any useful information on how to enlarge this buffer number.

Introduction. This guide is designed to be used as a self-training course covering ceph. The first part is a gentle introduction to ceph and will serve as a primer before tackling more advanced concepts which are covered in the latter part of the document. Mar 23, 2017 · Ceph is good with spinning disks but not fast enough with SSDs; Many of the SSD vendors such as SanDisk,Intel,Samsung looked at making Ceph based solution and tuning it to SSD. Sandisk and Intel discovered performance issue/bug with a memory allocation library TCMalloc that affects small (4k) block sizes when using SSDs, correcting this issue ... • Some of the documents contain performance and tuning information • Commercial support available for professional services and software support • Intel will continue to work with its ISV and hardware systems partners on reference architectures • And continue Intel’s Ceph development focused on Ceph performance Ceph is designed to avoid single points of failure. And something that is of interesting to everyone, Ceph is freely available. Users can set up a Ceph node on commodity hardware that uses several intelligent daemons, four in particular: Cluster monitors (ceph-mon), Metadata servers (ceph-mds), Object storage devices (ceph- After you have learned to use Ceph clusters, the next module will teach you how to monitor cluster health, improve performance, and troubleshoot any issues that arise.
