  NSX-T Data Center   leverages BGP EVPN technology to interconnect and extend NSX-managed overlay networks to other data center environments not managed by NSX, VXLAN encapsulation is used between NSX TEPs (edge nodes and hypervisors) and external network devices to ensure data plane compatibility. Two connectivity modes are supported for EVPN implementation in  NSX-T Data Center : Inline Mode: In this mode, the tier-0 gateway establishes MP-BGP EVPN control plane sessions with external routers to exchange routing information. In the data plane, edge nodes forwards all the traffic exiting the local data center to the data center gateways and incoming traffic from the remote data center to the hypervisors in the local data center. Since the edge nodes are in the data forwarding path, this model is called the Inline model. Route Server Mode: In this mode, the tier-0 gateway establishes MP-BGP EVPN control plane to exchange routing information with the external router or ro...

Today, I am writing this post related to SDDC manager backup task failure with error message " Could not start SDDC Manager backup Backup failed : Unexpected error encountered when processing SDDC Manager Backup ". SDDC manager is running with VCF 4.5.1 version. We have configured the SDDC backups on a external SFTP server. Below is the screenshot of backup task failure. After checking the operations logs under   /var/log/vmware/vcf/operationsmanager/operationsmanager.logs we have found below entries related to backup failures that indicating issue with SOS client service and Too many files open in backup task.   2023-09-25T11:22:34.655+0000 ERROR [vcf_om,99cc8bcd8fbb453b,d881] [c.v.v.b.helper.SosBackupApiClient,http-nio-127.0.0.1-7300-exec-5] An exception 500 INTERNAL SERVER ERROR: "{"arguments":[],"causes":[{"message":"[Errno 24] Too many open files: '/var/log/vmware/vcf/sddc-support/vcf-sos.log'","type":...

VMware has announced the general availability of  VMware Cloud Foundation 4.5.2 . This release brings several new features, enhancements, and bug fixes to ensure that the Cloud Foundation platform remains the best choice for your cloud infrastructure needs. What's New The VMware Cloud Foundation (VCF) 4.5.2 release includes the following: Keyed to keyless license conversion:   The option to convert the licensing mode of a workload domain from a keyed license (VCF-S or VCF perpetual license) to a keyless license (VMware Cloud Foundation+) model is a now available. Support for mixed license deployment:   A combination of keyed and keyless licenses can now be used within the same VCF instance. The licensing within a given workload domain needs to be homogeneous (no mixing of keyed and keyless licensing within a workload domain). BOM deviation precheck:   Running an upgrade precheck now determines if the Async Patch Tool was used in the environment to patch components. B...

  VMware Cloud Foundation is VMware’s comprehensive software-defined infrastructure (SDI) platform for deploying and managing private and hybrid clouds.

  The announcement of the VMware vSAN Express Storage Architecture™ or ESA for short, represents a massive step forward in the capabilities of the solution, and the benefits to our customers.  This has been achieved in a way that is largely transparent to the user, in the same product they are already familiar with. The vSAN Express Storage Architecture is a new way to process and store data.  It is an optional, alternative architecture in vSAN that is designed to achieve all-new levels of efficiency, scalability, and performance.  The ESA is optimized to exploit the full potential of the very latest in hardware and unlocks new capabilities for our customers.  It is introduced in vSAN 8, and when using ReadyNodes approved for the ESA, can be selected at the time of creating a cluster.  The ESA in vSAN 8 is an alternative to the Original Storage Architecture (OSA) found in all previous editions of vSAN, as well as vSAN 8. The Express Storage Architecture in ...
