Small review of the Dell Storage SC7020 :

Dell’s Compellent Data Progression technology functions to optimize Storage in the page level with three page sizes: 512KB, 2MB, and 4MB. Incoming writes and hot information are tiered to the fastest storage and subsequently obsolete to lower-performance storage if it’s accessed less frequently. The Dell Fluid Storage Architecture allows files to be striped across drives for improved access times and also to execute tiering optimizations in parallel.

Storage Center 6.5 utilizes a virtualized storage paradigm which Consolidates all storage in one pool by default individual drives and volumes may support multiple RAID levels and do not require pre-allocation of all RAID groups. This single pool is available to all RAID levels concurrently, which permits individual RAID volumes to dynamically expand or contract as required at a 512KB block level. For consumers accustomed to legacy static RAID groups, it could be a bit odd to see a 5-disk RAID10 storage pool consequently.

With the debut of Application Protection Manager for Oracle and now improved for the Linux® environment, you can create application-consistent Replays for Oracle® databases. Coupled with Storage Center Data Instant Replay (DIR), it will ensure reliable program, consistent backup and recovery of Oracle and Microsoft Volume Shadow Copy (VSS) enabled applications (Exchange, SQL and Hyper-V) and VMware virtual machines (VMs).

Handle the SC7020 with the Dell EMC Storage Manager (DSM, formerly known as Enterprise Manager). It gives detailed monitoring and management of local and distant SC Series arrays. Easy-to-use data replication and migration between programs provides PS customers flexibility to add SC arrays for their environment when they choose. *

DSM streamlines SAN administration and reduces operating costs with innovative features like volume-level QoS, VVOls support and departmental “charge-back” reporting. Powershell and REST management APIs Enable You to integrate the SC7020 into your company workflows

Advantages of the Dell Storage SC7020 :

0-100% Flash architecture Target specific cost performance ratios with any mixture of SSDs and HDDs then alter the mix as your needs change. Insert more flash to boost performance, or “deep and cheap” spinning disk as chilly data volumes grow. Hot data will always be written to your fastest drives at the fastest RAID levels. Intelligent Data Reduction Like many SC solutions, Deduplication and Compression are implemented dynamically in a sub-LUN level to maximize performance and decrease capacity needs throughout the information lifecycle. Fully integrated with Information Progression, SC data reduction saves money on SSDs, HDDs — or equally in hybrid systems. Low-Cost Business Continuity Keep mission-critical programs running during unexpected outages and disasters with easy volume-level auto-failover between local and remote arrays. Complex Live Volume feature is native to SCOS — no extra hardware or software is required to make your “always available” storage atmosphere.

Performance

The StorageReview VMmark Protocol uses a range of sub-tests based on shared virtualization workloads and administrative jobs with results measured utilizing a tile-based unit. Tiles measure the capability of the system to carry out a variety of virtual workloads such as cloning and deploying of VMs, automatic VM load balancing across a datacenter, VM reside migration (vMotion) and dynamic data store movement (storage vMotion).

During the VMmark benchmark, the Dell Storage SC4020 Managed to Hold its own against the Huawei Dorado2100 and Fujitsu Eternus DX200F for as much as six tiles with results averaged across the various workloads. At six tiles, the SC4020 had an overall rating of 7.8, compared to 8.4 for the Dorado2100 and 8.5 for its Eternus DX200F. Determined by the VMmark application results, the SC4020 topped out in 9.3 for six tiles, compared to 9.9 for its Dorado2100 and 10.1 for the Eternus DX200F.

It should be stressed that VMmark measures both storage Performance, but also has a huge weight on storage capacity. In our setup using 2.18TB of usable storage, then we ran out of storage capacity to add additional tiles before the selection ran out of steam in the I/O load. To Put It Simply, adding more SSDs to bump up the capacity will both enhance the number of tiles the SC4020 can run

Conclusion

Dell’s SC4020 is the opening movement in a brand new mid-market strategy In the Dell Storage division. It builds on a heritage of hard-hitting enterprise storage arrays by integrating best-of-breed technology in the Compellent and EqualLogic households at a scale and price that was inaccessible from any significant players in the market.

The baseline MLC configuration we benchmarked for this review Managed a remarkable performance level in application benchmarks against much more expensive all flash arrays. Back in VMmark while the SC4020 awakened at 6-tiles, it didn’t run out of steam out of I/O but instead just capacity since each tile has approximately a 275GB footprint. Within our SQL Server database evaluation, the SC4020 quantified 20ms using its average response time, in comparison with 3-53ms in the other units we tested, which are almost 10X more expensive with higher drive counts. Switching to our artificial tests the SC4020 quantified 168k IOPS read and 53k IOPS compose in our 4K random I/O benchmark. In our 8k 70/30 benchmark looking at mixed workload performance we saw speeds top at 91k IOPS. These results only hint at what the SC4020 platform would be capable of when equipped with higher-performing drives as you step up the ladder of configurations Dell offers together with the SC4020.

For storage administrators at bigger organizations Searching to get a System that could integrate with their existing Dell Storage infrastructure, the SC4020 is easy to incorporate into existing management workflows and would be Perfect for remote office deployments with replication to the primary office. Smaller enterprises with storage administered by IT generalists will find the SC4020 to be a strong and accessible entry point to the Dell Storage Family, together with Dell Compellent’s robust data services and the Dell Copilot App adding considerable value for a variety at this price point. This is Where the SC4020 is unique; it delivers a robust feature set that’s Not only affordable (albeit at low capacity) but very mature also. Not only Has Compellent code already been around more than many all-flash or hybrid Startups have been in business, but the network of support that Dell has Developed, emphasized by the above Copilot, are rivaled by few. For true enterprise-grade storage and support, the SC4020 bundles a long legacy Of success into a true midmarket/ROBO form element. For those who can live Within the confines of even this $25k config, the results are extremely impressive And matched by no other vendor at this moment.
