We are experiencing problems with our systems wherein multiple clients connecting to a single NFS gateway server seem to exhibit problems reading or writing to the NFS server. The issues appear to be sporadic (probably related to load) and we have been unable to identify where the bottleneck is and how to fix it. I am looking for someone with the following qualifications... 1) The ability to diagnose and demonstrate the problem area 2) The availability to respond to a Skype message during the times this problem is occurring in order to log in and look at it at that moment. 3) Advanced knowledge of troubleshooting/diagnosing problems with storage-related systems including knowledge of NFS, iSCSI, etc. A few pieces of information about our setup and what we have done so far... 1) We are using a dell equallogic PS6500 SAN (48 1TB drives) - We call this machine EQ1 2) We have an NFS gateway machine connected to it via iSCSI that exports the entire volume. - We call this machine FS1... it is a physical machine with CentOS 6 installed directly on the hardware. 3) We have a number of VM's (approximately 9) that mount this NFS share and constantly read/write from/to it. These VM's use XenServer as their virtualization platform and are currently using "Linux Bridge" for communication with the NICs. 4) We have bonded 4 - 1Gb interfaces between FS1 and EQ1. These 2 share 1 switch dedicated to their communication. 5) We have bonded 3 - 1Gb interfaces on each VM to connect to primary switch for the network that FS1 is also on. (FS1 has 4 - 1Gb interfaces bonded and connected to this network) After you apply... pls send a message with your skype ID

We need to URGENTLY move our Ruby on Rails based app from a single server to something that is more redundant AND secure. The application stack is as follows; * Ubuntu LTS * Ruby 2.2.x +Rails 4.2.x * Nginx + Passenger * Sidekiq to run background jobs * Separate java-based PDFServer to export documents to PDF + do operations on them * ElasticSearch to power search * Redis to handle caching + session handling + backgroung jobs * PostgreSQL as main DB * Loggly as external logging * New Relic to monitor APP * DataDog to monitor servers Our 2 main requirements: * There should not be any single point of failure in the solution * Data should be encrypted as much as possible (RDS, HTTPS...) We are open to doing a quick implementation now and then productify it using whatever the best technology is (docker, cloud66, ...)

I have an existing Digital Ocean account and I'm looking for a freelancer who has a LOT of experience working with Digital Ocean to set up a new droplet from scratch, ideally using an automated script. The droplet will need to be set up to run CentOS 7 and a standard LAMP environment, I will also need the server to support a number of hosts/domains in a virtual server environment. Although I don't want to go mad on security, I will expect all "common sense" security concerns to have been addressed. I have a subscription to CrashPlan and will also want the CrashPlan client to be installed and set up so that the system is backed up offline. I will also be purchasing an SSL certificate for at least one of the domains that will need to be set up on this server. Before the project will be accepted, a full "handover document" will be required outlining the steps taken to install, the tests carried out and specific instructions for starting and stopping each system component, details of all log files and their locations, details of all housekeeping required, and details of how to add and/or remove a virtual host from the configuration. When applying, please include the following information: How much experience you have working with Digital Ocean How much experience you have working with Linux in general Any particular specialities you have Details of similar jobs you have undertaken The approximate number of hours you expect to take to complete the job How long before you can start work on the job Please note: This is an initial project but more work will be available if this project goes well.
