Several years ago, Bezeq migrated from
an Oracle Exadata system to a Hitachi
UCP with internal Fusion IO and a Hitachi
VSP F400 all-flash array connected via
Fibre Channel.

But recently, the storage solution’s
insufficient throughput, slow response
times and inability to be expanded led the
IT team to seek a revamp.
“The Excelero NVMesh software-defined
technology is the only technological
solution that meets our performance
demands and has proven to be an excellent
decision,” said Igal Muginstein, Storage and
Backup Team Manager at Bezeq.
“As a leader in the national
communications market, we are on the
look-out for promising new technologies.
NVMesh is a highly advanced solution and
we have quickly seen the tangible benefits
of replacing the complicated server with
internal SSD and all-flash array with the
simplicity and scale of Excelero NVMesh.”
The new infrastructure incorporates
Excelero NVMesh running on a Fujistu
RX4770 server, featuring 96 cores and 1TB
memory, and Fujitsu RX2540 storage nodes
with 4 TB NVMe drives – totalling 48 TB.
The servers are connected with Mellanox
100 Gbps Ethernet switches and NICs. A
key benefit of NVMesh was the flexibility
to choose the most suitable and cost-
effective commodity hardware for Bezeq’s
requirements, eliminating vendor lock-in.
Early trials showed that in contrast to the
maximum 8 Gbps throughput of the Fusion
IO devices, the NVMesh environment
delivered 16-23 Gbps – well above Bezeq’s
requested 15 Gbps throughput.
The Excelero storage also reduced run
times by an average of 30% compared to
the legacy all-flash array environment and,
in some workloads, reduced run times by
up to 90%. Replacement was simple and
while formal metrics weren’t established,
Bezeq’s IT team detected reduced CPU
demand, helping it squeeze maximum
compute power from existing resources.
“The winners in the new telecoms
landscape will be those forward-thinking
